Insulation Contractor is made up of tiny pockets that create barriers to air movement, sound and heat energy. It is highly effective, even in difficult to reach areas of your home. It can also offer design flexibility by conforming to your home’s unique structure.

Maintaining Your Spray Foam Insulation

Foam is a green building product that can significantly reduce your heating and cooling costs. It does this by creating a tight air barrier that dramatically improves the R-value of your house. The old R-value system only considers conductive heat transfer while spray foam is able to seal from both conductive and convective transfer. Oak Ridge National Laboratory tested spray foam and found that homes insulated with spray foam were up to 50% more efficient than those using fiberglass insulation.

Before insulating with spray foam, it is important to prepare the area by cleaning thoroughly. It is also recommended to moisten the surface so the foam will adhere well. After the surface is clean, a professional will set up an insulated rig to spray the desired area. This rig is equipped with a machine that blends 2 types of composite materials, polyol and isocyanate, together to create the foam that is sprayed at the gun.

The chemicals used to make this foam are toxic and need to be handled carefully. Isocyanates are irritants to the eyes, nose and gastrointestinal tract. Exposure to isocyanates can also lead to chemical bronchitis, which is a severe breathing disorder that affects the entire respiratory tract. A new generation of spray foam uses low GWP blowing agents that drastically reduces the hazard.
