Description
Acoustic Ventilation Grille
The AVG acoustic ventilation grille consists of two parts, one for each side of the opening.
- Micro-acoustic material sits within the internal cavity, thus providing effective sound reduction.
- Easy to mount onto a dorr or wall with screws.
- Made from extruded aluminium profiles and consists of two sections with a 35mm wide edge. Both sections have u-shaped profiles containing micro-acoustic material.
- Owing to the fixed profile system, the profile/gap interval must be a multiple of 85mm up to a maximum of 935mm (from 1 to 11 vanes).
- The area of ventilation available is about 29% of the total grille plate area.
The AVG acoustic ventilation grille is made to order, therefore available in a range of sizes and finishes, prices on application.
Furthermore, acoustic properties tested to ISO140-3 (1995).
