The Key to Building Energy Efficiency? A Sound Building Envelope
Spray polyurethane foam (SPF) insulation can increase the energy-efficiency of a home by creating a sound building envelope, which shields the home’s living areas from the outdoor environment. Homes can lose as much as 40 percent of heating and cooling energy through cracks and gaps in the building envelope. SPF acts as an effective barrier against air leaks in common spots including walls, attics, floors, rim joists, crawl spaces and areas around doors and windows. Sealing such common air leaks and improving the building envelope can help reduce a home’s energy consumption, resulting in lower greenhouse gas emissions and consumers’ utility bills.
