Eforte System


Featuring a profile depth of 84 mm, a conventional steel reinforcement and without additional insulating elements, Eforte accomplishes a unique Uf-value of 0.95 W/m2K. The current requirements set out in the Energy Saving Regulation and the values required for entitlement to KfW financial support (German Reconstruction Loan Corporation) are met with ease. The passive house standard (Uw ≤ 0.8 W/m2K) can also be implemented cost effectively with standard triple glazing. Eforte is the only system without additional insulation to be certified as a passive house suitable component by the internationally renowned ift Testing Institute. Besides outstanding thermal insulation the Eforte system offers a hitherto unmatched flexibility and can adjust like a chameleon to meet your every need: floor to ceiling height of the window elements up to 2.6 m are possible thanks to the Inoutic bonding technology, a glazing thickness of up to 56 mm can be accommodated for special safety glass or acoustical insulation and a vast selection of colours and decors allow you to create your own individual style. You can even design the facades of passive houses to meet your individual needs. Create a true aluminium look without having to sacrifice the benefits of a PVC window by using the aluminium cladding with butt-jointed corners. The aluminium frame can be designed in practically any colour you desire. The intelligent design of the Eforte profile is suitable for installation in old and in new buildings.
