HENSFORT PE78N aluminium window

Lightness, durability and modern design are the features of the HENSFORT PE 78N aluminum system, which are particularly valued by investors not only in business, but more and more often in single-family houses and modern passive houses.

Shaping system with three-chamber profile structures with a fitting groove used in windows and balcony doors made of PVC profiles. The structural depth of sections for frames is 78 mm, and for sashes  - 86 mm. The use of multi-chamber 42 mm thermal separators  and a two-component central seal allows high thermal insulation. The system allows the installation of glass fillings (single and composite glazing) or non-transparent panels with a thickness of 17-61 mm. In the PE78N version, the frame heat transfer coefficient is from 1.7 W / (m² · K). In the warmer version PE78N HI with the lock of the under-glass chamber and insulating insert Uf is from 0.9 W / (m² · K).

The three-chamber structure of the PE78N system profiles ensures high stiffness of sections, and thus enables the construction of large-size structures. PE78N allows you to make corner joints, both creased and twisted.
