Acoustical Louvers

METLANE acoustical louvers are adaptable to different types and dimensions of conventional, commercial and industrial buildings, as well as to modular structures.

Their primary application is to provide noise reduction to air intake and air exhaust applications into walls or acoustical enclosures. They can also form complete acoustical walls or enclosures. Louvers can be stacked in modules, framed or self-supported as necessary. Their optimized aerodynamic shape minimizes insertion loss while maximizing noise reduction.

Acoustical louvers allow the creation of an aperture in a building for air exchange without compromising its aesthetic appearance. They are generally painted or anodized for aesthetic purposes and durability. They provide an exceptional architectural finish.

CONSTRUCTION - Louvers are generally made of galvanized or satin coated sheet steel but are also available in stainless steel or aluminum. Their blades are soundproofed with Rockwool, covered or wrapped with a protective film when required. Louvers can be shipped in sections, with or without a mounting frame according to specifications. Dimensions, composition and design vary from project to project.

FINISH - Our Louvers come in different finishes. They can be made of anodized aluminum for a long-lasting finish or made of satin coated steel or aluminum with a polyurethane paint or polyester powder paint in a variety of colors and gloss or matt finish. Our paints provide an impeccable and long-lasting finish, large temperature range and UV ray resistant.

SELECTION - Our acoustical louver catalogue contains all relevant technical information (noise reduction, insertion loss and others), along with a selection method and installation guidelines. Louvers will soon be available for selection from METLANE Selection^TM software.

PERFORMANCE - Testing has been performed on different types of louvers by the independent NVLAP accredited Intertek laboratory according to ASTM E90 and AMCA 500. These tests helped to validate the design of the louvers and optimize their performance.
