MB-77HS
Balcony lift-and-slide doors
Lift-and-slide doors are an ideal solution for developments that connect interior spaces or winter gardens with the outdoor environment, providing a comfortable exit to a balcony, terrace, or open garden area.
They ensure excellent visual and functional contact with the surroundings, and when open, they do not take up space inside the room, which significantly enhances user comfort.
The MB-77HS system is one of the products with the best performance parameters and fully meets all requirements for this product category.
