Concealed sash window

A concealed sash window is a type of window where the sash (the movable part) is hidden behind the frame (fixed frame) when closed, offering a more sleek and modern aesthetic thanks to fine lines and maximised glazing.

Unlike a visible opening window, where the sash remains visible even when closed, the concealed version optimises light and design. This concept is particularly suitable for contemporary projects or those wishing to highlight large glazed areas.

In addition to its style, it maintains the same thermal and acoustic insulation performances as its visible sash equivalent.
