Foam insulation is a green insulation. It does not shrink, settle, or dis-integrate like conventional insulation. Spray foam insulation is the healthy alternative to fiberglass and cellulose. Spray foam does not emit any harmful ozone destroying gases, such as HFCs and HCFCs or formaldehyde.
Unlike fiberglass, when you touch sprayed foam, it will not move or cause skin irritation. Most import-antly, foam insulation does not loose its R-value and spray foam does not support molds or mildew.
Unlike cellulose and fiberglass, foam insulation does not require air circulation to be effective. This allows the foamed area to be draft-free and stops air leakage and heat loss. Therefore, your heating and cooling units will require less usage.
