A semi-permanent secondary glazed window is an independent window that’s fitted on the inside of an existing door or window, usually not operational. It’s ideal when space is limited, or when minimal access to the primary window is required. For this reason, our lift-out units are incredibly popular in large-scale commercial projects.

Its own “shuffle” glazed frame fits into our face or reveal fitted “parent” subframe. It “shuffle” lifts out for occasional access. Size and weight is the main consideration; from the physical lifting point of view.
