Above all, the highest level of functionality is expected from a window. They should provide an appropriate level of protection against burglary and, in addition, guarantee thermal comfort to the inhabitants and dampen noise coming from outside.

Our offer includes windows made of various materials – wood, aluminium or PVC. Depending on the material used, the windows are distinguished by different properties. Each solution has its own advantages.

We offer PVC window profile models with properties:

  • profile depth: 70 mm / bumper seal
  • 5-chamber system (70 mm frame)
  • heat transfer coefficient value: Uf= 1.3 W/m²K (standard reinforcement)
  • energy saving: up to 56% (comparative base – wooden windows withUw= 2.7 W/m²K
  • sound insulation (VDI 2719) / Rw: up to class 4 / Rw ≥ 42 dB
  • Burglar resistance (ENV 1627): up to class RK 3
  • air permeability (EN 12207): up to class 4
  • rainwater tightness (EN 12208): class 9 A / E750
  • modern corner profiles are also available, minimising the possibility of condensation.

and aluminium profiles with properties:

  • The structural depth of the window sections is: 70 mm (frame), 79 mm (sash), and doors respectively: 70 mm and 70 mm.
  • The shape of the profiles makes it possible to obtain slim and resistant window and door constructions.
  • variety of window functions, adapted to the needs of users
  • possibility to bend profiles and build arch windows
  • single or double-leaf doors, opening to the outside or to the inside, including the doors with the so-called “safe swing”.
  • basis for solutions with increased thermal insulation
