Commercial ventilation, Dyfed
Ductwork installation in Dyfed
Spiral and rectangular galvanised ductwork, hung, insulated and sealed, across Dyfed.
- From £45 + VAT per metre
- Free survey
Ductwork carries air between the fan or unit and the rooms it serves, and how it is sized, hung and sealed decides how well the whole system performs. We supply and install spiral and rectangular galvanised ductwork, fittings, dampers, insulation and access panels.
We carry out ductwork installation across Dyfed, including Milford Haven, Llanelli, Ammanford, Aberystwyth and Carmarthen. Prices use Wales rates. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it
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.
