What is foam insulation? Definition of

Foam insulation is a type of insulation that is sprayed into place through a gun. Foam insulation can be blown on walls, on concrete slabs, on attic roofs. thermal engineering

A semi-rigid panel consisting of polyurethane particles of different densities duly knit, which is used in indoor sound insulation systems.

For its installation you can use metal profiles and subsequent masking with plasterboards, although it achieves greater acoustic effectiveness by using contact adhesive to stick the panel to the wall or ceiling and the same glue to glue the plasterboard to the panel. This product is offered in different shapes, sizes and thicknesses. The thicker the panel, the higher the sound absorption coefficient. There are foam panels of different densities, depending on whether they are intended to be isolated from atmospheric sound or the sound of impact.


foam insulation

Foam insulation is a type of insulation that is sprayed into place through a gun. Foam insulation can be blown onto walls, concrete slabs, attic roofs or under floors to insulate and reduce air intrusion. Spray foam can fill even the smallest cavities, creating an effective air barrier. Foam usually expands to 30-60 times the volume of liquid after spraying it in place. It provides excellent resistance to air leakage (unlike blocks and blankets, which can leave sidelines and airbags, and are superior to some types of loose filler). On the other hand, the cost of foam insulation can be higher compared to conventional insulation and most foams, with the exception of cement foams, release toxic gases when burned.

There are two types of foam insulation:

• Closed cell foam. Closed cell foams are the best insulators. Its high-density cells are sealed and filled with gas that helps the foam expand to fill the surrounding spaces. Closed cell foam is very strong and structurally reinforces the insulated surface.

Available foam insulation materials include:

• cement

• Phenolic

• polysaccharides

• Polyurethane

It is usually made of polyurethane or isocyanate. Cement foams are similar and can be applied similarly but do not expand. These foams have a higher fire resistance compared to polyurethane or isocyanate foams.

Attic insulation - roof insulation

A very important source of heat loss from the house is through the roof and attic. Attic insulation is a thermally insulated protective interior coating procedure that involves the use of glass or rock wool, polyurethane foam or phenolic foam. It should be noted that there is a difference between sloping roof insulation and flat roof, and there is a difference between cold or warm overhead insulation. Cold roof insulation requires insulation at the beam level to prevent heat from escaping through unused roof space. Warm insulated roof between and under ceiling beams.

The purpose of roof insulation is to reduce the overall heat transfer coefficient by adding materials with low thermal conductivity. Roof and attic insulation in buildings is an important factor in achieving thermal comfort for its occupants. Roof insulation, as well as other types of insulation, reduce unwanted heat loss and also reduce unwanted heat gain. It can significantly reduce the energy requirements of heating and cooling systems. It must be added, there are no materials that can completely prevent heat losses, heat losses can only be minimized.



Foam insulation feature

When you don't use foam insulation on the roof of buildings, 35% of the heat goes away. Even if you burn natural gas to the end, your heating rate will be 35% lower. The benefit of foam insulation does not only apply in winter. It also prevents the high temperature on the roofs in the summer from being reflected in the dwelling. The heat accumulated on the surface will cause a decrease in humidity and humidity. Don't use spray foam only on surfaces. It is used on open terraces and exterior facades of apartments, as well as on ceilings.

Those who don't use foam but want thermal insulation with regular materials get more tired and spend more. More products are used when insulating with ordinary insulation materials. Insulation board, adhesive, mesh on the boards, plaster and paint on top will be required. Successive operations will waste time and power. Ordinary insulation material is a load on the building. Overcrowding is also a problem. Nor does it make 100% insulation.

Foam insulation date

Those looking for 100% insulation do their job in a short time using the product Foam Insulation Spray. The products which are economical are widely used among the public. It is also known as pressing foam, mounting foam, spraying polyurethane, filling foam. Foam, which is of great use to structures, dates back to 1848.

It was first produced in 1848. The first use was carried out by the German chemist P. Hoppe and colleagues in 1951. Today, it uses approximately 20 million tons. Spray with a high pressure sprayer. Product characteristics are briefly as follows.

• After spraying, it swells approximately 30 to 40 times on the surface being pressed.

• It does not leave gaps on the surface where it is swollen.

• It closes without interruption.

• It is one of the rare materials that make 100% insulation among the thermal insulation materials in our country.

• It transfers heat late, completely destroys the thermal bridge, does not contain moisture, dampness and mold in its content.

Spray foam should be used if it is not desirable to have an attachment in the insulation application. It is extremely easy to apply the product, which is often used in ceiling insulation. When applied by professional hands, the result is flawless. Before spraying the foam, at least 4 materials for sound and thermal insulation had to be used. Only four components combined to replace spray foam.

Foam insulation is more practical than older applications. No labor and no transportation costs. No need to spend any Egypt

Additional deaths to work in demand. Foams with maximum thermal insulation are for life. It provides the same insulation for many years. It does not contain substances harmful to human health and the environment. No special adhesive needed to stick. Resists for approximately 4 hours during a fire. The foam, which is not a load on the building, sticks once it is squeezed.

Foam insulation areas of application

Solitude is a necessity wherever life takes place. Therefore, the area of ​​​​application of spray foam, which is effective in heat and sound insulation, is wide. Among the fields to which it applies are the following:

• On floors and ceilings

• On the reverse ceiling and wood

• Termit ceilings and table sheets

• In animal farms and fattening

• In cold storage

• Carpet drying rooms

• blind facade buildings

• In wooden houses

• A mosque in the cladding in the dome

• Paint inside the car


What are the types of foam insulation?

urea-formaldehyde insulating foam

Urea-formaldehyde foam was used in homes during the 1970s and early 1980s. However, after several health-related cases in the courts due to inadequate facilities, UF foam is no longer available for residential use and has been discredited due to formaldehyde emissions and shrinkage.

It is now mainly used for masonry walls in commercial and industrial buildings.

UF Foam Insulation uses compressed air as a foaming agent.

Nitrogen-based UF foam can take several weeks to dry completely.

Unlike polyurethane insulation, UF foam does not expand as it dries.

Water vapor can easily pass through it, and it decomposes at long temperatures above 190°F (88°C). UF foam does not have flame retardant properties.
