Intumescent Grille 400x400

FG40 FIRE STOP INTUMESCENT GRILLE/FIRE DAMPER (Multi-purpose with Architectural Finish).

Firepro FG40 Fire Grills are designed to protect apertures in fire resistant structures. Under normal conditions they allow free flowing ventilation, however in the event of a fire they will rapidly seal off the opening to provide complete fire integrity. The grills are attractive, simple to install and very economical. Major applications include air ventilation through fire-rated walls and floors and in metal ducting penetrating floors and walls.

CONSTRUCTION The units are constructed from rigid PVC extrusions of hollow cross section which is filled with intumescent material. They are robust, easily cleaned and have no moving parts to require maintenance.

OPERATION Under fire conditions the intumescent core expands and the casing becomes soft and pliable, allowing rapid unrestrained expansion of the core. The intumescent core has a low response temperature and rapid response time, quickly expanding to many times its original thickness, forming a firm non-combustible fire seal.
