    For whom?

    The folding exterior doors give great freedom to users. They can easily take advantage of favorable weather conditions and almost literally eliminate the barrier between the interior and the surrounding area.

    The door can therefore be a perfect, wide passage from the house to the terrace or a combination of a café or restaurant with its seasonal outdoor area.

    The MB-86 FOLD LINE system is a very convenient solution in everyday use and at the same time has high technical parameters and allows to make structures of large dimensions. Folding doors can be opened both outside and inside the building, and can have any wing configuration. It is a modern product, designed to meet the high requirements of users, architects and investors.
