Solution for schools

A lot of schools has been equipped with new plastic windows and airtight insulation. Unfortunately, it has caused a significant lack of fresh air inflow. Doctors, hygienists but also media warn against this phenomenon. They compare schools to huge plastic bags where all students and teachers are held. Airless climate often together with the occurrence of dangerous pollutants such as radon or other harmful substances vaporising from the painted desks and furniture, present an unsuitable environment for students and teachers. Even in back in the days of Maria Theresa ventilation standards had to be followed in schools! Research has shown, however, that ventilation with windows is not sufficient under regular school circumstances nowadays. It is either too short or not intense enough and causes energy loss against which the schools invested in the first place. Simple solution how to provide continual fresh air influx, however, exists. WAFE offers a complex solution for schools, that ensures significant interior environment improvement. It is affordable, allows for subsidiary financing and helps fulfill the requirements of the current legislation.
