Spray Foam Insulation (SPF)
As a designer and 203(k) Consultant, I LOVE how SPF spray foam insulation adheres to any shaped structure - from the roof rafters all the way down to your floor joists, so a protective sealed envelope is formed around your home. This keeps air from penetrating your walls, and stops the dust and pollutants that can come in with it. SPF insulation also helps keep your home cool in the summer and warm in the winter, further reducing your home's environmental footprint. I have worked with this product many times as a designer, builder and inspector, and am continually impressed with its performance.
Spray foam insulation won't sag, shrink or pull away from your walls, EVER. It never needs to be replaced or added to, thanks to its durable nature. Fiberglass batts can sag over time, blown-in cellulose can settle, which leaves sections un-insulated and you'll feel the temperature difference because of it. Spray polyurethane insulation (SPF) completely adheres to wood and sheathing and is rigid; the result is a permanent barrier to heat loss and air entry. Also, the micro-cellular spray foam insulation blocks neighborhood noise, making your home the peaceful healthy haven it was designed to be.
A couple of SPF choices are: Closed Cell (2#) SPF or Open Cell (1/2#) SPF, with a lot of conflicting information out there, but the SPF basics are this:
*R value of 6+/inch for SPF compared to fiberglass batt R value of 3.5/inch.
*Minimizes the transfer of sound.
*Structurally enhances the surface that it bonds to.
*Creates an air-tight seal as it expands into place.
*The cost savings are seen immediately upon application.
*The HVAC system can be downsized, due to SPF’s efficiency.
*Will not settle, shrink, or deteriorate, and it’s guaranteed to retain its R-value and noise-reduction qualities over the life of your home.
Besides its dramatic energy savings, SPF’s are formulated from renewable agricultural resources and uses a state-of-the-art, environmentally friendly blowing agent with zero ozone depletion potential (ODP).
