Emshield DFR3: Structural Expansion Joints

Emshield DFR3: Structural Expansion Joints

Emshield DFR3 is a  fire rated expansion joint, Emshield DFR3 is a watertight, traffic durable primary seal for repair, retrofit, and new installation in structural expansion joints and construction joints in horizontal-plane applications. Questions? Contact Us.

Emshield DFR3 is a 3-hour UL-certified fire barrier. (For 2-hour rating see Emshield DFR2)

Emshield DFR3 eliminates the need for fire blankets, mineral wools, liquid sealants, cover plates, 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.

Installed entirely from the deck surface, Emshield DFR3 vastly simplifies installation, project sequencing and coordination of trades by eliminating the need for access staging or obstruction by installation and presence of under-slab mechanical systems.

Emshield DFR3 is tested and certified by Underwriters Laboratories (UL) to the rigors of UL 2079 for deck and floor expansion joints.

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

Watertight — Emshield products are installed with the silicone bellows facing the weather to ensure watertightness. A field-applied sealant band of supplied silicone at the bellows to substrate interface seals substrate irregularities and completes the installation.

UL/ULC Fire-Rated — Tested in accordance with the cycling and fire endurance requirements of UL-2079, listed by UL, and manufactured under UL’s Follow Up Service ensuring that what is shipped is the same as what was tested.

Non-Invasive Anchoring — There are no hard metal-to-substrate connections with Emshield. 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.

Joint-Size Variation —through size-switching, material can be supplied to handle variations in joint size.

Sound Attenuation — Joints sealed with EMSEAL impregnated foam sealants offer exceptional acoustic dampening and feature STC/OITC sound transmission coefficients that can meet or exceed that of the assembly into which they are installed.
