Fire Resistant Floor & Wall Movement Joints - Emshield DFR / WFR CE

Emshield DFR / WFR CE are CE-marked, ETA-certified, up to 4-hrs fire-rated, double-sided silicone-faced movement joints. They provide a watertight seal with 100% joint movement capability (+/- 50%), good sound attenuation, high and thermal insulation and long-term UV stability, for us within vertical (WFR) or horizontal (DFR) substrates, and with colour coordination possibilities.

The system includes water-repellant silicone sealing surfaces fully adhered to a fire-retardant impregnated foam backing. The symmetrical design allows either side to face out from an exterior or interior wall or floor/deck and to maintain a 1, 2, 3 or 4 hour fire resistance as required for the joints. The field-applied silicone bands ensure the face is completely watertight.

Each system profile is installed by fully bonding directly into the structural epoxy adhesive, which is field-applied to the prepared joint arrisses, with no mechanical fixings being required. Connections between each preformed section / piece are made using the field-applied intumescent sealant on the adjoining faces of the foam cross section, plus the field-applied silicone sealant continues across the join at the bellows’ edges.

Emshield DFR CE and WFR CE have been tested and certified in accordance with EN 1366-4, as well as EN 12154 and EN 12155 with no leakage with up to 1200 Pa of pressure. It also meets the requirements of ASTM E1966, ASTM E119 and ASTM E1399.

Features and benefits:

• Watertight.
• Fire resistant up to 4 hours.
• Good sound attenuation.
• Non-invasive anchoring (fully bonded).
• Nominal joint sizes (Standard): 12–100 mm.
• Factory-fabricated transitions (i.e. corners, upstands and cross sections etc.).
• Joint movement capability up to 100% (+50% / -50% (100% total) of nominal material size (width) e.g. a nominal joint width of 100 mm sealed with Emshield DFR/WFR-CE, will safely accommodate up to 100mm movement from 50mm to 150mm, including frequent, cyclic movement. It can also accommodate movement in more than one plane.
• Colour options
