Window profile system Eforte /

Uncompromisingly top class for energy-efficient living

With the Eforte profile system, we attach special importance to modern thermal insulation because efficient energy saving is one of the most important challenges of today. With a mounting depth of 84 mm, Eforte achieves an outstanding Uvalue of 0.95 W/m²K with ordinary steel reinforcing and without additional insulation measures. In addition to the usual gaskets, an innovative gasket in the glass rebate provides even better insulation.
Special glazing for particularly thick safety glass or soundproof glazing are available up to 56 mm. A wide choice of colours and decors covers all design requirements. The intelligent concept behind the Eforte profile means that it can be used in both old and new buildings. It goes without saying that the right front door is also available to match your Eforte windows.

Eforte window in aluminium-look

An aluminium capping gives a genuine aluminium look with butt-jointed corners − without sacrificing the energy-saving advantages of a PVC window. The aluminium capping can be designed in almost all colours to suit your requirements.

Innovative decor foils with an aluminium look can be used as an alternative. When combined with anthracite-coloured window profiles, your PVC windows look appealingly similar to aluminium windows and blend harmoniously into your property's overall architectural appearance.

New passive house constructed in the traditional style provides stunning views

For the construction of the new Arberseehaus restaurant in the Bavarian Forest in Germany the architects chose a traditional design and combined this with a very high level of energy efficiency. Inside, the restaurant features windows and doors with an oak look, while outside the moss green colour blends in perfectly with the traditional façade style and the surroundings. Special glass sliding elements were also developed for the large, easy to operate windows, which allow stunning panoramic views over the lake.
