- 87% heat recovery
ProjectsThe iV14-Zero Prefab in action
The iV-Zero Prefab is the ideal ventilation solution for serial refurbishment projects in residential construction, where most of the refurbishment is carried out on the outside of the building. The innovative Prefab design enables simple integration into the façade – with an internal air outlet in the window reveal. This clever corner solution ensures maximum design freedom and an unobtrusive appearance. As with the iV14-Zero, the iV-Zero Prefab also impresses with patented sound insulation with Inventin®, high
heat recovery, the powerful Xenion® fan, a lockable inner cover and a driving rain-proof weather protection hood – customizable for each project in many RAL colors.the future of building with serial refurbishment
