Balcony folding door Bi-fold

Folding balconies are constructions most frequently found in Great Britain and Southern European countries.

Bi-fold balconies are characterised by an innovative opening system that guarantees an amazing effect of open space. Complete sliding of the sashes optically enlarges the interior and ensures uninterrupted contact with nature. Thanks to perfectly matched BRIO fittings, their manning is a child's play. 

Folding systems are used in private homes and public facilities. We also meet them inside buildings in order to separate two parts of the room.
