Projected polyurethane. How does it work?
If you still do not know what uses the projected polyurethane has, for the acoustic or thermal insulation, we leave you these videos so you can understand it better.

Technology and applications
Our job is to insulate ceilings, walls and buildings against noise, weather conditions and fire. For this we use the projected polyurethane -more known as polyurethane foam- as well as the fireproofed mortar.

Polyurethane foam
This material, also known as projected polyurethane or more colloquially foam rubber, has multiple applications in the world of construction, building and home.

Its properties make it a great thermal insulator, noise absorber and filling material for diverse.

Fireproof mortar
A mortar with mechanical projection to protect materials and packaging against fire and abrasion. For both indoor and outdoor use, it is capable of thermally insulating ventilated facades and roofs with a type B s1 d0 requirement.

The injected polyurethane significantly reduces energy losses, while isolating external noise. It is remarkable the durability of this material reaching a useful life of more than 50 years.



The 5 Advantages of EPS (Expanded Polystyrene VS PUR (Polyurethane Foam)

Because of the effects of global warming, it has become a necessity of the multiple industries in the world, integrate insulation systems in their construction projects, call buildings, vertical and / or housing industrial works, food grade among others.

Polystyrene has come to join the range of the most efficient and economic components for the production of insulating materials with an important degree of thermal resistance, which provides a substantial saving in the consumption of electrical energy in the construction industry.

1.     ECONOMY.- Polystyrene (EPS) is a cheaper material than Polyurethane.
2.     LIGHTNESS.- The weight of Polystyrene (EPS) is 10kg-45kg / m3 while the Polyurethane goes from 30kg-45kg m3.
3.     TOXIC LEVEL.- Polystyrene is expanded based on air, so it does not emit any toxic gas, harmful to health or the environment, while Polyurethane is a material that, when exposed to combustion, emits toxic, noxious gases to health.
4.     THERMAL RESISTANCE.- In the case of Polystyrene, it remains constant over time, as it does not suffer any loss or reduction of this, while the polyurethane foam begins to decrease its thermal resistance.
5.     DURABILITY.- The polystyrene only undergoes change in its appearance, (yellowish color) when exposed to the weather, while the polyurethane with the passage of time begins to undergo a spray and lose its properties.

Advantages of polyurethane insulation in Santiago and Ames

The projected polyurethane is a plastic material of cellular composition used as thermal and acoustic insulation and as a waterproofing in building and industry.

At Aislamientos Nogareda we work with this material because its properties are broad in its application.

Thermal isolation
The projected polyurethane is a highly effective thermal insulating material. The rigid polyurethane foam is currently the best thermal insulation solution for buildings, both for being the insulating material with the lowest thermal conductivity coefficient in the market, as well as for being a continuous and waterproof system.



LUCID 10 Inch King Latex Hybrid Mattress - Cooling Gel Memory Foam - Responsive Latex Layer - Adaptable - Premium Support - Durable Steel Coils

Humidity control
The projected polyurethane, being impermeable to water, allows transpiration to the enclosure.

In those constructive solutions where there is a risk of condensation it will be necessary to interpose a vapor barrier in situ to avoid pathologies.

Acoustic conditioner
The use of open cell foams, moreover, has a positive effect of acoustic absorption. It can suffer wear and aging, increasing its deterioration if it is seen.

Waterproofing of facades
The projected polyurethane, as it is a continuous intermediate system, meets the maximum degree of impermeability of the facades without the previous plastering in the simplest and most economical way.

Security in front of the fire
With the projected polyurethane it is very important to take into account its safety in front of the fire, especially limiting the external propagation of a fire.

Buildings that include polyurethane (PU) insulating products comply with fire safety regulations, including requirements for propagation, in a wide range of applications.

Sustainability
The projected polyurethane helps reduce thermal losses economically and guarantees the comfort of people. In addition to its use helps reduce the energy consumption of buildings, polyurethane waste can be reused as a load on high density panels.

Healthiness
Polyurethane is a completely innocuous and healthy material for man. Thanks to its hygrothermal properties, the polyurethane meets the requirements of CTE DB H3 to ensure the quality of indoor air inside buildings.

Polyurethane Foam is a synthetic and duroplastic material, highly crosslinked and non-fusible, obtained from the mixture of two components generated by chemical processes from oil and sugar: Isocyanate and Polyol . The mixture under suitable conditions of these two components will give us a foam of variable stiffness, according to the proportion of each of the two products that has been used.

Polyurethane foam, as thermal insulation and roofing.

About 5 cm of polyurethane foam equals 15 cm in polystyrene plates, with the advantage of having no joints. In a short time the investment of the application is paid, with the lowest consumption of energy used by your air conditioner.

The application of polyurethane foam waterproofs, insulates, and seals effectively , preventing the formation of moisture by condensation and eliminates possible thermal bridges.

polyurethane ceilings

Polyurethane foam by the Spray or Injection method, provides excellent insulation.

The layer of this foam can be applied to various surfaces: The application includes Tanks, Pipes, Refrigerating Chambers, Flotation Elements, Civil Construction. It is especially appropriate for Ceilings and Walls.


Polyurethane is presented as the ideal solution for the construction of new construction and rehabilitation of buildings , especially on the roof of these, which is the part where more heat is lost, seals all kinds of irregularities and cracks, levels inequalities, adds little weight to the constructive solution and improves the structural resistance of the whole, reason why the total sanitation of the substrate to be repaired can be avoided.

polyurethane foam application

The thermal insulation capacity of Polyurethane foam is not achieved with any other known insulating material.

This special feature is due to the very low thermal conductivity of the foaming gas occluded inside the closed cells.

The physical properties of polyurethane foam

Polyurethane foam is the material we use to make our garage column protectors . It is a very used material due to its special properties. Let's see more carefully what are the physical properties of polyurethane foam .

Physical properties of polyurethane foam

Polyurethane is an extremely versatile elastomer that is used in countless applications throughout the world. There are many properties of polyurethane foam based on its molecular structure.



Classic Brands Cool Gel Ventilated Gel Memory Foam 10.5-Inch Mattress, Twin XL

High load capacity

The polyurethane foam has a high load capacity both in tension and in compression. The polyurethane can change shape under a heavy load, but will return to its original shape once the load is removed.

Flexibility

Polyurethane foam works very well when used in applications of high bending fatigue. The flexural properties can be isolated allowing a very good capacity of elongation and recovery.

