Thermal break aluminium system for casement openings

The EKU Perfektion, high performance window and door frames, have slender minimal lines, essential for contemporary aesthetics that aim at maximum luminosity while minimizing the visible surface of the profile.
The design of this stylish minimalist profile does not take away from the functionality and combines a refined quality of insulating materials with perfectly functioning integrated accessories, all incorporated within the profile itself.
The result is a greater glass area and a higher thermal and acoustic insulation that guarantee unparalleled comfort.



  • minimal design, obtained by minimizing the visible part of the profile wing (70 mm) and using integrated accessories
  • lower thermal transmission (uw) due to the reduced area of the profiles and increased glass area
  • superior quality materials, minimum maintenance and maximum luminosity
  • a wide range of profiles and finishings to meet every kind of aesthetic and constructive requirement
