Spray Foam Insulation

Air-tight Weatherization is now offering spray foam insulation.


Spray foam insulation, like other insulation, saves on energy costs and lowers utility bills. Studies by the US Department of Energy show that 40% of a home's energy is lost as the result of air infiltration through walls, windows and doorways. Buildings treated with spray foam insulation insulate as much as 50% better than traditional insulation products.


Insulation properly deployed can be part of a system designed to protect against moisture, which provides the benefit of reducing the chance of harmful mold, mildew and rotting of wood.


In addition to building temperature and moisture control, spray foam insulation is often used to reduce noise. Foam insulation serves as a barrier to airborne sounds, and reduces airborne sound transfer through a building's roof, floor and walls compared to an uninsulated structure.


Spray foam is a chemical product created by two materials, isocyanate and polyol resin, which react when mixed with each other and expand up to 30-60 times its liquid volume after it is sprayed in place. This expansion makes it useful as a specialty packing material which forms to the shape of the product being packaged and produces a high thermal insulating value with virtually no air infiltration.


Spray foam insulation is non-toxic after it has cured. We ask that contractors remain out of the area while we are spraying, and do not return to the building for at least 12 hours after application. A homeowner should vacate the premises for at least 24 hours to allow the chemicals to cure.


Air-Tight Weatherization uses only top quality product from the most reputable distributors in the Northeast. Our foam installers are professionally trained and certified.
