Fire Grilles are mechanically attached to the supporting constructive element with the appropriate screws, plugs or fittings (these must have at least the same level of fire resistance as the structure onto which they are fixed).
If there are any gaps between the grille and the supporting element, these should be filled with Fire Grilles ntumescent mastic.
If the ventilation surface is bigger than the grilles dimensions, it is possible to assemble them at an angle, provided we keep the fire resistance and work consistency in the Fire Grilles separations.
For a greater ventilation arcare than the grille size.
Fire Grilles can be installed on the following structures: walls, doors, floors, ventilation systems, partitions, cable trays.
