Slotgrilles are manufactured from horizontal slats of high performance intumescent spaced 16mm apart. 38mm thick units provide up to 60 minutes fire resistance.

Circular Slotgrilles are available in standard sizes of 100mm, 125mm, 150mm and 200mm diameter.

Slotgrille air transfer grilles can provide up to 60 minutes integrity and insulation in accordance with BS 476 Part 22 1987, but still allow 60% free air flow in normal use. Slotgrille units can be fixed into fire resisting doors or timber stud partitions using a hardwood or steel flange. Alternatively wood screws can be used through the perimeter of the units.

Gaps around the Slotgrille unit greater than 3mm should be fire sealed using an intumescent sealant.

Ventilation Ducts:-

Slotgrille dampers must be secured within the ducting using 4 self tapping screws. On circular Slotgrille the screws should pass through the aluminium rings on the outer part of theSlotgrille. Clearance gaps should be sealed using an intumescent sealant.

Slotgrilles can be ordered by contacting our sales department. When ordering please state, fire resistance required, width, height and colour.

Ventilation and air conditioning ducts that penetrate fire separating elements need to have their integrity maintained. This also applies to fire resisting doors that require the passage of free air through them, such as doors to boiler rooms.

Since there are no moving parts to go wrong, Slotgrilles are easily maintained. Units should be cleaned using a damp cloth. Grease can be removed by using neat liquid detergent or methylated spirit. Strong degreasing agents should not be used nor should the units be immersed or saturated with water.
