What ductwork installation 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.
Insulation and fire dampers
Thermal insulation and dampers where ducts pass through compartments, as designed.
Access panels
Fitted for future cleaning and inspection.
Spiral ductwork
Round galvanised ductwork for supply and extract runs.

Questions about ductwork installation in Mid Glamorgan
Which rules apply to ventilation in Mid Glamorgan?
In Wales, the Welsh Government's own Approved Document F (2022 edition) applies to ventilation in homes, with a new edition taking effect on 4 March 2027. Rented homes must be fit for human habitation under the Renting Homes (Wales) Act 2016, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
Spiral or rectangular duct?
Spiral duct is quicker to install and leaks less; rectangular duct fits shallow ceiling voids and larger airflows.
Do ducts need insulation?
Ducts carrying cold or warm air through unheated spaces usually need insulation to prevent heat loss and condensation.
