With window ventilation, you bring fresh air into your home in a natural way via the dry zones such as the living room and bedroom. This advantage alone makes the investment worthwhile. Simply because using this method - in combination with a solid system for discharging polluted indoor air – you are guaranteed to benefit from healthy indoor air at all times. In addition, these ventilation grilles are installed so that they do not visually interfere with the overall appearance of your facade, but do offer acoustic damping and help to avoid cross ventilation (or bilateral ventilation).
