Emseal DFR CE fire-rated CE expansion joint CE-certified

An EN-1366-4 tested, fire-rated movement joint, Sika Emseal Emshield® DFR CE is a silicone-faced movement joint for European and other markets requiring CE marking. Tested by CSTB France and certified by European Technical Assessment (ETA), Emshield DFR CE provides up to 4-hours of fire resistance, and is a water, air, and smoke seal with 100% movement capability. Other features include thermal insulation, UV stability, and trafficability. In contrast to fire barrier blankets Emshield DFR CE is installed entirely from above the floor slab and performs without the need for invasive metal anchors or complex field fabricated assemblies. Emshield DFR CE provides a cost effective, long-term watertight seal.

Emshield DFR CE combines a factory-applied, low modulus silicone with an open cell polyurethane foam infused with a water-based, fire-retardant, acrylic dispersion. The traffic-grade silicone facing is factory adhered to the infused foam on two sides at a width greater than the maximum anticipated joint extension, and is then cured. When compressed, the silicone facing forms a bellows profile capable of accommodating +/-50% (total 100%) movement from the product’s nominal size. The bellows fold, and unfold during movement virtually free of tensile stresses.

Emshield DFR CE is supplied precompressed to slightly less than its nominal size for ease of installation. To install sticks, clean the substrate faces, apply supplied epoxy adhesive to the substrates. After removing packing materials insert the Emshield DFR CE into the joint. After the Emshield DFR CE has expanded to fill the joint space and is adhered to the substrates, a field-applied silicone corner bead ensures a watertight seal at the substrate interface.

Features

Watertight – Emshield DFR CE is manufactured with tensionless silicone bellows, which when installed with an optional silicone bead on the weather face, maintains a watertight seal in accordance with NF 12154 testing.

Fire Resistance – The fire-retardant-impregnated foam, when properly installed, ensures a 1, 2, 3 or 4-hour fire protection in accordance with EN 1366-4 testing.

Sound Attenuation – Emshield DFR CE minimizes sound transfer which often occurs at the expansion gap.

The Rs.w (C ; Ctr) : is greater than or equal to 54 (-1 ; -3) in accordance with NF EN 10140-2 (2013) and NF EN 12999-1 (2014)

Non-Invasive Anchoring – There are no hard metal-to-substrate connections with Emshield DFR CE. The system is fastened 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.

Uses

Emshield DFR CE is used in floors and decks. In deck and roadway usage it can be manufactured with a traffic-grade silicone surface and can be used alone or under any other movement joint cover, plate or filler where depth of substrate allows.

Sizes

For joints from 12mm (1/2-inch) up to 100mm (4-inch)

Movement

+50% and -50% (total 100%) of nominal material size joint movement in accordance with ASTM E1399, UL 2079 and EN 1366-4.

Color

The silicone faces of Emshield DFR CE can be manufactured in a variety of different colors to blend with their adjacent surfaces. They are available in a complete line of Dow 790, Pecora 890 and Dow 748 industry standard colors.
