Willseal PF200

A pre-compressed, self-expanding foam joint seal, engineered to perform as a weathertight primary seal in various prefabricated applications. The high-density polyurethane foam self-expands to fill the joint, creating a UV-stable, watertight, and airtight external primary seal. The exterior face of the foam has a pre-cured sealant that allows for the joint material to be color-matched to the facade without an additional labor and material step.
