The MB-77HS system is characterised by large dimensions of sliding system, huge panes and stable construction. The materials and technical solutions used help to achieve a high degree of thermal and acoustic protection. MB-77HS doors can be used to build 2- or 3-rail structures with a low threshold, thanks to which we obtain a very large space after opening the door. Thanks to their properties, MB-77HS doors are perfect for single-family buildings as well as for comfortable apartments or hotels.
