Flexible and sustainable

Innovative front door system

The extensive heroal D 92 UD system module allows you to design your own “calling card” for your home while at the same time achieving the highest standards in design, convenience, thermal protection, security, environmental sustainability and long service life.

Only high quality, environmentally friendly materials are used. The hwr powder coating guarantees excellent weather resistance. In addition to this, practically any colour from the RAL colour palette is available, opening up almost unlimited design possibilities. The thermal breaks are made from 62 per cent renewable resources. A controlled A/U/F recycling loop ensures seamless recycling.

A multi-functional fitting track guarantees the system’s flexibility: Thanks to movable fittings and the ability to backfit operating and comfort features, universal design can be realised without difficulty – even retroactively. Numerous door casement variations are available for enhancing the visual appearance. Combined with other elements from the system module, this opens up an immense variety of applications and design options.

The D 92 UD door system makes it possible for the first time to achieve a low heat coefficient of Ud = 0.8 – 1.8 W/m2K with an aesthetically appealing front door with concealed hinges. A patented, circumferential sealing system achieves excellent values for air permeability (class 4) and water tightness against heavy rain.

Machinemanufactured, corner-vulcanised internal gaskets guarantee high system reliability. The consistent reduction in the number of components has reduced the amount of effort required for installation as well as the servicing requirements and recycling costs, while improving performance and reliability.
