AluFusion System

AluFusion is a new type of window and residential door system with 70 mm construction depth whose predominant property lies in the union of aluminium and uPVC. Besides the familiar functions of an aluminium cover, the special features of AluFusion include in addition the sliding connection between the functional aluminium and uPVC sash profiles and the absent glazing bead.


Based on structural glazing technology.The future of the modern window has begun.

GlassWin is a 70 mm window system used in the production of innovative uPVC windows.

This system features a bond between the pane and the frame structure, a technology known from frame construction. The principle is an adhesive join that transmits forces and reinforces the window sash with a stepped insulating pane. As a consequence, elements for uPVC windows can now be manufactured in sizes that earlier were possible only with considerably larger profile dimensions.
