Summary
Aluminium wall louvre with sound-absorbing, non-flammable mineral wool.
Aluminium wall louvre with sound-absorbing, non-flammable mineral wool.
Application
Louvre for wall ventilation, suitable where reduced noise transmittance is required.
Louvre for wall ventilation, suitable where reduced noise transmittance is required.
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).
