Description
The AVG/F fireproof ventilation grille consists of two parts, one for each side of the opening. Micro-acoustic material sits within the internal cavity on both sides. Designed with intumescent strips on the two long sides of risk side opening, thus providing high performing fire resistant properties.
Advantages
– 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.
