Concealed-sash PVC windows: a consistent exterior line
Cortizo A 84 concealed-sash windows hide the opening sash behind the frame for a minimalist exterior similar to fixed glazing. A Passivhaus option adds high thermal performance.
Only 90 mm of visible profile
Fixed and opening sections show the same 90 mm exterior profile, helping the façade look consistent. Reducing the visible frame leaves more of the same opening available for glazing and natural light.

Concealed hardware options
Options include concealed hardware, a concealed handleandconcealed drainage. We check availability and compatibility for the selected opening configuration.
Coordinate fixed, opening and sliding glazing
A consistent visible profile lets fixed and opening sections sit together on the façade. The specific frames, joints and dimensions are assessed as one design.
For terrace access, a separate system such as Cortizo E 170 lift-and-slide can be considered where larger glazed openings are needed.
Frequently asked questions
