Emseal Emshield WFR2

Emshield WFR2 (Wall Fire Rated 2-Hours) 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.

Key Features
  • Watertight – EMSHIELD WFR2 is installed with tensionless bellows, which when installed with an optional silicone bead on the weather face, maintain a watertight seal.
  • Fire-Rated – The fire-retardant-impregnated foam, when properly installed, ensures a 2-hour fire protection in accordance with UL-2079 and has also been BRANZ appraised for 2 hours of fire resistance. 
  • Sound Attenuation – EMSHIELD WFR2 minimizes sound transfer which often occurs at the expansion gap. The tested results for 1 1/2” WFR2 in an STC 68 / OITC 51 wall are an STC value of 64 and an OITC value of 52.
  • Non-Invasive Anchoring – There are no hard metal-to-substrate connections with EMSHIELD WFR2. 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.
  • Testing and Standards - EMSHIELD WFR2 has been tested and certified under AS 1530.4-2005, UL 2079 and has been tested and appraised by BRANZ (FR 4002).

Limitations on Use

Substrates must be solid, sound, parallel and plumb.

NB: Overall fire-rating of a wall assembly is dependent on the fire-rated characteristics of the supporting and adjacent wall design by others.

Statement of Building Code Compliance

According to BRANZ Fire Assessment Report 4002, Emshield WFR2 Fire-Rated Expansion Joints achieve an integrity and insulation of at least 120 minutes if tested in accordance with AS 1530.4-2005.

Other Performance Attributes

As a single unit, fire-rated expansion joint, EMSHIELD 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.

This can be used alone or under any other expansion joint cover, plate or filler where depth of substrate allows.

NB: Also avaliable in 3 hour fire resistance.
