Description
A hidden sash window refers to a system where the sash — the movable part of the window — is completely concealed behind the fixed frame. This design increases the glass surface area by minimizing the visible aluminum profile.
Ideal for both new construction and renovation projects, this solution supports a wide range of applications and features one of the slimmest visible sections on the market, with a side node of just 74 mm. Despite its minimalist look, it delivers excellent performance, security, and ease of operation, and enables the creation of large glazed surfaces.
