Polyurethane spray foam, the most common form of foam insulation, was first used in 1940 by the Air-Force. It then became more popular in the 1970’s.
Spray Foam Insulation, is a type of Building insulation which is used for ceilings, walls, pores and seams and other parts of the building to maintain the heat in the cold seasons like winter. This type of insulation is made of resin and other chemicals like polyurethane and isocyanate. When spraying, chemicals and resin spread in the form of foam and then solidate immediately. Spray foams come in two types of open cell and closed cell.
Open Cell Foam Insulation
one type of foam insulation in which the small pores are not sealed completely. Because it is manufactured using less chemicals and in large volume, Open Cell Foam is cheaper than the closed cell. This type is a good insulation to avoid air penetration but doesn’t act well against moisture, that is why it is not recommended for outdoors. The main use of this type of insulation is for the sound and heat transfer reduction.
Closed Cell Foam Insulation
this type is more dense than the open cell and is more compact. The Closed cell foam insulation is suitable for air and moisture insulation. That is why it is used mostly for outdoor project or in ceilings.
Advantages of using Foam Insulation
- Saves Energy Costs
- Based on US Department of Energy, 40 percent of waste of energies is due to air penetration through walls and windows.
- Foam Insulation is almost 50 percent more effective than traditional insulations and protects the building from moisture erosions
- Maintains the building temperature and moisture
- Suitable for Sound Reduction and Noise suppression
Applications
- Insulation of wooden, brick, iron, cement and concrete structures of buildings
- Insulation of heating and refrigeration units in industries and buildings
- Insulation of Hot and Cold-Water pipes, Air ducts and Oil & Gas Pipes
- Insulation of vehicles like trucks
