There is a strong relationship between health and the indoor climate. Asthma and certain allergies are strongly related to air quality in the home or workplace. In new, well insulated and airtight houses there is little or no natural ventilation. For security reasons and to prevent draught and heat loss we often do not open windows anymore. This can lead to high humidity and a build-up of harmful gases such as carbon dioxide, carbon monoxide and radon. Radon from outside is largely controlled by a radon barrier in newer houses but certain common building materials also emit radon and other noxious substances like formaldehyde. Increased humidity can lead to mould, which is fungus and can affect health. To eliminate these harmful effects, it is essential to bring in fresh air and remove the stale, polluted air.

Our balanced ventilation system generates a steady stream of fresh filtered air and recovers up to 95% of the heat of the extracted air. It guarantees a pleasant and hygienic indoor climate with no draughts.
