Building System Solutions



  • 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
  • possibility of glazing from the inside
  • option of bending profiles (detailed specification of profiles and detailed technical parameters of profile bending process are available in the customer area of the website
  • modern design
  • the system 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)
