Use the Envirograf AVG/F Acoustic & Fireproof Ventilation Grille on doors and partition walls, ventilating whilst absorbing sound and providing up to 60 minutes of fire protection.

The grille consists of 2 parts for each side of an opening, with the internals coated in micro-acoustic material, with intumescent strips on the two long sides of the risk side opening to provide fire resistance properties. These strips expand when attacked by fire, expanding to seal gaps to prevent the spread of smoke and fire.

To accommodate the grille the ventilation aperture must be at least 10mm larger than the height between upper and lower opposing slot limits (the slots should be vertically opposite each other not directly opposite each other when the grilles are fitted)

Material specifications:

  • Zintec steel plate grilles
  • Fire rated sponge
  • Intumescent strips protecting the risk side

Application:

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.
