Cortizo 80

COR80 is a window and door system with a large width of the frame profiles 80 mm. The 45mm wide thermal break applied in the profiles provides very good thermal insulation parameters, which allows achieving a Uw coefficient even 0.8 W/m2K. Minimal permeability and excellent water tightness make it an ideal solution for harsh climatic conditions. The possibility of using width glass up to 65 mm allows the use of triple-glazing with different construction. It affects the maximum energy saving and acoustic comfort inside the room. The system allows you to design modern window construction solutions in many variants – windows (unopened, turn, tilt and turn), external doors and various types of shop windows.

  • Standard triple glazing with Ug value = 0.6 W / m2K filled with noble gas – argon, with a warm edge spacer (Chromatech Ultra)
  • A wide range of glazing up to 65 mm allows you to use all types of glass – standard, safe laminated or tempered, soundproof (up to 53dB!) *
  • The possibility of using solar control glass with parameters Lt = 39% and g = 23%
  • Possibility of incorporating hardware with concealed hinges & the security system Evo Security
  • A wide selection of colors – RAL palette, bicolor, anode
