Willseal® Seismic SAF-V is a pre-compressed, self-expanding open microcell polyurethane foam impregnated with a hydrophobic, acrylic polymer and coated with a factory-applied pick-resistant sealant. It is designed to provide a watertight, dust-proof, noise-reducing, thermally insulating, and UV stable primary seal for areas that can be easily damaged or vandalized in institutional or other public buildings.
