Thermally broken sections
The new Builidings Energy Act (GEG), the increased environmental awareness and rising energy costs lead to the fact that planners, operators and end-users are more and more demanding windows with better U values. Particular attention is paid to this aspect, especially with the construction of low-energy or passive houses.
Multi-chamber profiles with up to 7 chambers and multi-glazing (up to triple glazing) with an argon or krypton filling make it possible to achieve better U values. However, sometimes this is insufficient and too expensive.
Our protected thermally broken sections now offer the possibility to reduce the U values of windows further and to achieve this without structural compromises, even in the case of large elements.
The thermally broken profiles consist of cold-rolled steel legs and a connecting polyurethane bridge, which is cast with the steel legs during production.
The IFT-certified thermally broken sections help to save energy and in doing so, conserve resources. They enable a Uf value reduction of up to 0.2 W/m2K to be achieved. In doing so, they significantly contribute to meeting the requirements of the energy saving regulation 2016 (EnEV)


- Production processes can be maintained unchanged
- No changes in the production process are necessary in order to build windows with different Uf values
- In comparison with equivalent steel reinforcing profiles, the structure is similar
- Thermally broken sections can be processed in the same way as conventional reinforcement sections. Machine modification is not necessary
- Identical characteristics during sawing
- Screw connections, which are otherwise performed in steel, can also be performed, as usual, in the plastic part of the thermally broken sections
