Introduction
The door grille rated ventilators are suitable for 1 hour rated doors and partitions. The units, which satisfy BS 476 Part 22, incorporate intumescent elements which expand and carbonise when exposed to temperatures in excess of 150°C, thereby sealing off the ventilation opening.
The ventilators may be beaded directly into the door/partition opening or covered by optional steel grilles to suit aesthetic requirements.
The door grille are constructed from aluminium extrusions. The extrusions are retained in a horizontal louvre pattern by reinforced vertical members and an enclosing frame system.