Resistance to abrasion and impact

Due to this property, polyurethane foam is very useful in applications where severe wear occurs, even at low temperatures. A very useful capaxity in garage protection .

Resistance to water, grease and gasoline

The properties of polyurethane foam remain intact (with minimal swelling) if immersed in water / oil or grease. Therefore, polyether compounds last for many years in underwater applications.

Production facilities

Compared to conventional thermoplastic materials, polyurethane has a relatively short manufacturing time, and tool costs are significantly cheaper.

Color range

Different color pigments can be added to the polyurethane during its manufacturing process.

Resistance to mold and mildew

Most polyurethanes based on poly ether are not compatible with the growth of fungi or mold and therefore are very suitable for tropical environments.

Resistance to hostile conditions

Polyurethane is very resistant to extreme temperatures, that is, to harsh environmental conditions. Likewise, many chemicals will not cause material degradation.

Electrical properties

The polyurethane foam has good electrical insulation properties.

These are the most remarkable physical properties of polyurethane foam , which provide some remarkable advantages over conventional materials such as rubber, metal or plastic.

Benefits of the use of polyurethane in electricity and electronics

•     Polyurethane resin has a series of properties that make it an ideal product for use in electronics and electricity.
•     Encapsulating capacitors and circuits provides protection against corrosion, moisture, chemicals, shock, dissipates heat, etc.
•     With some variations in the formula you can transform a resin, which is an electrical insulator, into a conductor, opening a new range of possibilities.
•     In Formulations we have an R & D department with the necessary resources to manufacture any solution that our clients may need, specific to each requirement in the case of the electrical, electronic, motorization, etc. sector.

Its properties allow multiple applications

The first way in which polyurethane was found useful was as foam. But if the foaming agents are removed, a resin with very surprising properties can be obtained.



Zinus Memory Foam 10 Inch / Supreme / Cloud-like Mattress, Full

Having no longer a cell structure, which gives it its foam form, loses the property of thermal insulation, but gains other very interesting qualities such as high hardness and resistance to compression, resistance to environmental elements (except for the UV rays), high dielectric strength and heat dissipation capacity. These characteristics make polyurethane resin an ideal product for use in electronics and electricity.
       
Encapsulation of circuits and capacitors

On the motherboards of many computers you can see capacitors and circuits covered with a hard product with a vivid color and a smooth surface. That product is the polyurethane resin that is used to encapsulate them and that protects them from corrosion, humidity, chemicals and shock. It also dissipates heat, prevents discharges and overloads and prevents the circuit layout from being copied, thus preventing its falsification (thus protecting intellectual property).

In addition, with slight variations in the formula you can transform a resin that is an electrical insulator into a conductor, opening a new range of possibilities.

Polyurethane resin is also used to protect the circuitry of lightning rods and prevents them from overloading when lightning strikes.

The epoxy resin in electronics

Another polymer that is used in electronics is epoxy resin. This has as an advantage, compared to the polyurethane resin, which is transparent and if it has protection against yellowing by UV rays it can be used to cover the LED lights, giving them protection and allowing the light to pass without problems.

 MC Polyurethane insulation

Description of rigid polyurethane foam

So far we have described rigid polyurethane foam as a very good thermal insulator, enumerating its fundamental properties. We will now see chemically what it is and how it is formed.

Basically, the rigid foam is obtained from three chemical components, whose denomination is the following:

•     1) - Polyisocyanate.
•     2) - Polyhydroxylated resin.
•     3) - HCFC 141b, expansion agent whose boiling point is 32ºC.

By mixing the three indicated components, the polyisocyanate reacts chemically with the polyhydroxylated resin generating heat, which produces the evaporation of the blowing agent. As a result, the mixture begins to expand while hardening, eventually reaching the formation of a foamed plastic, closed cells and virtually sealed. Inside the same the agent of expansion in gaseous state is caught, being the main responsible, by its very low thermal conductivity, of the very good insulating effect of this foam.



Zinus Memory Foam 5 Inch Bunk Bed / Trundle Bed / Day Bed / Mattress, Twin, Pink

In practice, the application procedure is relatively simple, since it requires only a few steps: The hydroxylated resin is premixed with the blowing agent, there being no chemical reaction in this case. At the time when it is desired to produce the foaming, the previous premix is ​​contacted with the polyisocyanate, thus producing the expansion and hardening process detailed above (Figure 1.)

Figure 1: Expansion and hardening process.

Very low heat transfer, fundamental characteristic of rigid polyurethane foams.

As is known, the efficiency of a material as a thermal insulator is measured through its value of thermal conductivity, which we will call K and one of its expression units, among others is:

Figure 2: Efficiency of a material as a thermal insulator.

This value indicates the amount of heat, in kilocalories per hour, that passes through the two sides of a plate of one (1) centimeter of thickness and one square meter of surface for each degree centigrade of temperature difference existing between said two faces (Figure 2). Therefore, the lower the thermal conductivity mentioned, the less amount of heat is transmitted through the material and then, the latter works better as an insulator.

Table 1 shows densities and coefficients K for some of the products usually offered on the market. In the exposed values ​​it can be seen that the lowest thermal conductivity corresponding to rigid polyurethane foam and, in fact, up to now , is the material with better insulating properties that is known.

A point to note, more important: if we look closely at table 1, with the concept of thermal conductivity in mind, we can realize that as the coefficient K decreases, the thickness of material to obtain a desired degree of insulation also decreases . Let's take an example: imagine the roof of an enclosure that we want to isolate for. For this we use rigid polyurethane foam, which has an average K coefficient of 2.0 and the calculated insulation thickness is, for example, 25mm. If we place agglomerated cork instead, we need approximately 80% more thickness, that is, 45 mm. If we used expanded polystyrene, this thickness would be approximately 36 mm, that is, 44% above the value indicated for the rigid polyurethane foam. All of the above is important when considering the cost of an insulation, since for the material in question the thicknesses used are lower and the application procedure is extremely fast, especially if the blow-off method is used. in detail later.

Expanded polystyrene

As an additional comment we will say that using smaller thicknesses of insulation can also make the possibilities more flexible
of design of a certain structure.

APV S.A. The advantages of a thermal insulation efficient with foam of polyurethane

APV has achieved a satisfactory market penetration in the area of housing more than a year after implementing the business unit dedicated to the application of polyurethane foam. The reasons? A thermal insulation of excellent characteristics, combined with a team of experts in its application and the use of first level technology. We talked with Daniel Henríquez Vallejo, Civil Industrial Engineer of the Catholic University and Head of Development of APV, about the characteristics and strengths of this system.



