Grilles, Diffusers & Cowls

The extraction grilles here are sorted into internal and external although some are suitable for both. Diffusers supply air and the grilles normally extract. Most have a connection on the back for ducting but some require a plenum box. The roof cowls section also contains flashings etc for fitting.
