KUBUS – Modern PVC window and door system. Square and almost invisible.
The system dimension for both the frame/sash combination and the mullion is 100 mm. This means that the mullion and lateral frame parts have the same visible width, resulting in symmetry and an aesthetic appeal.
Continuous 100 mm sightline, including in the area of the mullion.