LUCID 14 Inch Medium-Plush Memory Foam Mattress - Ventilated Gel Memory Foam + Bamboo Charcoal Infused Memory Foam - CertiPUR-US Certified - 10-Year U.S. Warranty - Queen

What is polyurethane foam?
Polyurethane foam is a thermal insulator with excellent characteristics. It consists of two chemical compounds that, when mixed, expand and adhere to the surface, creating thermal insulation. This mixture is made by a special team of Graco brand, the Reactor E-20, ideal for these applications, since it has been developed for that purpose by a globally consolidated brand, using the highest technology.

What are its advantages?
Compared to glass wool or expanded polystyrene, polyurethane foam is able to insulate with thicknesses 40% less. According to the thermal regulation, in the roofs of Santiago a thickness of 8.19 cm of glass wool would be required, while with polyurethane foam only 5 cm would be needed. Glass wool is a good insulator, but over time it deteriorates and loses its insulating capacity. To maintain optimal levels of thermal insulation this product should be replaced in five to ten year terms. Polyurethane foam does not lose its properties over time. Another advantage of this is that it adheres to any surface, which greatly benefits the application in walls and ceilings. In addition, by not having unions, thermal bridges are eliminated, which is where energy is generally lost. It also has good properties as a waterproofing, since it does not allow the passage of moisture and, being completely sealed, it solves problems such as leaks or others. Thus, its advantages can be summarized in duration, adhesion, structural resistance, energy saving and waterproofing.

What is its impact in terms of energy savings?
In practical terms, we have estimated that our product can reduce energy expenditure between 30% and 40% in a house, achieving a rapid return on investment through this energy saving. With the serious energy deficit that our country has, added to the high cost of fuel and electricity, it is necessary to make a contribution and we believe that this product should contribute with its grain of sand. With respect to the ecological requirements, it complies with the regulations and requirements to protect the Ozone layer.

Another feature is that this material has a fire retardant retardant that makes it hardly combustible. The future development of this product goes hand in hand with new constructions. It is necessary to encourage real estate companies to use superior methods of thermal insulation and thus support energy saving policies. It is proven that the so-called "ecological" constructions will gain more and more importance and people are willing to pay more for them.

How do you apply this product?
APV has an expert team in the application of this product and use of the equipment, and sees in this business a great development opportunity in the future. Polyurethane foam is a thermal insulator with excellent characteristics that we believe will be very important for future real estate developments and for anyone who wants to improve thermal insulation in their home and save energy in the process. For any question, you can contact us by sending an email to aplicaciones@apv.cl and we will gladly answer your requirements.

These are some examples of projected polyurethane m2 prices, only the product, without counting labor, machinery and other costs.

•     Foam projected "in situ", density 35 kg / m³, average thickness 30 mm, Euroclass E reaction to fire: € 2.98
•     Density 40 kg / m³, average thickness 50 mm, Euroclass E: € 5.10
•     Density 40 kg / m³, average thickness 80 mm, Euroclass E: € 6.52

We will mention the aspects that you have to take into account to calculate the projected polyurethane foam price, all of them increase the final cost per square meter (m2).

•     Thickness : influences the thermal insulation and is regulated by the CTE according to the climatic zone. In provinces where it is colder they require greater thickness as we can see in the image.
•     Density : in spite of the fact that polyurethane is a solution that generates a waterproof foam membrane in the thermal bridge, it allows transpiration to water vapor.

    The density of the material facilitates that the permeability to the steam is greater or smaller, so according to the risk of condensation of the building you will apply more or less. The higher the density, the higher the cost.

•     Behavior before fire : taking into account the use of the construction and its final application (plastered cement, plastering plaster, metal cover, etc.) you have to project polyurethane of one kind or another, classified in Euroclasses.
•     Surface condition : the thermal insulation of polyurethane requires that the receiving surface is prepared, clean and without moisture, otherwise it will have to be treated and the price will increase.
•     Indirect costs : here comes everything that has nothing to do with the material itself, ie, labor, difficulty of execution and necessary means (scaffolding, lifting cranes, etc).

Steps for the projected polyurethane

If you do not know how to project polyurethane by yourself, the first thing you should know is that this job requires in most cases a qualified professional and company with an applicator stamp, we do not recommend applying the insulation yourself.


    The first thing is to have an individual protection equipment for access to work: helmet, diver and very important, mask for organic gases.

•     A polyurethane projecting machine in which you control the power, the flow, the pressure, and that you can plug into an external power outlet.
•     Review the manufacturer's product quality sheet.
•     Protect all elements susceptible to being stained by the insulation product.
•     Check that the surface on which it is going to be applied is in good condition: consistent, dry, clean and free of obstacles.
•     Otherwise, it should be reviewed for possible breakage, cracks, holes, lack of mortar between pieces, etc.
•     To control the conditions of temperature of the substrate (superior to 5 ºC) and humidity of the atmosphere (inferior to 80%) for an optimum application.
•     The projected polyurethane is carried out with a previous primer on which it will be applied in successive layers of about two centimeters of maximum thickness until achieving the desired thickness.

    On old supports, it is advisable to carry out adhesion tests.

•     The application performance of polyurethane foam is about 100 square meters per hour.
•     The applicator will collect thickness measurements of the entire surface with a graduated punch no more than 2 millimeters thick.
•     The work carried out according to the current regulations will be measured.
•     In case the projected polyurethane is exposed to the weather (6 months - 1 year), it should be protected from direct solar radiation to prevent its degradation.

Applications of projected polyurethane insulation

Let's see at a quick glance the most common constructive solutions where polyurethane sprayed insulation is applied.

•         Insulate interior facade: when you do not want to touch the exterior facade because it is made of stone or brick, you can do the rehabilitation from within.
•         Isolate the facade exterior (SATE system or ventilated façade): this is the best method since you effectively protect all the sites where the cold of the street comes in (fissures, cracks) and waterproof the façade.
•         In old buildings whose facade is formed by two brick partitions with an air chamber in the middle, empty, this can be filled with projected polyurethane.

projected polyurethane facades

•     Terrace floors: just apply the polyurethane insulation layer and protect it with the desired finish. The cheapest is to paint, but you can put on tile or other materials.
•     Before the projection of the polyurethane check that the surface (tape, asphalt cloth, etc) is in good condition, otherwise remove it to avoid problems.
•     Waterproofing flat and inclined roofs: the roofs can be insulated, as well as the facades, both inside and outside under roof tiles.

