Lift and slide doors are the perfect solution for connecting rooms, such as rooms or conservatories, with outdoor spaces. They provide a practical transition to the balcony, terrace or garden, while offering great contact with the outdoors. When they are open, they do not restrict the space inside the room, making them more comfortable to use.

The MB-77HS system is one of the highest performing products, meeting all expectations associated with this product group. It is available in two different construction versions in terms of thermal insulation: ST and HI. The structure of the profiles allows the creation of large, exclusive doors, filled with single or double glazing. The materials and technologies used guarantee a high level of thermal and acoustic insulation.

Thanks to its advantages, this system is ideal for single-family buildings as well as luxury flats or hotels.
