Topas

Topas is exceptionally flush-mounted on the exterior. The seamless alignment with the glass pane gives the window a refined appearance, emphasizing the clean and elegant architecture of your home.

Topas is offset on the interior and features a beadless design. Combined with its slightly beveled window edge, it creates a contemporary look with an intriguing sense of depth.

Less frame – more daylight. Over 12% slimmer compared to similar current window systems.

Using 80% recycled PVC, we focus on sustainability without compromising quality or design. The surface is radiant white and made from virgin PVC.

The beveled sash design on the interior looks contemporary and blends perfectly with simple, modern interior styles. Matching handles further accentuate this look.

Effortless cleaning thanks to easy-to-clean profile contours without a dirty joint.

Renovations are usually a major intervention in the façade of the house. Topas counteracts this, as it can be installed with a slimmer system thickness even in older houses with narrower outer walls.
