The PI 50N System is used to construct thermo-insulated windows, external development cabinets for external development in residential, public service and industrial buildings. 
The system enables the construction of the following:

  • solid windows,
  • tilt-and-turn windows,
  • tilt windows,
  • turn windows,
  • multi-sash windows,
  • windows with solid posts,
  • windows with movable posts,
  • windows with hidden sashes,
  • turn and sliding windows,
  • anti-burglary windows.

The PI 50N system consists of three-chamber aluminium profiles with a thermal separator.
The casing depth is as follows:

  • frame -50 mm
    leaf -59 mm

The PI 50N system may use a variety of fill types (insulated glass, also in 13-40 mm three-pane packages).

The sash, post and crosspiece dimensions must be determined based on static calculations, with regard to wind load, aluminium profiles resistance characteristics, glazing type and permissible bents of balcony door and window elements.
The maximum width of tilt and tilt-and-turn sashes equals 1500 mm, the height 2400 mm, the maximum weight 130 kg. Extra profiles enable the construction of combined windows performing different functions combined in free sets. 

The system allows for the construction of large structures due to its use of strengthened profiles in external and internal layouts. Angle profiles allow for the construction of sets of structures at considerable angle. A wide variety of specialist profiles enables the construction of windows of very good thermal parameters, proper size and the free arrangement of different window types. The aesthetic values of the structure are stresses by the high quality of profile finish surface: powder varnishing in wood base colours and anodising.

The system may realise modern window structure solutions in multiple configurations and layouts. It enables window installation in facade systems. It also has a unique system of triple insulation.

The PI 50N system windows allow for the optimum construction of building elevation structures, considering special needs of users as far as the functions, aesthetics and durability. 
The solutions provide a building with individual style, ensure the implementation of the architectural concept applying an economical solution.

The usefulness of the product called YAWAL PI 50 system balcony doors and windows in the construction branch has been certified by the ITB AT-15-4201/2006 Technical Approval