• - A method of external insulation without interfering with the use of the premises.
• - Lightness
• - Great adhesion on the materials normally used in construction and industry.
• - Low absorption of moisture.
• - Easy application.

Among the main characteristics of expanded polyurethane we can highlight:

•     Lightweight
•     Rigid
•     Stable
•     Resistant to chemical products
•     Optimal for temperature insulation between - 200º c and 110ºc
•     Easy to cut and mold
•     It does not constitute food for worms and insects
•     Offers resistance to fungi
•     Non-aggressive to other materials
•     Stable Volume

The production of polyurethane foam takes place "in-situ", in the same place of installation. To do this, mobile machines are used, which dose and mix the components. There are two types of processes: projection and casting.



Classic Brands Cool Gel and Ventilated Memory Foam 12-Inch Mattress, CertiPUR-US Certified, Twin XL

- Projection process: It consists in spraying, by means of the aforementioned machine, the mixture of the 2 highly reactive components on the surface to be isolated. Here it expands and hardens quickly. The application is made in successive layers, until reaching the final desired insulation thickness.

- Casting process: in this case, the liquid mixture of the 2 components is filtered in the cavity to be isolated, with a reactivity adjusted to the process. In a short time, the mixture expands (filling the cavity) and hardens.

TECHNICAL INFORMATION

Cell structure: The rigid polyurethane foam has a predominantly closed cell structure. The percentage of closed cells is normally above 90%.

Density: The density of rigid polyurethane foam for thermal insulation is, depending on the application, between 30 and 100 kg / m3, and higher densities can be made for special cases.

Thermal conductivity: The high thermal insulation capacity of rigid polyurethane foam is not achieved with any other known insulating material. This special feature is due to the very low thermal conductivity of the foaming gas occluded inside the cells.

Water absorption : The absorption of water by the rigid polyurethane foam occurs as a function of environmental conditions and can take place by wetting or diffusion and condensation of the steam. It is influenced fundamentally by density and dimensions. In any case, the humidity content, in practice, does not exceed 5% in volume.

Resistance to the transmission of water vapor: In applications with high vapor / temperature gradients (for example, refrigeration applications, ...) it will be necessary to place a vapor barrier on the hot side of the insulation to avoid condensation. It would also be necessary to install a vapor barrier in some cases of insulation and waterproofing of roofs, depending on the climatic zone, or if the finishing or protection of the foam is made with a product that is resistant to the passage of water vapor.

Stability / Resistance: The rigid polyurethane foam is resistant to the materials commonly used in construction. In addition, the rigid polyurethane foam is: Resistant, to a large extent, to the solvents normally used in adhesives, paints, bituminous pastes, preservatives for wood and sealants. Resistant to aging, against the action of roots and inert biochemically, for example, against molds. Stable against fuels, mineral oil and diluted acids and alkalis. Resistant against the action of the exhaust gases or the more agressive industrial atmosphere. Imputrescible, stable to the detritus, odorless and physiologically does not present disadvantages. It is chemically neutral.

Fire behavior: Rigid polyurethane foam, like all plastics, is a combustible material. However, there are polyurethane foams classified from M1 to M4, according to UNE 23727, which must be applied according to the risk to which they will be exposed.

Thermal behavior: The thermal expansion of rigid polyurethane foam due to temperature is a function of density and substrate fixation. Each material has a certain variation in its dimensions when the temperature varies. In addition, in the case of rigid polyurethane foam, there is a gas occluded in its cells that causes a pressure drop, with cold, and an overpressure, with heat. Therefore, by shrinkage a contraction occurs and by heating a dilation of the cellular structure.

Electrical properties: The rigid polyurethane foam has very low dielectric and reflection losses, as well as a very low dielectric constant. For this reason, rigid polyurethane foam is suitable for applications such as antenna coatings and radar domes.

Physical Characteristics: a Applied density (ISO R-845): from 35 to 60 kg / m3 depending on whether it is impassable or not. b) Closed cap contents (ASTM D 2856): min. 95%. c) Thermal conductivity (ASTM C 177): 0.018 to 0.020 watt / m * C. d) Resistance to compression in the direction of foam growth (ISO R-844): 2.5 to 5.5 kg / cm2. e) Absorption of water (ISO 2896): max: 2% (VOL.%). f) dimensional stability (UNI CT 242/74): max. one%. g) Behavior in the presence of fire (ASTM 1692): meets standard.

What are the thermal properties of polyurethane foam?

Applications of polyurethane foam

Polyurethane foam has multiple uses in today's world, some of them are:

•     In mattresses as a main padding or as part of the padding;
•     In furniture, in sofas and chairs seats, stuffed with cushions, etc.
•     In construction, as a thermal insulator or as a filler;
•     In the automotive industry as the main element of defenses, seats, etc.
•     In many items such as toys, clothing, sponges, shoes, pillows, cushions, packaging and in general all types of padding or fillers.
•     In general, flexible polyurethane has applications such as cushioning in furniture, mattresses, under carpets and car interiors. It also offers good performance as a shock absorber with packaging and automotive applications.

Rigid polyurethane foam

The rigid spray polyurethane foam is the most effective way to simultaneously isolate and seal virtually any type of substrate, since it produces a monolithic layer without joints or thermal bridges, adhering by itself in a hermetic way. It is applied on any type of surface that is clean and dry.

The rigid foam has several applications such as:

•     Insulation and waterproofing of ceilings, slabs, dividing and acoustic walls.
•     Refrigerators and cellars
•     Structural reinforcement, panels
•     Insulation of hot water pipes, heating ducts.
•     Bodywork of trucks and minibuses
•     Bases of roofing surfaces as anti-noise and waterproofing
•     The polyurethane foam has excellent resistance to water, salt water, oils, very diluted acids and alkaline solutions. It is not affected by fungi, bacteria and odors and eliminates excessive noise.

The thermal properties of polyurethane foam

Polyurethane foam is a resource increasingly used, not only for sealing doors, windows and sanitation or repair of walls to insulate from the cold, heat and noise pollution homes, but also as a decorative element.

Some of the characteristics of polyurethane foams that have made it an excellent insulating material are its good thermal properties, since it offers a great resistance to extreme temperatures, maintaining all its technical properties in a spectrum that goes from 50ºC below zero or at 110ºC.

