G.A.S Combi Ducting 5m & 10m
£11.95
Combi ducting is much tougher and easier to work with than standard aluminium ducting as it has a black plastic insulation style tape around the outside which makes it stronger and unable to tear.
It also protects against unwanted smells leaking out your room as the there are no tiny holes running through it as it has on the aluminium duct.
