Description

A range of fire and smoke resistant vent grilles for UPVC or metal door and window frames, supplied as HMG and SVG types. They improve ventilation while maintaining the fire performance of the frame.

Whether the grille is open or closed, the multi-directional intumescent expands and seals the opening to contain a fire before it spreads. Typical locations are bathrooms, kitchens and corridors.
