The Linear system is characterized by a minimalist design, which makes it a unique window.

Linear – modernity in a perfect line

 

Linear is an innovative PVC window system that combines minimalist design with high technical performance. It was created with modern architecture in mind and for clients who value simplicity of form, symmetry, and functionality.

 

The system is characterized by sharp edges and flush surfaces, creating a consistent, elegant profile line – both on the exterior and interior of the building. It is a perfect choice for modern homes, apartments, and residential developments where aesthetics, natural light, and user comfort matter.

Why choose Linear?

 

  • Minimalist form – clean lines, no curves, perfectly suited to modern architecture

  • Flush construction – frame and sash form a uniform surface with no protruding elements

  • Excellent thermal insulation – up to Uw < 0.80 W/m²K with the appropriate glazing unit

  • 6-chamber PVC system with 74 mm depth – a guarantee of durability and energy efficiency

  • Glazing possible up to 48 mm – for even better thermal and acoustic performance

  • Rich colour palette – timeless white, greys, wood-like and textured finishes

 

NEW: LINEAR LIGHT

 

In response to market needs, we have introduced a new variant of the system – Linear Light. It offers the same high quality, but with an even lower sash (8 mm lower), allowing for more natural light and an even slimmer window appearance.

  • Larger glass surface

  • Even more natural light indoors

  • More subtle, ultra-minimalist look
