A special aesthetic

The concealed sash, with its very discreetly visible, sleek leaf frame in black, merges seamlessly into the architecture and thus creates a special aesthetic.

When viewed from the exterior, the sash profile is practically invisible, placing even greater emphasis on the glass surfaces. This minimalist design comes hand-in-hand with even greater light transmittance and hence, a further improved living atmosphere.

Window handles –

aesthetically pleasing, comfortable and safe

Our window handles with their delicate, restrained forms create an aesthetic gain in terms of a holistic object design. At the same time, they offer a secure way to lock your windows. Both versions of the handle lock in the 90° position. Handles with operating locks are unlocked by pressing and turning the handle at the same time thanks to their practical one-handed operation.


On the second model, the operating lock is actuated by means of a release button, and the window can be opened or tilted by pressing and turning the handle at the same time. Two-handed operation is required. No key is needed for either version.

The five aluminum models are available in the following colors:

Black, sand-blasted anodized
Medium bronze, sand-blasted and anodized

Interior design variants

The PureLine system fits perfectly into modern buildings and enables a wide range of architecture solutions at the highest technical level: In combination with tilt and - turn/fixed glazing, the different elements combine almost invisibly according to the “Less is more” principle, and are therefore almost indistinguishable. And with the option of integrating the interior of the window flush, you can also create a harmonious look between inside and outside areas.
