Fan, duct and grille sizes are designed for air flow, noise and energy use.

Ductwork and fans are installed and connected to controls. We keep work areas in Dumfries and Galloway screened and tidy at the end of each day.
Balance
Air flows are measured and balanced to the design.
Things to check in Dumfries and Galloway
Noise
Fans and grilles are selected and attenuated to keep noise down.
Access and parking
Town-centre jobs in Dumfries and Galloway often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
