SlimLine 38 is an advanced aluminium system designed for modern architecture that prioritises maximum interior daylight, slim profiles, and top-class aesthetics. Thanks to its exceptionally narrow frame sections, SlimLine 38 makes it possible to create glazing that appears almost fixed while maintaining the full functionality of operable windows.
The system is available in four aesthetic variants:
- Classic – timeless, balanced appearance, suitable for most architectural styles
- Ferro – industrial aesthetic inspired by steel, ideal for renovations and lofts
- Cubic – geometric form with clearly defined lines, for modern designs
- Functional – a classic, simple profile with a universal character, popular in residential construction
Each of these versions allows the joinery to be adapted to the investor’s individual expectations or the project’s requirements.
