Spray Foam Insulation : Types And Benefits
While the traditional and older buildings used the fiberglass material for insulation, the new product that is a good alternative is the spray foam insulation. The 2 major components of the foam are Polyol resin and Isocyanate. These two are mixed at the tip of the spray gun. Expanding foam is formed consequently, which is subsequently sprayed into the concrete slabs, roof tiles, through the holes of a cavity and within the wall cavities.
The insulation spray can be applied to different kinds of spray foam systems. One is the 2 component high-pressure system. It is used for the new building and home constructions. Here the spray foam expands very quickly. The other is the 2 component low-pressure system. It is used for the remodeling jobs. These have a slow-rise formula and are also termed as the “injection foam”.
The different types of spray-foams in use today
There two major types of the spray foam used today. These include the open-cell and the closed-cell foam insulation
1. Open-cell foam insulation
Open cell is that type of foam in which the cells do not close completely. As the open-cell foam uses less number of chemicals, it is less costly. The foam acts as a barrier for, but cannot barricade water vapor. It has a sponge-like an appearance and can be used on the interiors walls of a home or building, as it causes a reduction in sound. The foam is not used for the outdoor applications.
2. Closed-cell foam insulation
The closed cell foam has a high density that is much more than the density of the open-cell foam. The compact and smaller cellular structure of the foam can barricade both water vapor and air. The foam is used in the roofing projects and the outdoor applications, but can be used in any area of the home. CPVC pipe fittings suppliers in UAE provide the closed-cell foams along with other equipment and make a home world-class in its architectural built.
Benefits of spray foam insulation
Use of spray foam offers you a number of advantages.
1. Better energy efficiency and greater cost effectiveness
The use of spray foam helps in lowering of the energy bills. As a great amount of energy is lost because of infiltration of air through the doorways, windows, and walls, the use of spray foam can bring in around 40% of savings. Buildings that have the spray foam sprayed on the particular areas have 50% greater insulation capabilities than those having the older insulation products.
2. Protection against the moisture and humidity
Buildings and homes that have been insulated with the spray foams can also protect against humidity and moisture. Hence, the use of spray foam provides for greater control and prevention of the mildew and mold growth. Mold spores and other fungus and bacteria are the cause of health-related allergic reactions. The growth of molds also causes the rotting of wood. The use of spray-foam removes all these abnormalities and makes a home more hygienic and healthy for the occupants.
3. Noise reduction
The use of spray foam also provides for the reduction in noise. The foam insulation acts as a kind of barrier for the air-borne sounds. Hence, the air-borne sounds do not transfer to the roof, walls or floors of a building.
4. Thermal resistance
The “R” valve denotes the thermal resistance of any insulation product and shows how well it will resist the “heat”. The polyurethane foam has been found to have the highest “R” value and is one of the best materials for insulating buildings and homes. The foam can inhibit all kinds of heat transfers including:
5. Conductive heat transfer
6. Radiant heat transfer
7. Convective heat transfer
