Please note that linear bar grilles manufactured to order may take longer than advertised due to - what we hope is - a temporary material shortage. Lead time is currently around 2-3 weeks. We apologise for any inconvenience this may cause. All other grilles and louvres are unaffected.

Aluminium weather louvres

Satin-anodised aluminium weather louvres. Light gauge bird mesh to rear. Approx. 40mm blade pitch. These louvres are generally held in stock.

Please note that sizes refer to duct size i.e. the size of the duct or aperture they are designed to fit. For overall size (including flange) add 45mm.

Note that louvres have depth and require an aperture to fit into. The aperture required is the nominal size of the louvre e.g a 200x200mm louvre will require a 200x200mm aperture.

For information on sizing weather louvres correctly please see:
