aluminium weather louvres

External aluminium weather louvres with bird mesh. Manufactured from extruded aluminium alloy with a slimline blade. Excellent resistance to rain whilst maintaining a 50% free area. Approx. depth 45mm.

While we do keep a limited stock of square louvres, due to the vast array of possible sizes, louvres are generally made to order, therefore please allow 1-5 working days.

Please note that the sizes stated refer to the duct size, or neck size of the louvre. It does not include the flange. The overall size i.e. including the flange, is the duct size + 48mm. e.g. a 400x400 louvre will fit 400x400 duct and will have an overall size of 448x448mm.

Plenum boxes to enable connections to circular ducts can be found here
