Composite windows

Our composite windows meet the highest standards for thermal insulation, privacy and airborne soundproofing. Composite windows are ideal for use in highrise buildings, office buildings, research centres and private residential buildings surrounded by busy infrastructure.

  • For buildings with the highest energy management standards
  • Improved condensation prevention in the space between the panes
  • The top profile of the blind is concealed so only a tiny proportion of it is visible when the blind is rolled up
  • Certified total package (composite window including solar shading)
  • Available with outer frame for renovation and integrated ventilation
  • The perfect partnership of soundproofing, thermal insulation and design
  • The blind runs sideways in the rebate to prevent sideways slants of light
  • The perfect blend of comfortable interior climate and stylish architectural design
