Projected polyurethane: an optimal insulating material

Polyurethane systems are one of the most used materials for the insulation of buildings due to their excellent properties . Its structure guarantees the air tightness of the buildings, the impermeability, the absence of joints as well as a low thermal conductivity, which gives the buildings a great thermal behavior and makes them more energy efficient.

Synthesia Technology is a manufacturer and distributor of   polyurethane systems   for building and industry. The main application of these systems is through projection. The result is known as   Projected polyurethane or projected polyurethane foam .

Origin of the projected polyurethane: how is it obtained?

The rigid polyurethane foam is obtained when two chemical products, a dissociant and a polyol, are mixed in the presence of suitable catalysts and activators.

In the application of rigid foam by projection for a function of thermal insulation in the construction sector, the mixing takes place in a small chamber located in the projecting gun.

Once the components are mixed, the heat released during the reaction is used to vaporize the blowing agent, which is the cause of the transformation of the mixture into foam with an approximate volume of 30 times the volume of the components in liquid state.

It is important to know how to correctly apply the projected polyurethane , taking into account a series of factors that range from atmospheric conditions   and the   machinery adjustments   up to the types and forms of the applications.

In this video you can see in detail how the rigid polyurethane foam is formed from these two components:

Properties of projected polyurethane foam

Thermal properties

The projected polyurethane has a high insulating capacity due to the low thermal conductivity of the foam gas in its closed cells, which can be placed at 10ºC = 0.022 W / m · K according to the UNE 92202 Standard, although this value rises slightly with the the passage of time until finally stabilizing.

After 9 months of aging, it is considered that the value is 10ºC = 0.028 W / m · K according to UNE 92120-1, which represents a 25% improvement with respect to the average of the other products used in thermal insulation (for example mineral wool or extruded and expanded polystyrene foams).

This material presents a great resistance against the effects of the passage of time and has a long useful life, remaining without deteriorating for more than 50 years.

The rigid polyurethane foam obtained by projection is the most efficient insulating material, since it requires a minimum thickness to insulate the same as other insulating materials . This good thermal behavior in relation to the thickness supposes an economic benefit, since no useful surface in a building is wasted.

The combination of thermal and economic benefit has been one of the main drivers of market development of projected polyurethane, which is in full expansion, as we observed on the IPUR website .

Properties facing water

The Technical Building Code seeks to limit the risk of the inadequate presence of water inside buildings and in their enclosures. As stated by the CTE, intermediate continuous coatings are one of the best alternatives to meet these impermeability requirements.

The projected polyurethane complies with the requirements established in DB-HS1 for insulation materials related to sealing, cracking resistance, adhesion, permeability and physical and chemical stability .

With a continuous coating like the projected polyurethane of closed cell, it is not necessary to render plaster as the material itself meets the requirements of impermeability. This supposes an economic benefit and of space, since the necessary thickness is smaller.

With regard to humidity, in most cases the projected polyurethane guarantees the absence of interstitial condensation, due to the relative values ​​of humidity and its density. This characteristic allows the transpiration of the enclosure, which avoids pathologies related to the internal health and, at the same time, guarantees the durability of the building.

Properties in front of the air

An optimal insulation system must combine the thermal properties with the good behavior against air. That is to say, it must guarantee the watertightness of the building .

Air tightness is one of the concepts around which passive houses revolve, allowing savings of up to 80% compared to a traditional building.

The projected polyurethane is a continuous insulation : this continuity forms the barrier against air that allows the envelope of the building to have an adequate seal.

Properties in front of the fire

Polyurethane systems with high fire resistance are totally safe insulation in buildings, both structurally speaking and for the safety of their occupants. You have to knock down the   false myths that exist around this type of isolation through the various tests that have been carried out.

ANPE conducted a comparative study of the reaction to fire of constructive solutions of polyurethane and mineral wool in final condition of use . In the article you can download the videos of the comparative tests to know firsthand the results.

