If the home lacks balanced ventilation: both air extraction and air intake are mechanical with balanced ventilation, usually through supply and exhaust valves mounted in a ceiling or wall. Because this form of ventilation and extraction is not present and the extraction is accomplished differently, it's important that fresh air can enter the home through grilles. Such grilles are usually located above the glazing or above a window frame in all living areas, ensuring a healthy indoor climate.
The ventilation grilles above the windows/frames must be properly maintained. Insufficient maintenance prevents them from functioning optimally. If the grilles are dirty, they should be cleaned, which can be done yourself. It's not easy to calculate whether the grilles have sufficient capacity. Moderate to insufficient maintenance can cause components to not function as intended or to function less efficiently. We recommend carrying out any overdue maintenance in accordance with the supplier's instructions. Maintenance instructions for maintaining the ventilation grilles can be obtained from the supplier or downloaded online.
If ventilation grilles above the windows/frames are no longer fully or partially functioning, the ventilation in your home is disrupted and unhealthy. In such cases, ventilation grilles will need to be replaced. The downside of this is often that the glazing has to be removed and replaced, which can damage the paintwork, and so on. Consult a qualified glass retailer; they may have some interesting options for you.