The plates or panels that are made are easily adjustable to any need, since they can be cut, perforated, painted, polished and glued with precision. Other advantages of polyurethane foams are their reduced weight and their absence of dripping in case of fire.

When using it, we must know that these foams can increase from two to five times their volume since they are applied until they are completely hardened. When applying the foam, it adheres to everything that comes in contact with it, so it is advisable to protect those areas that are close with special adhesive bands.

In the market you can find sprays of polyurethane foam of two types, which are constituted exclusively by polyurethane or compounds that have another element (besides the polyurethane) with which they make the reaction.

The main difference is that single-component foams harden as a result of contact with air humidity, while composite foams react when the two components are mixed and harden more quickly than the first.

Advantages of polyurethane

•     Solves leak problems
•     It is not flammable.
•     It can be painted.
•     Seal any area safely.
•     Product of very long duration.
•     It does not allow condensation to occur.
•     Extends the useful life of the treated surfaces.
•     Controls dilatations in concrete structures.
•     It acts as a vibration damper.
•     Energy saving used in cooling or heating.

Forms of application of polyurethane

•     In situ by projection or projected polyurethane : it is obtained by simultaneous pulverization of the two components on a surface, partitions, naves, roofs, terraces, farms, etc.
•     In situ by casting, or injected polyurethane : in which the two components are mixed and introduced through a hole previously made in the partition, for expansion. Isolating in this way all the space between the two partitions of the house. It is the method used in houses already built that do not have insulation.

Properties of polyurethane foam
The rigid polyurethane foam is a duroplastic synthetic material, highly spatially crosslinked and non-fusible. In the usual densities, for thermal insulation, the foam contains only a small part of the volume of solid matter (with a density of 35 kg / m³ , only about 3% of the volume is solid matter).

Next, we detail the properties of polyurethane foam.


Cell structure

The rigid polyurethane foam obtained by projection has a predominantly closed cell structure. The percentage of closed cells is above 97%.

Density

The density of the rigid polyurethane foam by projection for thermal insulation is included and standardized in Standards UNE 92120-1 and 92120-2 according to the application, between 30 and 55 kg / m ³ . Although, for special applications, higher densities (100, 200, etc.) or lower densities (acoustic foams: 10, 12, 15, etc.) can be used.

Thermal conductivity

The high insulating capacity of rigid polyurethane foam by projection is not achieved in the construction with any other known insulating material. This special feature is due to the very low thermal conductivity of the foaming gas occluded inside the closed cells.
In this way, the rigid polyurethane foam produced "in situ" can reach a thermal conductivity value of 0.022 W / m • K. Because the cells do not completely prevent the diffusion of gases through their walls, this conductivity value increases slightly with time until it finally stabilizes. In practice, the thermal conductivity value of the foam is considered to be that obtained after 9 months of aging (UNE 92120-1), 0.028 W / m • K.
By applying coatings that prevent the diffusion of gases (vapor barrier) it is possible to achieve that the thermal conductivity of the foam does not show appreciable alterations with time, maintaining values ​​of 0.023 W / m • K.

Water absorption

The absorption of water by the rigid polyurethane foam by projection occurs as a function of environmental conditions and may take place by wetting or diffusion and condensation of the steam. It is influenced mainly by density.
The absorption of water by short-term partial immersion of the rigid polyurethane foam according to the test is less than 0.13 kg / m². It must be borne in mind that the greater amount of water considered is due to the one remaining in the cells that are broken when making the cut to make the test piece.
By vapor diffusion and subsequent condensation, the isolations can absorb water depending on their situation and the temperature and humidity to which they are subjected. In practice, it is necessary to avoid reaching unwanted limits of humidity by diffusion of water vapor modifying the constructive solution. It can be done by increasing the density of the foam or in very extreme cases by placing a vapor barrier on the surface adjacent to the interior of the room (hot side of the insulation).

Resistance to the transmission of water vapor

The values ​​that characterize the resistance to water vapor are the dimensionless mu, or, the resistivity to the diffusion of water vapor.
For rigid polyurethane foam by projection for thermal insulation, in densities 30-60 kg / m ³ , the resistance to the transmission of water vapor ranges between 330-825 MN • s / g • m, being the dimensionless factor, of resistance to the transmission of water vapor from 60 to 150. These values ​​guarantee - in the majority of thermal insulation solutions by rigid polyurethane foam and depending on the density that we adopt - the absence of interstitial condensation, allowing its time the perspiration of the enclosures. Understanding that the transpiration of the enclosures in the building is the most beneficial effect both to avoid pathologies of all kinds, hygiene, health, comfort, etc.
In applications with high levels of steam and / or temperature (for example, cold rooms) it will be necessary to place a vapor barrier on the hot side of the insulation to avoid condensation. In residential buildings the most critical values ​​are usually manifested in flat roofs because waterproofing prevents transpiration.

Stability / Resistance

The rigid polyurethane foam obtained by projection is resistant to the materials commonly used in construction.

In addition, rigid polyurethane foam by projection is:

• - Resistant, to a great extent, to the solvents normally used in adhesives, paints, bituminous pastes, preservatives for wood and sealants.
• - Resistant to aging, against the action of roots and inert. Biochemically, for example, against molds.
• - Stable against fuels, mineral oil and diluted acids and alkalis.
• - Resistant against the action of the exhaust gases or the more aggressive industrial atmosphere.
• - Imputrescible, stable before detritus. Inodora and physiologically does not present disadvantages.
• - It's chemically neutral. Fire behavior: the rigid polyurethane foam has an M3 fire classification. Thermal expansion: the thermal expansion of rigid polyurethane foam by projection due to temperature is a function of density and substrate fixation.

Closed cells and open cells
Each material has a certain variation in its dimensions when the temperature varies. In addition, in the case of rigid polyurethane foam, there is a gas enclosed in its cells that causes a drop in pressure, with cold, and an overpressure, with heat. Therefore, by shrinkage a contraction occurs and by heating a dilation of the cellular structure.

With the usual density, 35 kg / m³, the coefficients of contraction, or expansion of the rigid polyurethane foam, are between 5 and 8 x 10-5 K-1.

