The Tecsel fire protection intumescent air grilles enable air to pass freely at room temperature through a structural part (walls, doors, etc.) while providing effective protection against flames, smoke and gases in the event of fire. When exposed to high temperature, they swell and form a layer of impact-resistant, non-flammable foam, which is an insulating layer preventing the penetration of flames, smoke and gases.

The Tecsel air grilles are designed for mechanical installation using screws, bolts, anchors or other fasteners, which should have the same fire resistance as the components on which they are installed. We recommend leaving a 2-3 mm gap around the air grille and fill it with a refractory glue, e.g. mcr Sil-MK. If the ventilation opening is larger, several air grilles can be installed, provided that the necessary fire resistance and distance between them are fulfilled.
They can be installed in:
For indoor use (avoid exposure to water, high humidity or temperatures in excess of 40°C).
Store in a cool and dry place.
