Acoustic Louvers 101

Louvers are used anywhere clean air is needed, but water and debris are not. In locations where sound levels are important, acoustic louvers are essential for minimizing infiltrating or escaping noise levels. With their sound attenuation technology and design, acoustic louvers are a must for office buildings, public buildings, condominiums, and other buildings where sound levels are critical to the effective design of the building.

What is a Louver?

A louver is a ventilation product designed to allow the passage of air while preventing the passage of unwanted elements like water, dirt, and debris. Louvers also serve aesthetic purposes as they can shield less attractive equipment from plain view and can be a key architectural element of a building.

The Design of a Louver

Louvers can be large and take up a great portion of a building's wall area. Other louvers used for mechanical ventilation are designed to fit in the intake or exhaust openings on a building or sometimes they are a part of the wall structure.

Typically rectangular or round in shape, the frame of the louvers mounts securely to the building and consists of blades that fill in the frame. The number of blades used, their depth, and the shape of the slat are all design parameters that affect the cost and performance and aesthetic appeal of the louvers.

Benefits of Acoustic Louvers

Acoustic louvers look very similar to standard louvers and come with blades that are already fixed in position. The blades are filled with an acoustical grade fibrous material that is used to attenuate sound. As sound travels through the louvers, the blades dissipate that sound, resulting in a quieter building. This extends to the exterior, ensuring quieter performance on the outside as well. Acoustic louvers are specially designed to ensure that they can deliver clean air while still attenuating sounds.

What is an Acoustic Louver?

Acoustic louvers are a special subtype of louver used where noise levels are important to an effective building design. While all louvers are used to limit the flow of water and debris, acoustic louvers have the additional duty of sound attenuation.

Acoustic Louver Design

The design of an acoustic louver is very similar to that of a standard fixed louver. The main difference may be an increased thickness of the blade. The thickness allows for space inside the blade to add sound attenuation material.

Types Of Acoustic Louver Blades

The blades of an acoustic louver are simply sloped louver blades available in either a box blade or airfoil shape. The blade design gives the acoustic louver exceptional performance while minimizing pressure drop and allowing for a great deal of sound attenuation.

AWV Acoustic Louvers

AWV offers 14 acoustically fabricated architectural louvers in various frame depths (6 to 12-inches), blade angles, and spacing. In addition, we fill each of the non-drainable acoustic blades with fire and water-resistant, sound-absorbing insulation.

The insulation allows for noise absorbance efficiency to reduce noise more than free-standing sound reduction enclosures. Our acoustic louvers have AMCA air and water certification, when applicable.
