Fire rated wall expansion joint, Emshield WFR (Wall, Fire-Rated 2/3-Hours) is a watertight, fire-rated, dual-sided primary seal for repair, retrofit, and new installation in structural expansion joints and construction joints in vertical plane wall and head-of-wall applications.
Emshield WFR is a 2/3-hour UL-certified fire barrier and preformed alternate to fire caulk and fire stop materials.
Emshield WFR features dual-sided silicone sealing surfaces adhered to a fire-retardant impregnated foam backing. Both sides of the expansion joint are waterproof and fire-rated. Emshield WFR eliminates the need for fire blankets, mineral wools, liquid sealants, fire caulk, cover plates, or other fire stop materials. It can be used alone or under any other expansion joint cover, plate or filler where depth of substrate allows–with Emshield WFR one install does it all.
Non-invasive anchoring vastly simplifies installation and project sequencing. Emshield WFR fire-rated wall expansion joint is tested and certified by Underwriters Laboratories (UL), to the rigors of UL 2079 for wall and head-of-wall expansion joints as well as to California Department of Public Health CDPH/EHLB/Standard Method Version 1.2, 2017 for low-emitting materials.
