Superial SU
SUPERIAL SU is a three-chamber window system with thermal insulation designed for windows with hidden sash, invisible from the outside. The system features specially designed shape of the frame hiding the full height of sash profile.
The hidden sash system is preferred by designers, as it allows “hiding” windows in aluminium and glass structure; thanks to the application of this solution, openable and fixed window constructions look identical from the outside.
