    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.

    Non-invasive anchoring vastly simplifies installation and project sequencing. Emshield WFR3 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.

    Where UL tested listings do not meet your specific project conditions ask EMSEAL for an engineered judgement.

    Watertight — Emshield products are installed with the silicone bellows facing the weather to ensure watertightness. A field-applied sealant band of supplied silicone at the bellows to substrate interface seals substrate irregularities and completes the installation.

    UL/ULC Fire-Rated — Tested in accordance with the cycling and fire endurance requirements of UL-2079, listed by UL, and manufactured under UL’s Follow Up Service ensuring that what is shipped is the same as what was tested.

    Non-Invasive Anchoring — There are no hard metal-to-substrate connections with Emshield. This includes embedded pins, anchors, screws, bolts or tracks, trays or rails, flanges or coverplates. The system is locked to the joint faces by means of the 1) backpressure of the foam; 2) the epoxy adhesive, and 3) the injected sealant bands at the joint face.

    Joint-Size Variation —through size-switching, material can be supplied to handle variations in joint size.

    Sound Attenuation — Joints sealed with EMSEAL impregnated foam sealants offer exceptional acoustic dampening and feature STC/OITC sound transmission coefficients that can meet or exceed that of the assembly into which they are installed.
