The AVG/F fireproof ventilation grille consists of two parts, one for each side of the opening. The internal cavity of both sections is filled with micro-acoustic material, with intumescent strips on the two long sides of the risk side opening to provide fire resistance properties.


– Offers up to 60 minutes protection, as well as sound absorption

– Ideal for use on partition walls and doors to provide ventilation between rooms while preventing sound transfer

Application Instructions

Ensure ventilation aperture is at least 10mm larger than the height between the upper and lower opposing slot limits. Screw grille plates in place on either side of the opening ensuring the ventilation slot is at the top on one side and the bottom on the other so that they are vertically opposite (not directly opposite each other).

Note: the grille plates will protrude by 25mm on each side.