The open cell foams, by not using gases of low thermal conductivity, have a cost of raw material approximately 20% lower. In addition, as the applied density of the product is lower, the required amount of material per m² is reduced between 15% and 30%. However, the implementation in order to obtain the minimum benefits required by the project and the current legislation implies additional costs. The application of an open cell polyurethane system, in direct replacement of a closed cell one, without the necessary corrections (greater thickness, mortar plastering, vapor barrier, etc.) can cause multiple problems:

•     Breach of project and / or legislation.
•     Poor insulation and higher energy consumption.
•     Absorption of water in the insulation and deterioration of the insulating properties.
•     Appearance of humidity and mold (unhygienic).
•     Water filtrations. Both the manufacturer and the installer have the obligation to adequately inform their client of the type of product and its suitability for the different constructive solutions.

Polyurethane foam - Thermal insulation

At Solfoam and Coatings we explain in a simple way the multiple uses and benefits obtained by using polyurethane foam in different buildings. Basically it is a porous plastic substance that is used to seal and isolate surfaces, noted for its excellent resistance to contraction and dilation movements.

This foam is recommended for thermal insulation , as it is a long-term solution with high efficiency due to its low conductivity and optimal control of the so-called thermal bridges.

If it is acoustic insulation it is also a highly recommended material, thanks to which it reduces the passage of sound waves coming from the interior and exterior noise.



Queen Mattress, Sweetnight 10 Inch Gel Memory Foam Mattress in a Box, CertiPUR-US Certified Foam Mattress for Movement Isolating, Sleep Cool & Supportive, Premium Cloud-Like Comfort, Queen Size

Another advantage is that it allows humidity control due to its waterproof characteristics, resisting the passage of water and steam with great efficiency. Contact us to guide you on the polyurethane spray , you will see that it is a very practical solution and full of benefits.

Waterproofing

When one thinks about waterproofing , the first thing that comes to mind is a simple protection of walls and ceilings to avoid the formation of leaks. And of course, if you give yourself something more than annoying, be in the warmth of your home or working in your office and suddenly have to place buckets in a downpour.

It is very true, but the problem of filtering water in all types of buildings goes further. When there are ceilings with cracks that allow the passage of moisture, in addition to the obvious, there is a huge potential for danger.

And no wonder, water can pass through slabs, walls and reach the foundations, leading to premature wear that would lead to a structural weakening of each house or building. There would also be an affectation in pipes (oxidation), cables, paint, etc.

At Solfoam and Coatings we are specialists in the subject, call us and we will gladly give you professional advice on the spaces you are considering for your waterproofing .

Choose thermal insulation material

There is a wide variety of thermal insulation material on the market, and you can choose synthetic, natural, mineral, as well as in different formats such as plates, rolls, etc. Before starting a waterproofing and thermal insulation project , it is necessary to know the main characteristics of each, to choose the most convenient in terms of savings in heating and air conditioning .


The material is the most fundamental when choosing an insulator , since it determines the level of insulation, and their requirements to apply them. It is advisable to read the instructions and labels included before placing them.

The presentation of the insulating material is another of the points to know before starting the project, since it determines the form, the work and the time it will take to apply it. Remember that not all formats are suitable for all works.


In general, the insulating material comes in the following presentations:

•     Plates or panels
•     Rolls, blankets and non-rigid panels
•     Foams
•     Particles, balls, fluff, fibers

Polyurethane foam as insulation

Polyurethane foam is a construction material whose insulating capacity can hardly be found on the market. It is used as thermal and acoustic insulation, as waterproofing facades and even as a humidity controller.

Below is a list of its main uses:
Polyurethane foam has the property of preventing the transmission of heat . Thanks to its low thermal conductivity, it is possible to achieve high levels of insulation without the need to resort to large thickness measurements.



Zinus Ultima Comfort 12 Inch Euro Box Top Spring Mattress, Full

What, for example, glass wool or expanded polystyrene would take 2 "and 1.6" of thickness respectively, the rigid polyurethane foam would take only 1 "; the advantages in terms of space gain are obvious.

The closed cells and low density polyurethane foam allow you to reduce the transmission of noise . It has a very positive sealing effect on the enclosures, hence it is very effective in the isolation of airborne noise.

For purely acoustic insulation purposes, the most suitable polyurethane foam is low density and open cells , as they are designed only to neutralize the noise. Therefore, it should be noted that it should not be confused with closed-cell polyurethane (which are the most recommended for thermal insulation).
The polyurethane foam has the quality of being an intermediate continuous system and a non-hydrophilic thermal insulation. Therefore, placed on a facade is able to meet the highest standards of waterproofing and without greater complexity in the installation.

The ATEPA, Technical Association of Applied Polyurethane, has led a series of tests in which the polyurethane foam was placed on brick facades; as a result, after a good time, neither rainwater nor any other source had leaked through one of those facades.

However, since polyurethane foam is an impermeable material, it automatically becomes permeable to water vapor . However, this degree of permeability can be reduced by increasing the density of the foam, whereby the polyurethane becomes, rather, a moisture-regulating membrane.

What does this mean in a few words? That the polyurethane foam allows transpiration to the enclosure and avoids superficial or interstitial condensation.

Insulating plastics: Polyurethanes

Since Otto Bayer in 1937 got the first synthesis of polyurethane this material has become an everyday element in our lives. We can find polyurethane in different products; in the field of medicine as a housing for medical devices, in the transport sector as an integral part of vehicles, in sports equipment, in building elements as a thermal and acoustic insulation element, in waterproofing and floor coverings, among many other applications .

The polyurethane is obtained by reaction of two components; a component containing at least two alcohol functional groups, -OH functional group, called polyol, and a component containing at least two functional group -NCO, called polyisocyanate. To these two components must be added several additives that will determine, together with the characteristics of the polyol and the polyisocyanate used, the final properties of our product. The polyurethanes can be thermoset or thermoplastic. We can classify thermosetting polyurethanes in flexible polyurethane foams, rigid polyurethane foams, integral skin foams and RIM polyurethane, without forgetting the paints, varnishes and coatings in general (pavements, waterproofing membranes) on polyurethane base.

The flexible polyurethane foams have a limit of resistance to the application of a load, their internal structure is open cell, permeable to air and have an elastic behavior against deformation 1 . Flexible polyurethane foams are used mainly in the mattress, upholstery and automotive industry ...

Success stories of innovation in automotive plastic

Compared with other insulating materials , rigid polyurethane foams have one of the lowest values ​​of thermal conductivity. In addition, it is important to highlight the soundproofing properties that they show. We can find numerous applications of this type of polyurethane as insulation in refrigerators and freezers, industrial plants (tanks, pipes, shipbuilding ...) and other projects of soundproofing and thermal insulation in construction and automotive.