Projected polyurethane systems with insulating function

As we have pointed out above, Synthesia Technology is a manufacturer and distributor of polyurethane systems for building and industry.

In the case of projected polyurethane, our polyurethane systems applied to the building focus on three functions: thermal insulation, acoustic insulation and anti-radon barriers .
Polyurethane sprayed as thermal insulation

We can say that the projected polyurethane is fashionable and this is largely due to its functions as a thermal insulator. Some examples of applications of our projected polyurethane systems with thermal insulation functions:

•     Isolation of floors .
•     Waterproof ventilated facades .
•     Rehabilitation of covers .

Polyurethane sprayed as acoustic insulation

We have a range of projected polyurethane systems that, in addition to the function of thermal insulation, have excellent acoustic characteristics. You can read more about it at:

•     Insulation for floors between floors .
•     Acoustic insulation for floors .

Polyurethane sprayed as an anti-radon barrier

Our newest polyurethane system combines the function of thermal insulation with that of anti-radon barrier. The new ECO superheated polyurethane projection is presented as an efficient solution against the danger of radon gas in buildings.

This anti-radon barrier is optimal both in new construction and in buildings already built.

The abovementioned are just some examples of our polyurethane systems designed for building . We have a wide variety and a specific line of polyurethane for industrial applications.

Insulation with polyurethane foam, a protective layer

Efficient. Polyurethane foam is an insulating material that also contributes to energy savings. Characteristics, properties, applications and economic advantages.

The energy efficiency of architectural works is key to achieve direct savings through the reduction in consumption in air conditioning (either in the initial investment or in daily consumption). In addition, this attribute allows to generate greater comfort at a lower cost.

The only way to achieve this goal is through efficient thermal insulation. In this sense, among the possibilities currently presented by the market is the rigid polyurethane foam, which provides a concrete solution to the high demands of sustainable projects.

Due to its high thermal effectiveness, this material has marked advantages in the price-quality ratio compared with other insulators. This has made it become a leading product, say from the company Hi Tec Polyurethane.



HIFORT 10 Inch Memory Foam Mattress Queen with Medium Plush Feel - Non Toxic 60x80 Comfy Foam Mattress Colchon Queen Size- Fit for Bedroom Bunk Trundle Boxed Bed - Compressed in a Box

Main features

Multiple conditions make polyurethane foam a highly chosen material when selecting a product for the insulation of homes. Among the main virtues that are recognized, are:

• · Thermal insulation: as it has a very low coefficient of thermal conductivity, it facilitates significant savings in the use of energy for air conditioning. In this way, it favors sustainability and promotes environmental care.
• · Water-repellent insulation: protects from moisture. In addition, placed in the correct densities, guarantees impermeability.
• · It is good acoustic insulation: it generates a barrier against the annoying noises of the environment.
• · Anti-condensation: forms a monolithic layer without joints, solving the problem of internal rain.
• · Resistant to fire: it is a material qualified as self-extinguishing.

Properties

But that is not all: beyond its own characteristics, in terms of versatility at the time of applying it and its result in time, a series of properties is attributed to it, among which are:

• · Ease of application for its spray system, which reduces the cost of labor and the time of installation.
• · Application in construction sites or finished buildings.
• · Application "in situ".
• · Prolonged duration
• · Excellent adhesion to all types of construction materials.
• · It is continuous: it eliminates thermal bridges, with the consequent saving of energy.

Application

The application of polyurethane foam in situ by spray system provides excellent thermal insulation and anti-condensation, which guarantees a perfect waterproofing. This is due to the high density of the material, in which a barrier is achieved that prevents the penetration and filtration of water.

One of the most important resulting benefits is maximum insulation with minimum thickness.

Even in the case of in situ projection (normally used in interior and exterior facades), other performances can be added: high adhesion, effective adaptability, impermeability, continuous application without joints or thermal bridges.

