Indoor climate and energy optimisation are in focus in new houses as well as old houses, and good and efficient ventilation is of great importance.

When a ventilation system needs to be replaced or starts to leak, a renovation of the existing channels will often be a quicker, more flexible and profitable solution than replacing them with new ones. Aarsleff specialises in the CIPP Lining method – a method suitable for renovation of ventilation channels and approved for supply air.

Uses the existing channel
A CIPP Lining will make the channels tight and serviceable again. The process is carried out by installing a CIPP Lining inside the existing channels – with only a minimum reduction of the cross section. Our solution is used in natural vents and/or in cancelled chimneys. This way, we avoid demolition of walls, installations, floors etc.

Minimum nuisance – and costs
A CIPP Lining has a long life, but a short installation time. The process is significantly faster than traditional replacement. And we do not have to enter the building and make serious interventions in the existing installations. As a result, nuisance such as noise, dust and disturbances are reduced to a minimum.

A renovation with Aarsleff CIPP Lining is also a more economical solution than a new installation: The installation time is shorter, and you will save the subsequent reinstatement costs for e.g. carpentry, masonry and painting.
