x-well® decentralised domestic ventilation

Installed retrospectively or planned right from the start. Decentralised residential ventilation systems can be installed specifically in the individual rooms. This can be done with little effort and is therefore not only possible for new-builds, but also retrospectively for renovations. Uncomplicated, cost-effective, maintenance-friendly. Good thermal comfort with the lowest possible energy costs – with x-well decentralised residential ventilation you have found the perfect solution for new or old buildings. The small ventilation systems are installed separately for each room. In the case of renovations, this can be done quickly and without great effort by drilling a core hole through the outer wall. In new buildings, there are special installation bricks for this purpose or, as another elegant alternative, integration into the window reveal. In any case, this ensures that there is fresh air in every room. With pleasant appearance inside, visible from the outside only as an inconspicuous ventilation grille.

The outer panels blend perfectly into the look of any house.
