Willseal Color Coreseal-H: Closed Cell Foam

Willseal Color Coreseal-H is a lightweight, closed-cell foam coated with a traffic-grade factory-applied sealant. It is designed to provide a watertight, dust-proof, airtight, noise-reducing, thermally insulating and UV stable primary seal that does not require invasive anchoring for installation. Questions? Contact Us.

Willseal Color Coreseal-H is a dense, closed-cell foam for larger movement joints. It has a traffic-grade silicone skin on the exposed face which provides resistance to gasoline and oil. Due to its strong closed-cell structure, it has excellent compression, tension and shear capabilities. It is installed with epoxy that permanently bonds the Color Coreseal-H in place.
• Allows for up to 50% (±25%) movement
• Accommodates rapid rates of joint movement
• Supplied uncompressed 25% over the mean joint size as a standard
