Foam Attic Insulation

Spray Foam vs. Rigid Foam

FoamAtticInsulation

When deciding which type to choose, our many years of experience have shown that both are important and effective when upgrading your attic. If following the guidelines of the Department of Energy, it is possible to cut your heating and cooling expenses in half.

 

Spray Foams Effectiveness

Spray foam is applied directly against the plywood base of the sheathing on the roof, between rafters and studs in the attic. Save hundreds of dollars annually while enjoying increased comfort.

 

Picking Up where Fiberglass Falls Short

Most people see fiberglass at the hardware store and notice that it is used most in homes and assume that it is the best quality and most efficient material to work with. This, however, is not true. Fiberglass has a make-up that is soft and fluffy like a pillow.  This make-up, however cannot stop the movement of air. Foam insulation, on the other hand, does not get pressed down over time. This leads it to keep its R-value over time. Fiberglass gets compressed and saturated over time and loses its effectiveness. Two kinds of foam can be installed in an attic: Spray foam and rigid foam. First Spray Polyurethane Foam (SPF) is usually applied to the underside of the plywood under the roof, called the sheathing. This fully seals and insulates the roof.  Rigid Foam, is another option to insulate the roof, which can be placed between the rafters or directly below them. Both methods create an “Envelope” which insulate the attic from the exterior.

 

Making your attic an Asset with Foam Insulation
Using foam insulation for and Attic insulation upgrade is an investment for those who want to use their space for storage or to make a once unused attic into a living space. It is also a wise decision for homes with extensive ductwork or HVAC equipment. Both of these will work with increased efficiency if they are insulated.
