Horn Group ApS - Ventilationsvinduet

Horn-Group Aps. has developed the ventilated window "Ventilationsvinduet", which adds freshly preheated air to buildings and contributes to a good indoor climate with a minimum of energy consumption. The ventilation window with Climawin valve technology (Pat.) is part of the NORFAC facade element solution and is available as a BIM object.


Horn-Group ApS offers the "Ventilation Window" in virtually all known wood / wood windows and wood / aluminum windows for all types of buildings in new buildings as well as renovation. The ventilation window has been tested and documented with funds from the EU and can be recognized in the building's energy framework for energy labeling. Horn-Group also offers total indoor climate solutions that include exhaust heat pumps and associated controls and documentation.


NORFAC is a Nordic research and development project involving 10 partners collaborating in the development of an innovative Nordic facade system.
The project is sponsored by Nordic Innovation and this website will contentiously  be updated
