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.
Rectangular ductwork
For larger volumes or limited ceiling depth.
Insulation and fire dampers
Thermal insulation and dampers where ducts pass through compartments, as designed.
Access panels
Fitted for future cleaning and inspection.
