The system is used to construct windows, doors and showcases with high thermal insulation parameters for use in residential, public and industrial buildings.

The thermal insulators used in the system (made of glass fibre-reinforced polyamide) and the space between them is additionally filled with polyurethane foam. The system makes it possible to create large-size structures due to the use of reinforced profiles on the outside as well as on the inside.


  • optimisation of building operating costs through increased thermal insulation of profiles,
  •  the possibility of realising modern window construction solutions in various configurations,
  •  bendable profiles,
  •  the possibility of installing windows in façade systems,
  • possibility to build sets of structures combined at any angle
  •  the possibility of using a full range of modern fittings and individual handles or catches thanks to the use of different profile widths,
  •  possibility of using concealed hinges and remote-controlled locks thanks to the profile widths used,
  • split thermal breaks to eliminate the bimetallic effect,
  • Can be combined with other Yawal systems.
