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.
Jet cowls offer an advantage over standard round cowls in that expelled air is directed vertically rather than laterally - as is common with most roof terminations. This decreases the possibility that exhaust fumes present a nuisance to neighbouring buildings. Using a jet cowl often means a vertical duct can be shorter than it would otherwise need to be with a standard cowl.
Rainwater is caught in a dish within the cowl and is fed out through a drainage tube.
Jet cowls are designed to connect directly to spiral duct tube