Its adhesion occurs on any material and, once placed, does not crack before changes in temperature or expansion.

Where can you apply

In family homes, you can apply on the roof or below it, whatever your material. It can also be used on walls, where good results are achieved.

It is highly recommended in double wall systems, as an effective insulator against moisture.

However, its use has also been generalized in large-light houses, where it reaches optimal levels of temperatures over large areas.

These characteristics have led to its use being extended to animal breeding sites and also to cold storage chambers, storage tanks and silos and, in general, to industries of all kinds.

Economic benefits

Technicians and specialists also highlight a series of economic advantages. For them, the application affects construction costs and housing services.

• · Significantly reduces the costs of heating and / or cooling environments.
• · Polyurethane insulation requires very little space, reducing construction costs.
• · The polyurethane foam will not yield or deform over time, which makes it an excellent long-term investment.

What uses does polyurethane foam have in construction?

Many will wonder what exactly polyurethane foam is used for when building. The answer is very simple: it is one of the most powerful thermal insulators on the market. It is obtained from the mixture of two chemical components: Isocyanate and Polyol. Due to its durability, high resistance and easy application, it has become one of the essential materials to keep buildings cold or warm according to the season of the year.



Zinus 12 Inch Gel-Infused Green Tea Memory Foam Mattress, Queen

Introduction to the uses of polyurethane foam

There are two ways to apply the rigid polyurethane foam under construction (provided that the current regulations regarding the thickness required for each construction situation are respected). These are: - projecting its two components simultaneously on the surface in question ( projected polyurethane )
- mixing both chemical elements before application General attributes One of the most important resulting benefits is maximum insulation with the minimum thickness . Even in the case of "in situ" projection (normally used in interior and exterior facades), other performances can be added: high adhesion, effective adaptability, impermeability, continuous application without joints or thermal bridges, double quality certification (product and installation).

Thermal and waterproof properties

The insulating capacity of polyurethane foam comes from the low thermal conductivity of the gas emitted by its closed cells. This feature places it above all other products of this type. It should be noted its resistance over time and its long duration without deterioration (which may exceed fifty years). Its reaction to water There are many properties of this material that make it really waterproof: tightness, adhesion, physical and chemical stability, permeability and resistance to cracking. When placing the polyurethane foam as an intermediate continuous coating, no plaster is required (mortar coating), which is a great economic benefit.

Attitudes towards fire and humidity

Once the work is finished, the polyurethane foam will be placed under ceilings, walls, walls and floors. Bearing in mind that polyurethane is combustible material, such surfaces must be composed of fire resistant components so that there is no danger. Its reaction to humidity This product is waterproof, which allows the transpiration of the enclosure. The latter prevents all kinds of drawbacks that drag moisture, such as fungi. Finally, it is essential to highlight the acoustic properties of the foam (acoustic foam). Being a light material and high density, if combined with other materials, it is very effective to eliminate resonances, noise, and everything related to the transmission of sounds. Undoubtedly, polyurethane foam is preferred by many architects when choosing a quality insulation.

Insulation with spray polyurethane foam

Are you looking for a way to differentiate your business? Get closer to greener building practices such as the use of polyurethane foam insulation that offers greater energy efficiency while reducing installation costs.

Insulation with polyurethane foam in aerosol acts as an insulator and also as an air sealant in residential structures. The insulation is spread between the nooks and crannies of the houses - climbers, beams, crossbars - and it expands to fill the space. As a result, in one step the cavities in the walls are filled and the air holes are sealed.



LUCID 10 Inch Gel Memory Foam Mattress - Medium Feel - CertiPUR-US Certified - 10-Year U.S. Warranty - Twin XL

The two types of filling foams - open cell (isocyanurate) and closed cell (polyurethane) - are excellent thermal insulators. Closed cell foams generally weigh more and have a higher R value than the open cell foam.

Once dry, the excess foam is removed with a handsaw.

