For what wall thickness are Ventoxx HRVs suitable?

Ventoxx products are suitable for most common apartment buildings built of bricks or panel blocks, as well as for cottages built according to individual projects. The length of the duct located in the wall thickness can vary freely.

Its minimum design length is 320 mm, and the maximum one depends on the customer's needs. It can easily be increased with the use of stacking rings.
For the buildings with especially thin walls from 150 mm, our product range includes the Ventoxx Slim Line HRV model. Its design uses an expansion box that allows you to compensate for the lack of thickness of the partition wall and fully insulate the HRV.
