The modern aluminium system for designing windows and doors requiring very good thermal insulation

Thermal separator 45 mm deep, made of solid and proven materials, is an effective thermal barrier

The same type of insulation insert in the window sash and in the window frame provides continued protection against heat losses of the whole structure

New standard of profile and glass pane interface – increased depth improves thermal properties and structure of the system

New type of corner section used preventing collision between the screw and the corner when screwing in surface hardware elements under the PVC groove

Possibility of adding roller hinge system hardware with very high load bearing capacity

Innovative drainage system (no visible elements stopping drainage outlets)

The same type of corner and T connector in the external and internal cavity (reduced number of accessories, faster fabrication)

Reduced number of glazing strips and gaskets, while keeping the continuity of glazing depending on package thickness

The ystem is particularly recommended for low energy consumption and thermal insulation retrofitted buildings, and they also improve thermal comfort in standard object

A wide range of colours available – RAL palette (Qualicoat 1518), structural colours, Aliplast Wood Colour Effect (Qualideco PL – 0001), bi-colour, anodized (Qualanod 1808)
