Disruptive innovation in a leaf design

Advanced Pro Edge technology allows glazing without the need for glazing beads. Thanks to this, more efficient glazing unit can be used.

Even more light

Both the frame and leaf profile are thinner than the standard system, which allows more daylight into the room. Patented technology of a Cube window gives you up to 10% more light than a traditional timber window.

Peace and quiet

Pro Edge technology enables the use of glass with great acoustic parameters.
