DELITHERM® - Our textile contribution towards reducing CO2 emissions

Energy saver made of metallised yarn - soft drape and washable

DELITHERM® fabrics are energy savers both in summer and winter. In summer the drawn curtains reduce solar radiation by up to 55% and prevent the extreme heating up of rooms. Equally, in winter DELITHERM® prevents the loss of heat through the window and keeps it in the room. One can save up to 15% of the heating cost.


In both cases our fabrics help to 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, easy to clean and long lasting. Above all, they are the cosy alternative to the clean classic sun protection.




How does DELITHERM® work?

DELITHERM® fabrics are made of high-gloss special yarns. These effectively reflect thermal radiation and thus ensure a comfortable indoor climate, regardless of the season. Tests conducted by the Fraunhofer Institute confirm these properties.

NEW | Gamma Colour DELITHERM® | The darkeners

Gamma Colour is the colour-printed version of the proven Gamma article. The dimout-based reflective satin fabric made of 100% polyester FR is colour-printed on the side facing the room, while the reverse side facing the window retains its reflective sheen and thus fulfils the energy-saving function.


NEW | Solis DELITHERM® | The structured one

Solis is an opaque decoration fabric with a highly reflective reverse side. Made of high-gloss polyester FR special yarn, Solis has outstanding solar values, which always ensures a pleasant indoor climate. The vertically accentuated melange is available in 10 colours, including 5 natural shades as well as 5 bold shades for educational use. 
The fabric is 140 cm wide and has a good light fastness of 5-6. Solis is not only good for use as a curtain, but also as a folding blind.

NEW | Save DELITHERM® | The Functional

Save is a pure thermal fabric that achieves its reflective effect through titanium oxide firmly embedded in the yarn and reflects UV rays particularly effectively. These energy-saving properties are effective on both sides of the fabric.
The semi-transparent Jacquard knitted fabric offers a pleasant light transmission and at the same time protects privacy. With a sound absorption coefficient of αw = 0.35 (Class D), this innovative fabric also ensures good room acoustics.
Polyester was used in combination with 30% recycled material in the production, which further reduces environmentally harmful emissions, apart from the already energy-saving function. Flame retardancy is achieved through an FR finish.

Alpha DELITHERM® | The transparent one

Alpha is a DELITHERM curtain that lets daylight into the room even when it is closed and effectively reflects UV rays. This greatly reduces the heating of the room by the sun's rays and keeps warm air in the room in winter. With a sound absorption coefficient of aw 0.3, our thermal curtain also ensures a quiet atmosphere.

Eos DELITHERM® | The Basic with smooth surface

Eos is an opaque curtain fabric. It has a smooth, closed surface and is available in white. Good acoustic values of sound absorber class D prove its sound-reducing effect.

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