The challenge
Traditional replacement is expensive, slow and CO₂-heavy.
When ventilation ducts need renovation, demolition and new construction are typically chosen by default. This means extensive intervention in the building, large amounts of waste, prolonged construction time and a significant climate footprint – without it always being technically necessary.
More
demolition
Interventions in structures, ceilings and shafts.
More
waste
Tons of duct material end up as construction waste.
More
relocation
Residents and users must be moved during the work.
More
downtime
Systems and rooms are taken out of service for long periods.
Higher
CO₂
Production and transport of new ducts burden the climate.
Our solution
Coating makes it possible to reuse what is already there.
We renovate existing ventilation ducts from the inside with a documented coating process. The system is back in operation with an extended lifetime – without demolition, without new ducts and without major intervention in the building.
- Step 1
Inspection
Ducts are mapped and assessed with camera and measurements to determine reuse potential.
- Step 2
Cleaning
Interior cleaning removes dust, grease and deposits – the duct is prepared for coating.
- Step 3
Coating
A specially developed coating is applied internally and seals the duct, including against moisture, corrosion and chemicals.
- Step 4
Documentation
The finished quality is documented with tests, photos and a report.
Benefits
A solution that meets the needs of owner, user and building.
Lower CO₂
Significantly lower climate footprint than replacement. Reusing existing materials feeds directly into the building's green accounts.
Faster projects
Fewer trades, fewer interventions, shorter construction time. The system is typically back in operation in a fraction of the time.
Lower total cost
Reduced costs for demolition, new ducts, relocation and consequential work on the building.
Documented quality
Tests for fire, pressure loss, EPD and chemical resistance document the quality – from consultant to operations.
