A modern, minimalist window system with simple contours.

Straightforward design language

The system is based on a consistently sleek design language that is currently setting the tone in architecture. A range of matching glazing beads continues the consequent design of the exterior appearance also on to the interior side of the windows. Slim face widths in the frame and sash provide more light in the buildings.

Tapping into the full potential

Whether in new construction or renovation, LINEAR impresses with its broad versatility. It is a complete system platform that includes windows, front doors and sliding doors. It can be expanded with the BERTRAND innovation of the STV bonding technology.

Stylish and timeless

The clear, angled design of LINEAR has a refreshingly timeless effect and is in keeping with the modern architectural language. Especially in new buildings, angular forms and clear lines determine the trend towards open and quietly designed facades.
