Therm-A-Grille

Therm-A-Grille is suitable for vertical apertures in fire resisting doors and compartment walls.

It is held in position by means of 50mm No.8 size steel screws (not supplied) through the unit’s frame at 150mm centres.

Fitted centrally within the aperture.

Where the wall includes a cavity e.g, plasterboard/timber stud partitions then the aperture must be lined with fire resisting material e.g. a steel sleeve to the full depth of the aperture.

Apertures in fire resisting door leaves should only be formed by suitably qualified door converters to ensure that the fire integrity of the door is not compromised.

Facia or louvre plates (not supplied as standard) may be fitted to either side of the aperture.
