ENVELO-SEAL™ 2.7 is a two component, closed-cell, polyurethane foam system, designed for spray applications. This foam system offers high compressive strengths, smooth aesthetics, and a broad application temperature window for extended project opportunities.
After installation SPF provides seamless protection by sealing cracks, crevices, and holes while insulating decks from temperature extremes. Polyurethane foam also eliminates condensation preventing mold growth, enhances energy efficiency, and lowers lifecycle costs by providing a low maintenance deck solution.
The ENVELO-SEAL™ 2.7 “A” component is a polymeric disocyanate. The “B” component is a combination of polyols, catalystic agents and non-ozone-depleting HFC-245fa blowing agent.
