PVC Windows


The aCUBE system is characterized by visual perfection, modernity and simple contours resembling a cube. This proposal fits perfectly with the current trends in architecture and window joinery. It provides exactly the effect that investors expect: simple, minimalist windows, sometimes reminiscent of aluminum joinery. It is intended for the construction of windows, balcony and entrance doors.

The aCUBE system is distinguished by very good stability, perfect tightness, high thermal and acoustic insulation. All thanks to the multi-chamber structure of the profiles and the reliable system of the central gasket. The design of the third seal effectively blocks the heat flow. Many people are looking for a minimalist style, and thanks to the small depth of development, the aCUBE windows can be installed in both new buildings and historic buildings.

The aCUBE system is an excellent proposition for architects and developers because it maintains high thermal parameters at a moderate price.

Advantages of aCUBE:

  • a system adapted to the construction of windows, entrance doors and balcony doors,
  • simple contours from the outside and inside of the window,
  • high stability thanks to optimal steel reinforcements,
  • high acoustic insulation,
  • maximum glazing thickness up to 48 mm or 50 mm when using STV®,