If we make a careful balance between all the reactions that occur during the formation of the polyurethane foams, adjusting the temperature of the mold, the type and amount of foaming agent, and the packing of the cells, we can achieve the formation of molded parts with a cell structure core covered with an outer skin of the same material, this type of material is called "integral skin" (DIN 7726). The pieces made of integral polyurethane foam normally have a high reactivity, which is why it was necessary to introduce new transformation processes that allow the dosing and mixing of large quantities of raw materials in short periods of time.

The advance in these processing technologies led us to what is known today as the RIM (Reaction Injection Molding) process. The integral skin foams and RIM materials offer us advantages in the construction and design of molds due to the range of mechanical properties they offer and the wide variety of surface finish and density distribution. Its application in the automotive industry is of special relevance because using integral skin parts it is possible to reduce the weight of the pieces satisfying the required mechanical properties which is fundamental to reduce the weight of the vehicle (thus reducing CO emissions). 2 ) and maintain the safety parameters. Other fields of application of this type of products are sporting goods, furniture and casings of electronic, medical, ..

According to experts, the ideal way to keep the heat in the
interior of the house during the winter time and to keep it out
in summer it is reinforcing the strategic points by which the air and the
Heat is dispersed: walls, ceiling and floor. There are different materials
insulators that should be known to apply the solution that most
fit to the houses, one of them is sprayed polyurethane or foam
rigid polyurethane, which is composed of two chemicals A (polyol) and B
(isosionate or catalyst) and is highly thermal, acoustic and impermeable.

The result of the combination of these two chemicals, when applied by
sprinkling offers advantages among which are: sealing of surfaces
as hollows or cracks with a monolithic, homogeneous and impermeable layer and
with a smooth final texture thanks to its careful reactivity
Balanced, which can be applied on any type of substrate:
metals, plastics, wood and concrete among others.

For its important characteristics of thermal insulation, polyurethane
spraying of value K and R has certifications endorsed by the
National Organization for Standardization and Certification of Construction and
Building S.C (ONNCCE), Trust for Energy Saving
Electricity (FIDE) and by the National Housing Fund Institute
for Workers (INFONAVIT).

The main functions of the extruded polyurethane are:

* / Thermal insulation ./* Saves up to 40% in energy
electric, applied in refrigeration or freezing chambers.

* / Acoustic insulation ./ Removes noise in cinemas, rooms
audition or machine rooms, among others.

* / Waterproof insulation. / * When applied outdoors, it reduces
the temperature up to 50% because it rejects cold and heat,
avoiding leaks, leaks and humidity.

It is also used as a sealant in the middle of the setting, for example,
in the creation of scenography or interior decoration.

* Uses in refrigeration *
Polyurethane is used in medium and low temperature chambers. TO
difference of extruded polystyrene, mineral wool and others
products used before they have to be put
an adhesive and join them by plates in the insulations of cameras,
advantages it offers is that it is applied directly on walls, ceilings and
floors with sanitary curves, due to its high adhesion and its sealing
monolithic (which seals in one piece).

Also, with its hermetic seal prevents leaks, cold leakage,
humidity and condensation, resulting in the ideal temperature and
lower energy consumption of refrigeration and freezing equipment
with TIF certification.

TIF establishments comply with national and international standards
of health and hygiene. Among the national standards that must be
To fully adhere are NOM-008-ZOO-1994 and NOM-009-ZOO-1994, the
which set the standard for building and equipping establishments and
process the meat, its reaction is immediate after applying it,
You can even use it the same day, if you have already installed the
Refrigeration equipment.

* Bodyworks *
Another branch of refrigeration is the transfer of perishable products
by bodies specially made for transportation. The
Correct insulation with polyurethane sprayed on the bodies seals
only with the adequate thickness in high and low temperatures with 2 ", 2.5"
and up to 3 "thick for medium temperature and from 4" to 6 "for low
temperatures (the same measurements for cameras), and with the complement of
Thermoking, they fulfill their mission of transporting large distances without
cold loss problems.

* Comfort *
The polyurethane can be applied in ducts, walls or ceilings of
rooms to refuse cold or heat and as a result you can
save electricity because the air conditioning equipment
they will work up to 50% less and like other applications you will save
apart from energy, time, money and effort.

Other advantages of polystyrene are that it has low weight, it is applied
directly on the surface and the results are consequently
immediate.

* Waterproofing *
It can be applied on any type of roof or walls, slab, sheet
of any kind and waterproof, seal or seal. Avoiding leaks
leaks or humidity and also rejects cold, heat or noise for its
thermal and somewhat acoustic properties. If applied on a roof
you need an elastomeric acrylic coating, for protection and that
UV rays and inclement weather can degrade it.

*Process*
If the polyurethane is applied outdoors it must be covered by a
Elastomeric acrylic, since UV rays and other natural conditions
they can degrade it. There must be a good room temperature and the
substrate will have to be completely clean of grease, dust and
any residue that affects the adhesion of the foam.

The sprayed polyurethane is applied by a spray machine
(air pressure) with two suction pumps, each in the
containers of component A and another in component B, which are
separated until going through the heating hoses and reach the
spray gun. By joining together the components make the reaction and give
as a result the rigid foam of polyurethane or polyurethane sprayed,
The final quality of the foam will depend on the equipment used for its
application and the trained personnel that apply it.

* Benefits of insulating with extruded polyurethane *

  * No adhesives are used for placement.
  * The application is monolithic without joints and it is not necessary to join

Polyurethane foam what is it for?

What is expanded polyurethane foam and what is it for?

Expanded polyurethane foam, is one of the main materials currently used in various branches, such as construction of houses, buildings, boats or boats, aircraft, among others.

To understand what it is and how this material works, we will begin by describing its composition.

Polyurethane is a substance that results from the combination of "isocyanate" and "polyol", through a chemical reaction. This combination allows the material to be stretched, crushed or scratched and does not lose its constitution, which makes the polyurethane in a quite resistant material, almost indestructible. The polyurethane can be obtained in liquid, foam or solid mode.

In the case of foam, it is applied in a liquid state and after its application it expands until obtaining its final solid state.

What is expanded polyurethane foam used for?

This material is the main insulator in the construction industry . Thanks to its properties, it is used as a thermal insulator, water-repellent insulation and as an anti-humidity material.