However, most polyurethane foam insulation products have R-value ratings per inch twice that of insulation rating on fiberglass blankets.

Applied in liquid form, the sealing foam insulation contains a polymer (such as polyurethane or modified urethane) and a foaming agent.

Certified installers, who are trained to use the equipment and chemical mixtures, spray the liquid preventing excessive spraying, and give the walls a proper finish.

Once the insulation is sprayed with polyurethane foam, it expands in a matter of minutes to fill the cavities. After it dries, the excess foam is cut out and a thermal barrier is installed, usually panels of compressed material (drywall). Because the expanded polyurethane insulation does not shrink, buckle or biodegrade, it helps minimize problems once the wall cavity is covered.

The sprayed foam completely fills the angular beams of the roofs.

Benefits of polyurethane foam

The ability to expand in narrow areas makes polyurethane foam an ideal product for insulating steel frame structures and for filling - areas in tiny places such as window lintels, small uprights, beam flange areas, around of electrical distribution boxes and other inputs- where cutting fiberglass fillings of the appropriate size is often difficult and labor-intensive.

By blocking wind and air filtration, foam sealant generally eliminates the need for additional techniques to seal tightly, such as caulking, applying drainage membranes and vapor barriers and taping joints.

Another benefit is the ecological composition of polyurethane foam. All polyurethane foams consist of resins derived from agriculture and do not contain any type of hydrochlorofluorocarbons (HCFC) that are harmful to the earth's ozone layer. Nor do formaldehyde emanate - a potentially harmful volatile organic compound.

Although insulation materials with polyurethane foam may initially cost more than traditional fiberglass fill insulations, savings increase over time. First, the use of polyurethane spray foam insulation has a competitive cost because it reduces construction time.

Second, it reduces the number of specialized contractors needed for the job. Finally, the superior value R of the foam offers greater energy efficiency so that smaller cooling and heating systems can be installed. All these three reasons - higher productivity, energy savings and environmental protection - provide benefits to the contractor and, in the long run, also to the home buyer.

Process of certification

The NAHB Research Center administers the Insulation Contractors Certification (ICC) program, evaluating participating contractors externally. The Research Center joins with Certain Teed Corp., which supplies the Installer Quality and Training Systems for the program.

Certified installers are reexamined every two years and are subject to visits to workplaces conducted by the Research Center's auditors.

"Builders are smart to hire contractors who participate in a program evaluated by a name they can trust," says Michael Luzier, president of the NAHB Research Center. "In such a competitive current labor market, nobody has the time or money to pay for a repair visit for a job badly done."

How to correctly apply polyurethane foam

Benefits of polyurethane foam for acoustic insulation

Like many of the great discoveries of the 20th century , polyurethane foam appeared by chance. In 1937 Dr. Otto Bayer was looking for a new way to synthesize fibers for the textile market after the appearance of nylon.

In addition, with these investigations, we sought to find a new way of producing plastics much easier and with fewer by-products.

Contrary to what was pursued with the investigations, the results did not give the expected result. No fibers were obtained, which was achieved was a foam that thanks to the formation of carbon dioxide as a byproduct formed pores in it.



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

Polyurethane foam The years after the discovery of polyurethane foam, were dedicated to find applications where you could use this new material. Among which stood out on the one hand the thermal and acoustic insulation , boat and aircraft construction, prosthesis or shoe soles.

It was not until the mid-1950s that the manufacturing process of these foams became industrialized and commercialization began. For the use of polyurethane foam as a thermal and acoustic insulator we will have to wait until the 60s when its characteristics were put in the foreground as an excellent thermal insulating material.

In 1967, with the manufacture of blocks of rigid foam there is a great impulse for the widespread use of thermal insulation panels for polyurethane foam buildings .

The use of this material as a thermal insulator has proven to be very effective due to its excellent behavior, preventing heat losses in the home, with consequent savings in the energy bill.

