WALLTITE®

WALLTITE® is a high-performance, closed-cell spray polyurethane foam (SPF) insulation that creates a seamless insulating air barrier to help improve the energy efficiency, comfort, and durability of homes and buildings. Spray-applied as a liquid, WALLTITE® expands and adheres to most substrates, flowing into cracks, joints, and hard-to-reach areas to form an airtight seal. Its closed-cell structure also adds rigidity and provides a vapor control layer to resist condensation, supporting long-term building performance. WALLTITE® easily seals corners and transitions, as well as areas around pipes, wiring, and other openings, helping to reduce air leakage and moisture intrusion.
