Fire Rated Expansion Joint For Walls--EMSHIELD WFR2 from EMSEAL

EMSHIELD WFR2 is a watertight, fire-rated, dual-sided primary seal for both new and retrofit structural expansion joints in wall applications. As a single unit fire-rated expansion joint it eliminates the need for additional fire stops at the joint gap thereby eliminating the need for multiple separate products that perform the roles of sealing, bridging and fire-rating joints--with EMSHIELD WFR2, one install does it all.

For joints from 1 to 6-inches (25-150mm) where +25% and -25% (total 50%) of nominal material size joint movement is expected.

EMSHIELD WFR2 (Wall, Fire-Rated 2-Hours) is the second in a series of fire-rated expansion joints being released by EMSEAL. It can be joined with EMSHIELD DFR2, EMSEAL's horizontal deck fire-rated expansion joint, to create a continuous, fire-rated watertight expansion system in both planes as well as at factory-fabricated direction changes between the horizontal and vertical planes.
Because EMSHIELD WFR2 is coated on both sides it is an effective fire-barrier from either side in interior demising walls or partitions. Installed in exterior joints WFR2 can help to prevent wrap-around fires that exit the building through joint openings, wrap around the outside of the building and reenter the building through the joint at the next floor level.

EMSHIELD WFR2 provides a watertight, clean handling, UV stable, non-staining, low-temperature-flexible, high-temperature-stable, watertight, energy-efficient and fire-rated joint seal in a single installation process.
