Willseal® FR/SAF-V 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, factory-applied pick-resistant sealant
applied to the face. FR-V is comprised of a fire-retardant impregnated foam
designed to be used in vertical expansion joints by itself, without the addition
of an intumescent sealant on the foam surface.