The polyurethane foam can be used in different ways, either directly projecting it in the area we want to isolate , or using formed sheets or prefabricated panels.

Depending on the way we use this insulating material your application will need some requirements or others. In the case that we decide to install polyurethane panels , the only requirement will be the previous cleaning of the surface that we want to insulate to ensure the correct thermal and acoustic insulation .

If on the contrary we choose to project the polyurethane foam on the area that we want to thermally or acoustically insulate, in addition to cleaning it, we should not completely coat it with this insulating material, since once projected, its size increases from 2 to 5 times after a brief time frame. Once dry, the remaining that protrudes from the area that needs thermal insulation , can be easily cut with a cutter or other cutting instrument.

Advantages of insulating with polyurethane foam

This thermal and acoustic insulation material has a series of properties that make it a good option for the general thermal insulation of the house of which we highlight the following;

•     It has very good thermal behavior supporting a wide variation of temperatures. Maximum insulation capacity with very little thickness. An insulation of 1 or 2 cm is comparable to a stone wall half a meter thick.
•     Being a foam, it is a lightweight material , has little weight, and is especially recommended for use as thermal insulation on roofs.
•     Water-resistant and fire-retardant material , prevents the passage of moisture inside the house so it can be used in the exterior areas of the house and protects from fire.
•     If used in the form of panels, they are easily handled and cut and perforated easily.
•     They can be painted and glued without the need to treat the insulating material
•     Easy installation The polyurethane foam is installed simply and quickly.
•     It can be used in areas of difficult geometry . The polyurethane foam is attached to all types of surfaces.
•     Extends the life of the building and achieves energy savings. The installation of any thermal insulation makes homes gain energy efficiency and this leads to a great saving of energy and money seeing the building's energy bill reduced.

The thermal insulation by means of some of the insulating materials that the market offers is a solution to recover the comfort inside the house. From Ecogreen we can offer you a wide catalog of insulating systems and materials as well as the necessary advice to know which is the right one to install in your home.

Advantages of polyurethane as thermal insulation (with practical example)

The high insulating capacity of polyurethane is not achieved in the construction with any other commonly used insulating materials. This special feature is due to the structure of small cells that form the foam, and the composition of the insulating gas occluded inside those cells.

Thanks to its low thermal conductivity , polyurethane reaches the thermal insulation values ​​required in the CTE with the minimum thickness, which allows to preserve a larger living area, with the consequent economic benefit.

On the other hand, if polyurethane thicknesses similar to other materials are incorporated, greater thermal resistance and greater energy savings are achieved , which also results in an economic benefit for the user.



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

The thermal conductivity of the polyurethane depends on several factors, such as the percentage of closed cell , the size of the cell, the foam gas used, or the insulation thickness installed. In addition, the thermal resistance depends on the conductivity and thickness of the installed insulation. For this reason, the manufacturers of polyurethane systems declare the thermal resistance in the CE Marking and the Declaration of Performance through a performance table.

The thermal conductivity and the thermal resistance of the projected and injected polyurethane are declared by a performance table according to the thickness.

The best value of thermal conductivity, together with the tightness, absence of joints or holes, adaptability to any substrate and adhesion make the polyurethane projected the most effective insulation.

Robust thermal conductivity value

The thermal conductivity value of polyurethane foam is very robust against the effects of aging , such as the presence of moisture, dirt, lack of air tightness, the presence of holes in the insulation, deterioration of the same or the lack of physical integrity.

Humidity

The thermal conductivity of a wet insulating product is greater than that of a dry thermal insulator, in the same way that a wet sweater holds less than a dry sweater. It will be necessary to prevent an insulation from absorbing water, since a thermal insulation with a water content of 1% by volume can increase its thermal conductivity between 75% and 105% (Building Regulations for the Conservation of Fuel and Power. Assessment, BRUFMA). The projected closed-cell polyurethane has water impermeability .
Decrease in insulating capacity due to water.


