Yes. We offer several shading solutions to achieve the desired effect. In addition to concealed, enclosed shutters, automated strip curtains can also be installed.

What are the biggest advantages of wisiow windows?

Wisiow sliding doors and fixed windows combine timeless minimalist aluminium frames with the largest possible glass areas of up to 18 sqm through their unique design.

Is the frame really invisible?

The aluminium frames of the sliding doors and windows are concealed in the floor and ceiling. Only the 1-4 mm horizontal and 24 mm vertical profiles are visible. But even this is almost invisible compared to the size of the window surfaces.

The Wisiow frameless system is also available with a hidden rail. In this case, only an elegant small gap in the floor is visible in place of the open sliding track.

Minimal frames and the quality glass they contain have been designed to be installed anywhere in the world, to suit local conditions from Dubai to Scandinavian countries.
