Therm-A-Grille consists of two sheets of Steel mesh that have been coated with a graphite based intumescent material. The coating thickness has been optimized to ensure rapid activation whilst maintaining a high free area and good air flow rate.
The sheets are folded to form a box section which gives the assembly high strength and rigidity, provides a flange for fixing and carries an intumescent edge seal. There is very little heat transfer between the two grille plates to ensure good insulation.
Therm-A-Grilles are 38mm thick for fitting to any 30 minute or 60-minute fire door. Please note that all sizes are listed as width x height.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Firewise Supplies is consulted before specifying.
