Extruded Foam Insulation Sill Seal

WEATHERMATE™ SILL SEAL Foam Gasket is a flexible polyethylene foam gasketing strip that can help reduce air infiltration between a concrete foundation and sill plate, around windows and doors – and even between floors. The closed-cell polyethylene foam compresses to seal gaps in irregular surfaces, helping reduce air infiltration for a tighter building envelope and enhanced energy savings. It provides excellent and enduring resistance to water and water vapor.

WEATHERMATE™ SILL SEAL Foam Gasket is part of the complete WEATHERMATE™ Weather Barrier Solutions lineup from Dow – products designed to enhance the performance of the building envelope.

WEATHERMATE™ Sill Seal Foam Gasket also helps reduce air infiltration in commercial applications, including the THERMAX™ Wall System
