The energy efficiency of buildings plays a central role in the context of sustainability and climate neutrality, since most of the energy required in Germany is used to provide heat. The use of air conditioning and heat pumps for cooling in summer is also becoming increasingly popular. Sun protection systems installed outside can save a lot of energy and significantly enhance the energy efficiency of a building. In winter, the sun light is used to increase the energy input into the building and thus minimise heating costs. The air in the gap between the window and the lowered blinds serves as an additional insulation and keeps the heat inside the building. In summer, rooms without blinds can quickly overheat. A textile sun protection installed outside reflects and absorbs the sun’s rays even before they strike the glass, thus preventing the interior from heating up quickly. If the room has an air-conditioning system, further potential savings are possible, as the need for cooling is significantly reduced. Standard heroal textile screens are equipped with a motor, offering you additional options to reduce energy consumption as much as possible by adding a timer or a weather station with sensors.
