Intumescent Acoustic Ventilation Grille
The AVG/F intumescent acoustic 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. To accommodate the grille, the ventilation aperture must be at least 10mm larger than the height between the upper ad lower opposing slot limits. Also, the grille protrudes by 25mm on each side. Furthermore, see the order references tab for size options.
