Emseal DFR2

DFR2 2hourFireRatedExpansionJointDeck 250pix

Emseal EMSHIELD DFR2 is a watertight, fire-rated, traffic-durable primary seal for repair, retrofit, and new installations of structural expansion joints in horizontal-plane applications.
EMSHIELD DFR2 eliminates the need for additional fire blankets, mineral wools, liquid sealants, cover plates, or other fire stopping materials.

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

UL-certified 2-hour fire-rated watertight expansion joint for use in a deck or floor with a 2-hour (or lower) fire rating. Used in deck-to-deck applications or deck-to-wall applications.


  • For Floors and Decks
  • Interior and open air

Standard Sizes: 12 - 100mm
Note: Sizes under 40mm are manufactured with a single bellows. Larger sizes incorporate multiple bellows. (Above 100mm see SJS SYSTEM)
Depth of Seal for all sizes: 100mm (4")
Movement Capability: Up to 100% total (+/-50% of nominal supplied size)


  • Emseal standard colour is grey (contact Allco to discuss other options)
  • Standard underside silicone colour is also grey. Alternate colour coating on bottom side is available as an option (contact Allco to discuss other options)
  • appraised
  • Watertight — EMSHIELD DFR2 is installed with the tensionless traffic-grade, fuel-resistant bellows facing the traffic ensuring that watertightness is achieved.
  • Fire-Rated — The fire-retardant-impregnated foam ensures 2-hour (DFR2) fire protection in accordance with UL-2079 and BRANZ Appraisal (FAR 4002).
  • Non-Invasive Anchoring — There are no hard metal-to-substrate connections with EMSHIELD DFR2. 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.
  • Versatility — The standard EMSHIELD DFR2 top surface and underside colour is grey. At the designer's option, other colours are optional and a different silicone colour coating can be applied to the underside.
  • Joint-Size Variation —Uniform bellows appearance, and the ability to handle variations in joint size through size-switching.
  • Sound Attenuation - Floors sealed with EMSEAL impregnated foam sealants offer exceptional acoustic dampening and feature sound transmission coefficients virtually equal to that of the solid slab.

Performance Limitations: DFR2 is capable of +/-50% movement for nominal material up to 100mm (4”), for vehicular and pedestrian trafficked conditions. For applications in larger joints (76mm and above) where full extension movement and high point load, small-diameter-wheel conditions (shopping cart, luggage carts, etc.), designer should consider use of a cover plate over the DFR2 or instead specify the SJS-FR system.
