DELITHERM® fabrics are energy savers both in the summer and in the winter. In the summer the drawn curtains reduce solar radiation by up to 55% and prevent the extreme heating up of rooms. Equally, in the winter DELITHERM® prevents the loss of heat through the window and keeps the heating in the room. One can save up to 15% of heating cost.
In both cases our fabrics help protect the climate. They reduce CO2 emissions because the use of air conditioners, ventilators and radiators can be reduced. DELITHERM® fabrics function similarly to sun protection systems but they are more durable, more easy care and more long-living. Above all, they are the homely alternative to the clean classic sun protection.
How does DELITHERM® work?
DELITHERM® fabrics are produced of high gloss special yarns. These effectively reflect heat radiation and thus give a comfortable room climate, independent of the time of the year. Tests performed by the Fraunhofer Institut confirm these properties.
