Door leaves and frame surfaces are on the same plane (the installation space for the fittings is 18 mm). The PE 78N system uses a 34 mm wide thermal insulator. Specially designed connecting profiles make it easy to connect the door to the showcase. The offer includes different threshold solutions (also a threshold made of PVC), which not only seals the threshold by draining water to the outside, but also stands out with higher thermal insulation. An additional advantage of the HI system is increased heat insulation, which is achieved by using special heat-insulating inserts.

It is possible to achieve Uw=0.93 W/m2K for PE78 HI exterior doors (Data achieved in construction with size L=1230 x H=2180 mm, with triple glass panel Ug=0.5 W/m2K)

• Three types of heat transfer solutions - Standard / "+" Solution / HI solution
• Various options for the execution of door leafs: Connection of the leaf corners at an angle of 45 degrees, at the bottom part of the leaf is connected at 90 degrees, with profiles of different widths, with or without a threshold
• Curved/arched constructions can be made
• Possibility to install roller hinges, hidden hinges
• It is possible to insert double and triple glass panels, as well as opaque panels with a thickness of 23-61 mm
• The construction depth is 78 mm
• The possibility of incorporating different types of locks (single or multi-point fixation, access control, escape door equipment, smart home solutions, etc.)
• Hardware: The most famous brands are used: Fapim, Savio, Isea, Cisa, Geze Dorma, etc.
• Surface coatings - polyester powder coating according to Qualicoat. Available in all RAL colors; anodized and with a wood-like appearance; Polyester powder coating meets the highest anti-corrosion requirements
