Product Features

NCC acoustic louvres are multi-purpose, permitting air to flow, whilst shielding the environment from unwanted noise.

Our louvres are available in an array of standard modular sizes, meaning that a wide range of performance requirements can be met. By using our range of acoustic louvres, it overcomes architectural consistency issues, especially where space is limited. 

 

1.Rugged all-steel galvanised construction. Stainless steel, aluminium
and other materials are also available
2.Inert, vermin-proof, weather-rated non combustible acoustic fill
3.Shaped splitter blade for maximum noise reduction with minimum pressure drop
4.Perforated splitter underside for maximum sound absorption
5.Weather stop inhibits rain/snow entry
6.300mm deep single banked systems and 600mm deep for the double banked system
7.Available in a variety of durable, attractive finishes,such as  vinyl coated steel, polyester powder paint, anodised aluminium,  galvanised and stainless steel
8.Modular sizes enable assembly of rectilinear louvre 'walls' of almost any size
9.Louvre blade orientation blocks horizontal line of site, enhancing both aesthetics and acoustic performance
10.Bird guards are available in galvanised or stainless steel, insect screens can also be supplied
