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.
