Counting Carbon: Demand a Better Insulation in Your Next Home
Spray Polyurethane Foam (SPF) insulation is clearly a better insulation choice. The environment, and the impact our decisions have on it, are top of mind these days. We consider environmental impact, using terms like embodied carbon, carbon footprint, life-cycle analysis and use-phase when we make purchase decisions. None more important than our homes. Let’s consider SPF insulation and compare it to fiberglass insulations. Although foam plastic insulations have a higher initial environmental impact than fiberglass insulations, their higher R-values and inherent air impermeability saves additional energy when installed at the same R-value as fiberglass insulations. The ability of SPF to seal wall cavities and provide a vapor, thermal and air control layer eliminate the need for additional vapor retarders and barriers in cold climates. When closed cell spray polyurethane foam (ccSPF) is used, staggered double wall construction and extra-thick wall and roof construction to achieve increased R-value requirements are not needed. You can build with less wood and still have a resilient, energy efficient home
