DuoTherm is a full-range supplier for exterior sun shading systems.

DUOTHERM GmbH, which was initially founded as a sales agency in 1998, has been manufacturing made-to-measure PVC-top-mounted roller shutter boxes since 2000, as well as the Thermo NB, a top-mounted roller shutter box system especially for new buildings. In addition, front-mounted roller shutter boxes and zip window awnings are also produced. Besides window awnings, DuoTherm offers venetian-blinds and roller shutters made of PVC and aluminum. Thanks to the in-house coating plant, profiles and plaster rails can be supplied in any available RAL colour. Above all, DuoTherm is characterized by finding suitable solutions together with the customer, even in difficult projects. The high service mentality of the 240 employees combined with high quality workmanship is what makes DuoTherm so successful.
