Questions about MB-86 Fold Line HD
Can doors open both inwards and outwards?
The system supports both principles. The actual layout depends on opening size, available indoor and terrace space, and threshold details.
Can every project have eight leaves?
Up to eight leaves is a system capability. Leaf count, individual dimensions and weight must be approved for the layout and glazing.
