What Is a Hidden Sash Window?
A hidden (or concealed) sash means that when viewed from the outside, the sash is completely invisible and flush with the frame. The result?
- Larger visible glass area
- Slim sightlines for cleaner views
- Sleek modern look with no external sash profile
- Ideal for high-end contemporary architecture
This system blends seamlessly into the facade for a truly minimalist exterior.
