Willseal® FR-H is a fire-rated, pre-compressed, watertight, UV stable foam, with an integral smoke barrier within the foam body, sound-attenuating expansion joint with a pre-cured, traffic-rated factory-applied sealant applied to the face. FR-H is comprised of a fire-retardant impregnated foam designed to be used in horizontal expansion joints by itself, but it can also be used behind any other expansion joint cover, plate or filler where joint depth allows.
