Envirograf RS/WB Rainscreen Cavity Barriers are flexible and lightweight, preventing the spread of fire and smoke through cavity walls with intumescent strips that expand in fire to seal up gaps, offering fire protection for up to 132 minutes. By containing a fire and slowing its spread, more time can be allowed for evacuation, as well as less damage caused to surrounding rooms and buildings.
Rainscreen cavity barriers are used between brick or block walls, and rainscreen cladding, and are available to order with or without holes for ventilation and drainage. The holes allow airflow and moisture to pass through, and seal up in the event of fire. The barriers can be bent to shape without harming their fire-stopping and smoke-penetration integrity, and installed vertically and horizontally.
Made from 4mm galvanised mesh with intumescent-coated cloth, covered with reinforced craft paper that is with fireproof adhesive.
Depending on the width of the barrier, barriers are supplied with different fixings:
Up to 250mm wide barriers - These are supplied with 30mm up stand at the back, which include 3 fixing washers for fixing with screw or nails to concrete, brick, block, cement board, etc. 1m and 2m lengths available.
Over 250mm wide barriers - These are supplied with 30mm up stand at the back, which include 3 L-shaped fixing brackets. These brackets have holes ready for fixing with nails or screws. 1m and 2m lengths available.
Rainscreen barriers with brackets and CV strips can be ordered between 150mm and 350mm width.