Dirt

The thermal conductivity will be seriously damaged by the presence of dirt inside the insulation, so it will be preferable that the product used maintain its thermal properties regardless of the dirt present in the environment. The closed cell structure of the projected polyurethane prevents the entry of particles inside it.

• Decreased insulating capacity due to dirt
• Lack of air tightness

If the main sheet is made of a brick factory, or a lightweight block, it is possible that there is air infiltration from the outside to the interior of the chamber. The polyurethane will prevent these infiltrations of cold air . The movements of air through a non-watertight insulation or with joints can reduce the insulation values ​​up to 40% ("Experimental and theoretical investigation of the influence of natural convection in walls with slab type insulation" and "Sensitivity of insulation wall and ceiling cavities to workmanship ").
Decreased insulating capacity due to air infiltration.


Presence of gaps in the insulation

The joints, the upper and lower termination, the blind holes, etc., could produce convection currents that would communicate both sides of the insulation and reduce their effectiveness. It will be necessary to ensure the total absence of gaps in the insulation, since the presence of gaps in 6% of the insulated surface would cause an increase in thermal conductivity of 30% (Retrofitting: Wall insulation and roof spraying, BRUFMA conference 2004). The projected or injected polyurethane, being a product adhered, in continuous and without joints, will not be harmed by this effect.

• Decreased insulating capacity due to joints

Deterioration of the insulation

In all the insulating products, the installation is the most important aspect so that the final product reaches all the declared thermal performances. A bad installation could cause take-offs and removals that will seriously damage the effectiveness of insulation.

• Decrease in insulating capacity due to deterioration.

Physical integrity

The passage of time can lead to settlements and compaction in inconsistent products. The projected or injected polyurethane, being a rigid material , can not suffer these effects.

• Decrease in insulating capacity due to settlement
• All these effects can occur in combination

Great decrease in insulating capacity due to the combination of different effects.

Being the polyurethane projected or injected a continuous product without joints, there is total absence of thermal bridges caused by joints, overlaps, or encounters with the floors, and it is very easy to treat thermal bridges integrated in the facade as pillars, boxes of blind and contour of holes.

Thermal resistance

From the declared conductivity value, and knowing the applied thickness, the thermal resistance can be known by applying the following relationship.

• R = e /?

Where:

•     R is the thermal resistance, in m² · K / W
•     e is the thickness, in m
•     ? is the thermal conductivity, in W / m · K

Thermal Resistance value, in m² · K / W, depending on the conductivity and thickness. For intermediate values, it can be interpolated.

• polyurethane values
• Equivalent thickness

The equivalent thickness of an insulating material is that which equals the thermal resistance of another insulating material of known thickness. That is, it is that thickness that makes both materials have the same insulating capacity.

To calculate the equivalent thickness it is necessary to equalize the thermal resistances of both products.

• R = e1 /? 1 = e2 /? 2

Where:

•     R is the thermal resistance, in m² · K / W
•     e1 is the thickness of material 1, in mm
•     ? 1 is the thermal conductivity of material 1, in W / m · K
•     e2 is the thickness of material 2, in mm
•     ? 2 is the thermal conductivity of material 2, in W / m · K

Example of thermal behavior of polyurethane as insulating material

We want to establish the equivalence between a given product of thermal conductivity 0.036 W / m · K and thickness 80 mm and the projected polyurethane of conductivity 0.028 W / m · K.
Starting data:

•     e1 Thickness of the given product: 80 mm
•     ? 1 Thermal conductivity of the given product: 0.036 W / m · K
•     ePU Projected polyurethane thickness
•     ? PU Thermal conductivity of the projected polyurethane: 0.028 W / m · K

polyurethane example

That is to say: replacing 80 mm of the given product with 60 mm of projected polyurethane, we will be able to equalize the thermal resistance.

    Conclusions of the use of polyurethane as thermal insulation material
