What the work involves
Undersized or leaky ductwork forces fans to work harder and makes systems noisy. We work to recognised sheet-metal ductwork specifications, seal joints, fit access panels for cleaning and insulate ducts that run through cold spaces or carry cold air. We install for our own ventilation systems and for other contractors, from short runs in a shop to full warehouse and office distribution.
Access panels
Fitted for future cleaning and inspection.
Spiral ductwork
Round galvanised ductwork for supply and extract runs.
Rectangular ductwork
For larger volumes or limited ceiling depth.
