Grilles
Supply, return and transfer grilles for walls, ceilings, doors and ducts
Grilles cover the openings where air enters or leaves a space. Adjustable blades direct supply air; fixed or egg-crate cores maximise the free area for return and extract air.
We supply single- and double-deflection grilles, linear, egg-crate, perforated and door grilles, together with plenum boxes and access doors for complete installations.
