Tilt and Turn Hidden Sash

Hidden Sash Tilt and Turn

The Tilt and Turn Hidden Sash is a stunning contemporary aluminium window system with slender profiles. The unique hidden sash feature makes the window look like a fixed light when looking from the outside. This technique is optimal for modern applications and also works in traditional buildings.

As the aluminium profile is so slim (66mm) this window system allows to maximise the glazing area (up to 85% visible glazing) and let plenty of light into the room. The slim line design enables to hide the frames from the outside, so that it is impossible to tell the fixed areas from those which have an opening.

Designed for both the domestic and commercial market the Aluminium Hidden Sash Tilt and Turn window is suitable for all type applications.
