Family homes

Housing demands are on the rise. We like to enjoy our home in comfort with easy maintenance and low operating costs. However, the most important thing is to live with our children and family in healthy environment. Not a long time ago, we started using finer materials to build our homes. The trend of thermal insulation with plastic airtight windows achieved the target to isolate buildings completely. Unfortunately, this brought severe adverse effects in the form of unnatural internal environment with unhealthy levels of humidity, CO2 and other pollutants. The only solution to this problem is to open the windows. Naturally, this means heat loss and influx of pollution and noise. Ventilation system with heat recovery has become an appropriate alternative. Welcome to the world of healthy respiration and energy efficient of living with WAFE heat recovery units.
