Willseal® Seismic HS

Pre-Compressed Horizontal Expansion Seal

Willseal® Seismic-HS is a pre-compressed, self-expanding open micro-cell
polyurethane foam impregnated with a hydrophobic, acrylic polymer and
coated with a factory-applied silicone sealant. It is designed to provide a
watertight, dust-proof, noise-reducing, thermally insulating, and UV stable
primary seal that does not require invasive anchoring for installation.
