A fire rated expansion joint, Emshield DFR2 is a watertight, traffic durable primary seal for repair, retrofit, and new installation in structural expansion joints and construction joints in horizontal-plane applications. Emshield DFR2 eliminates the need for fire blankets, mineral wools, liquid sealants 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.
