 The system incorporates an intumescent fire block grille, which fits within a door leaf aperture sandwiched between a specially designed two-part steel louvre set. If a fire occurs, the intumescent expands, filling the door void and thus preventing flame spread.
Suitable for both timber and steel fire doors, the system comes in mild steel or stainless steel options in either nine standard sizes or any size made-to-order.
