Service
Ductwork Insulation
Thermal and acoustic insulation for supply, extract and chilled air ductwork across commercial and industrial buildings.
Quick answer
What is ductwork insulation?
Ductwork insulation is the wrapping or internal lining of HVAC ductwork to reduce heat loss or gain, control condensation, and reduce noise transmission. We install thermal and acoustic systems on supply, extract and chilled air ducts to project specification.
What's included
- Thermal ductwork insulation (foil-faced mineral wool)
- Acoustic ductwork insulation
- Internal duct lining where specified
- External ductwork insulation and finishes
- Supply and extract air systems
- Chilled air ductwork with vapour control
- Repair and replacement of failed insulation
Typical applications
- · Commercial HVAC systems
- · Hospital ventilation
- · School and university air handling
- · Industrial extract systems
- · Data centre cooling distribution
- · Mixed-use developments
Why this matters
Ductwork insulation maintains delivered air temperatures, prevents external condensation on chilled air ducts and reduces breakout noise. On rooftop and external runs, weatherproofing protects the insulation system from moisture ingress.
Materials & systems
Common materials include Isover Ductwrap and Rockwool slabs, alongside acoustic linings and project-approved alternatives. Selection is driven by thermal/acoustic duty, location and specification.
Technical & commercial notes
We work from M&E layouts and duct schedules, coordinating with the ductwork installer to keep the programme moving.
Frequently asked questions
- What is ductwork insulation?
- Insulation applied to HVAC ductwork to control heat loss/gain, prevent condensation and reduce noise. It can be applied externally as a wrap or internally as a lining.
- Do you insulate external rooftop ducts?
- Yes. External ducts are insulated and then finished with a weatherproof system — typically aluminium cladding or PIB — to protect against moisture and physical damage.
