Emseal Emshield® WFR3 Expansion Joint

A fire rated wall expansion joint, Emshield WFR3 (Wall, Fire-Rated 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 WFR3 is a 3-hour UL-certified fire barrier and preformed alternate to fire caulk and fire stop materials. (For 1-hour fire rating see Emshield WFR1 or for 2-hour fire rating see Emshield WFR2)

Emshield WFR3 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 WFR3 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 WFR3 one install does it all.

WFR3 is available in customized sizes to fit almost any vertical fire-rated joint. Please contact us for a project-specific quote at one of the numbers below and make sure to check out the checklist.
