Spray-based polyurethane applications
The insulation and waterproofing prevent leaks, cracks or
humidity and can be applied on various surfaces.
When a thermal insulator is used correctly, it can be obtained
Energy savings of up to 40%
With an adequate thermal insulation can be achieved significant
energy savings, as well as avoid moisture in the walls or molds in
metals. An insulator, allows life to be more pleasant in the
environment that surrounds us, when applied outdoors should have
always a coating (acrylic, elastomeric) to avoid
degradation due to UV attack and other adverse environmental conditions.

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
plates as with other products.
* Under weight.
* Fast application (10 to 1000 m ^ 2 depending on the thickness).
* Immediate results (low temperature on the same day of application).
* Raincoat.
* Anticorrosive (for not having nutritional value).
* Ecological (accepted by FIDE, ONNCCE and INFONAVIT)
* Cost-effective, it is quoted in m ^ 2 per inch of thickness.
Also other derivatives of polyurethane sprayed and widely used in the
The means of refrigeration are: polyurea, a rigid finish,
anticorrosive, resistant to high and low temperatures, resistant to
various chemicals, shock and heavy traffic if applied in
floors or walls. You can do sanitary curves, it's compatible with
Drinking water, monolithic, waterproof, antifungal, non-toxic and is
Used as a finish on walls, roof and floor of cameras, tanks and
swimming pools, among others. Another rigid finish used in walls and roof
cameras is the elastomer, totally washable with TIF certification, it
You can do sanitary curves.
Before choosing the insulating material, you must take into account
temperature of the place where the house is located, its size and the
conditioning equipment that is used, since these can be seen
harmed by using an incorrect insulator.
