Thermal & Acoustic Duct Insulation Services for AHU’s and HVAC systems Across the UK
Duct insulation is a vital part of any HVAC system, helping to maintain energy efficiency, indoor air quality, and acoustic comfort. Whether it’s for chilled air, heated air, or ventilation, effective insulation prevents thermal losses, condensation, and system inefficiency.
At Bremaco Ltd, we provide installation, repair, and replacement services for ductwork and pipework insulation in commercial, public sector, and industrial buildings throughout the UK.
How to Know When Your Insulation Is Not Working Properly
Watch out for these warning signs that your AHU duct insulation may be failing:
-
Visible damage, sagging, or missing insulation
-
Condensation or water staining near ductwork
-
Inconsistent temperatures in conditioned spaces
-
Unexplained increases in energy usage
-
Musty odours, indicating mould or damp
-
Noisy ductwork or airflow that was previously quiet
If you suspect an issue, our team can carry out a full inspection and thermal assessment to evaluate your insulation’s performance.

Yes, our technicians are trained to work in restricted spaces and elevated areas. We carry out safe, efficient installations with minimal disruption.
Do you offer weatherproof insulation for external ductwork?
Yes, we supply and install external-grade insulation with aluminium or PVC cladding to protect against UV, moisture, and temperature extremes.
Do you have to replace insulation that has become waterlogged.
Yes, we regard waterlogged insulation as failed that needs to be replaced.
