Description
A sound attenuating built-in wall grille, crafted from extruded aluminium profiles. The louvre blades are locked into place fast and easily on plastic blade holders, and are fitted with sound-attenuating, inflammable mineral wool on the inside.
Features and benefits:
- Sound-attenuating, inflammable mineral wool on the inside.
- Available as anodized or powder coated RAL finish.
- Manufactured from extruded aluminium profiles.
- High damping value.
- Low resistance factor (and consequently a better flow rate).
