Emseal DFR3 3-Hour, UL2079 fire and water-resistant expansion joint system for floors and decks

Sika Emseal Emshield® DFR3 is a watertight, fire-rated, traffic-durable primary seal for repair, retrofit, and new installations of structural expansion joints in horizontal-plane applications.

EMSHIELD DFR3 eliminates the need for additional fire blankets, mineral wools, liquid sealants, cover plates, or other fire stopping materials.

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

EMSHIELD DFR3 builds on EMSEAL's track record of over 30 years of innovation in sealing structural expansion joints with impregnated foam sealants and are part of a comprehensive line of breakthrough, multi-function, structural expansion joint materials offered by EMSEAL. Tested and certified by Underwriters Laboratories (UL), to the rigors of UL 2079 for deck and floor expansion joints.

ONLY FIRE-RATED EXPANSION JOINTS THAT HAVE BEEN UL 2079 TESTED AND CERTIFIED SHOULD BE USED IN A LIFE-SAFETY APPLICATION.

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