Alumil Μ20650

M20650 is an insulated opening aluminium system which can combine both with European groove or PVC groove hardware. The basic feature of this system is that the outer frame completely covers the sash frame of the window, thus concealing it (“block window”)

  • Basic depth of system 62.5mm
  • Its unique design offers very good value for money ratio, as well as a small visible aluminium surface in harmony with the modern architectural trends
  • Sufficient thermal break zone is achieved with a glass reinforced polyamide of 24mm in the frame and also thanks to extra durable PVC double extruded glazing bead which blocks the heat transmittance.
  • Appropriate distance of 5mm between the sash and the frame for continuous application of sealing gaskets even behind the hinges
  • Glass thickness up to 24mm and sash weight up to 130kg
