ACOUSTIC LOUVER
Acoustic Louvers offer excellent noise reduction for car park, mechanical rooms, cooling towers, factories, and workshops, or any other application where ventilation and noise control are both required at the same time.
What is Acoustic Louver System
Allows air entry
​
Minimizes noise outbreak
Performance determined by depth, blade design, opening size, etc
HORIZONTAL ACOUSTIC SINGLE-BANK LOUVRE
HORIZONTAL ACOUSTIC DOUBLE-BANK LOUVRE
HORIZONTAL ACOUSTIC DOUBLE-BANK LOUVRE
TWF Acoustic Louvers are certified for their performance by the Riverbank Acoustical Laboratories in Geneva, Illinois.

Key Features
PREVENT NOISE BREAKOUT
Acoustic Louvers prevent noise breakout from an air inlet or outlet of a plant room, building, or enclosure while allowing ventilation air transfer.​
PERFORMANCE-BASED
They have varying acoustic performance depending on the type of aerodynamically designed blades used and the depth of the Acoustic Louver demanded by the design.​
NOISE REDUCTION
For a 10dBa reduction in sound, the perceived noise reduction to human ears is about 50%.​
STC RATING
The Sound Transmission Class (or STC) is an integer rating of how well a building partition attenuates airborne sound. The STC rating figure roughly reflects the decibel reduction in noise that a partition can provide.​