Thermal insulation

Polyurethane foam (EDP) is applied to ceilings and walls to eliminate the transmission of heat or cold (thermal bridge). Additionally, the EDP strengthens the structure, extending the life time of ceilings and walls from 10 to 15 years.

All this generates a great saving in heating and cooling, as well as in maintenance.

Polyurethane foam is an excellent barrier against steam and air, also has excellent resistance to extreme temperatures and high winds.

Water-repellent insulation

The polyurethane foam has a closed molecular structure, which makes it a water resistant material. This property makes it the perfect protector for any type of structure, even for buildings with imperfections or irregular design. In this way the polyurethane foam also provides excellent protection against corrosion and seepage.

• Of course, it also works as a moisture barrier.
• Other uses of polyurethane foam

When used inside walls, polyurethane foam is used to increase the strength and strength of wooden frames, it is also very useful to prevent commercially constructed roofs from rising.

When foam is applied on roofs, it also seeks to increase the resistance to abrasion and is very useful when it is required to build a drain.

It is also used in the home to repair irregularities in the wall surfaces and to insulate and repair PVC pipes.

The expanded polyurethane foam is applied in:

•     Insulation panels
•     Commercial and Residential Insulation: in walls, ceilings, attics and basements
•     Industrial Insulation: Silos, Tanks, Refrigerating Chambers, Refrigerators, Buildings with temperature control
•     Bodyworks
•     Boats, Boats, Floating Dikes
•     Aircraft: to increase the structural strength of the wings

Advantages of expanded polyurethane foam

•     The EDP is friendly to the environment, does not harm the ozone. It contributes to saving energy, so it helps reduce the consumption of fossil fuels and consequently global warming.
•     The polyurethane foam strengthens the structure in which it is applied, making it more resistant to storms, strong winds and vibrations.
•     Seals the structure in such a way that it reduces outside noise.
•     It maintains its properties and physical characteristics over time. There have been cases of more than 30 years of durability of the EDP, without any type of wear.
•     It diminishes the filtration of polluting elements of the air and gases coming from the outside.
•     It decreases the growth of mold and bacteria inside the structure.
•     With the use of the EDP, the cost of heating and cooling the internal areas of the building is considerably reduced. Additionally, by having a structure strengthened by the EDP, maintenance costs are also reduced. On the other hand, the application of the EDP does not require much space, so the cost of construction is minimized.
•     The EDP adheres excellently to all the materials used in the construction. It does not require additional adhesives or a fastening system or method.
•     According to current regulations in the United States and Europe, the EDP is considered a self-extinguishing material, thanks to its properties.
•     It performs the functions of insulation and waterproofing at the same time.
•     It is highly resistant to drinking water, rainwater, seawater, acids, dilute alkaline solutions, gasoline, diesel fuel, propane, mineral oil, exhaust gases and SO2.
•     It is also resistant to the action of insects and rodents.
•     The EDP is a material that is easy to transport, it is not bulky and does not require large storage.

How to use expanded polyurethane foam?

For small or home applications, the EDP can be purchased in aerosol containers. A very practical and easy to use presentation. It is recommended for small-scale work.

At the time of applying the foam, only the following simple steps should be followed:

•     The surfaces on which the foam will be applied must be free of dust, grease and moisture.
•     It is recommended to wet the surface a little before applying the foam, to improve the foaming and to accelerate the reaction.
•     The application nozzle should be placed on the container and shaken several times before using the foam.
•     The EDP must be applied with the container inverted and in ventilated areas.
•     The foam dose is controlled by the pressure on the aerosol valve.
•     Since the expanded foam doubles its volume, it is recommended to apply only the amount of the product, depending on the space or surface to be worked. If it is to fill cracks or joints, only half of the space to be filled must be filled.
•     Once the foam is used, it should be moistened to obtain a better result.
•     In case the amount of EDP is exceeded, it can be cut easily to achieve a clean and level surface.
•     The EDP once dry, can be sanded and painted to obtain a perfect finish.

Presentations of expanded polyurethane foam

For small or home applications, the EDP can be purchased in aerosol containers. A very practical and easy to use presentation. Of course, its content is little, so it is recommended for small-scale work.

For large scale works, the EDP is applied through hoses connected to a larger aerosol mechanism, which is applied on the structure or surface to be protected.

Safety measures when working with polyurethane foam

Polyurethane foam is a very safe working material when the safety standards that are usually indicated on the packaging are met. It is very important that personal protection measures are taken while the EDP is being applied.

You should wear protective clothing or pant, gloves with resistance to solvents and protective mask nose and mouth.

If you have skin contact with the EDP, you should immediately wash the affected area to avoid irritation.

Thermal and acoustic insulation with polyurethane foam

Polyurethane foam is an excellent solution for the thermal and acoustic insulation of homes, leisure facilities and factories. It is a resource increasingly used in the sealing of doors, windows and sanitation, as well as walls and walls.

It has numerous advantages as an insulator because its technical properties are maintained, even in extreme temperatures between -50ºC and 110ºC. In addition, once cured, the foam can be cut, sanded or painted.

Thermal properties of polyurethane foam

Thermal insulation has direct consequences on the energy consumed by a building, the use of adequate thermal insulation is key to achieving energy efficiency in any location, home or office.

It is necessary to act on facades, doors, windows, roofs, etc. to improve its insulation and reduce energy losses due to infiltrations and thermal bridges. Through the polyurethane foam you can save energy.

The structure of the foam and its high crosslinking density leads to characteristics such as excellent insulation, good thermal stability properties and high compressive strength. For example, insulating windows with materials such as polyurethane can reduce heat loss by 50%.

Polyurethane has a very low thermal conductivity, which makes it one of the most effective insulation currently available for a wide range of applications. To this we must add the little space required, since the foam contains only a small part of the volume of solid matter.

Acoustic properties of polyurethane foam

In many homes they suffer from noise from outside or inside the homes themselves. The polyurethane foam is an excellent acoustic insulator and has a great effectiveness in noise absorption and soundproofing of the house.

This material has a great sealing capacity and can be used both in doors and windows, sanitation, walls and walls. Its acoustic properties are mainly due to its sealing capacity, which provides very good results in insulation against airborne noise.

In addition to isolating homes in urban areas or near noise sources, expanded polyurethane foam effectively insulates nightclubs, coffee shops, factories and other places where high noise levels are reached.

Blinker polyurethane foams achieve great results in thermal and acoustic insulation. At the time of applying the foam, it is advisable to protect nearby areas so that they do not stick when they come into contact with them.
