About Memory Spring Set Intumescent Fire and Smoke Grilles

Intumescent grille with a memory spring for walls, ceilings, fire doors and ventilation inlets.

Regulations often require fire and smoke protection grilles for openings in fire walls. The Envirograf TJ Grille fulfils this requirement offering full fire and smoke protection. This type closes when the fire gets near the grille. At 50 C to 65 C the grille will close, but the spring returns to the open position once the fire is over.
