The e4000 sophisticated insides of the frame and sash avoid metallic thermal bridges. Entirely free of foam inserts and special reinforcements that are thermally separated, it reaches outstanding insulation values and stability. The e4000 offers best insulation values in combination with an outstanding construction, so that safety, sounds insulation and design are equally respected.

With the system series e4000 was the first-time success to develop a heat insulating and at the same time cost-effective window – and that is completely without metal reinforcement inside the window system. This is achieved by combining two innovative technologies: bonding inside the bonding technology in the window sash and powder inside a new kind of U-PVC reinforcement in the window frame.


• Uf=1.1 W/m2k, while unprecedented
Uw up to 0.90 w/m2k can be realized.
• This top values results on the one hand from bonding the window sash with the glass pane and on the other hand rein forcing the frame.
• Filigree and classical profile design.
• Outstanding sounds insulation burglary resistance in the resistance (Wk2).
• Available in numerous decor variations and finishes.


• outstanding heat insulation
• no thermal bridges
• more light incidence thanks to leaner profile appearance
• the Uf-value improves due to the bonding technology and the flat U-PVC strips compared with the standard variant with steel profile around 20%to 1.1W/m²K at a depth of 70mm
• the profiles are approx. 60% lighter than their metal reinforced predecessors
• innovative technologies with a guaranteed future


eplus+ is available in more than 40 decor variations. Naturally, all colours feature the new cool-colors technology that sets new optical and technical standards. This technology guarantees considerably improved performance characteristics as wellas a longer life span of the surfaces. The cool-colors decors are provided with patentedspecial pigments that measurably reduce the surface temperature of laminated windowsystems. By this means, function and design are perfectly combined.Aluminium clips complete the system serial. They are available for any variation andmake higher element heights possible thanks to their special clip function. For more color options Click Here.
