Our textile contribution towards reducing CO2 emissions

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.

  • DELITHERM® fabrics are usable as:
  • sheers
  • curtains
  • linings
  • roman blinds
  • panels
  • DELITHERM® summarised briefly:
  • energy saving thanks to the reflection of light rays and heat
  • reduction of CO2 emissions
  • washable at 30°
  • soft drape
  • hard wearing in daily use; unlike with coated sun protection qualities there are no crease folds
