Our AluClip Zero system is a design variant unique on the market and has already been tried and tested in several building projects.


This system comes in three variants; One presenting a completely flush-mounted look and virtually flush glazing plane, a second with a classical wood-aluminum look and the same glass plane as fixed glazing, and the third variant with all glass look where the window sash and pane are virtually flush-mounted.


Designed specifically for demanding architectural projects, it can bring its advantages to bear exactly where the aluminum look is just as important as the functional benefits of uPVC.

Different U-values are possible depending on the frame/sash combination, glass, and steel insert. Contact us for more details.
