According to the American Chemistry Council (ACC), Spray Polyurethane Foam (SPF) insulation can increase the energy-efficiency of a home by creating a sound building envelope.
What does this mean?
A sound building envelope can shield a home’s living areas from the outdoor environment. Homes can lose nearly 40 percent of heating and cooling energy through cracks and gaps in the building envelope.
SPF can act as an effective barrier against air leaks in common spots, such as walls, attics, floors, rim joists, crawl spaces, as well as areas around doors and windows. Sealing these common air leaks and improving the building envelope can help reduce a home’s energy consumption, resulting in lower greenhouse gas emissions and utility bills.
But Wait, There’s More …
Employing building envelope measures – like SPF – can help a home use less energy, regardless of the generation source, and allow builders and homeowners to use smaller HVAC systems.
Additionally, SPF is valued for delivering consistent performance and savings, and for being easily incorporated into a home or building during construction. Why? Because code officials can inspect the building envelope to give people confidence that the home is built to comply with code requirements and will perform as expected.
Finally, an efficient building envelope can provide many benefits that extend beyond energy savings. Protecting the home from the outdoor environment can improve the building structure’s durability. In fact, some types of SPF insulation have proven to enhance the strength of walls and roofs, as well as guard against moisture intrusion (think mold growth).
