ASP HS 75 lift and slide doors are an interesting alternative to traditional balcony doors. Thanks to them, there is a possibility to use very large glazing that, when opened, does not take up space. The leaf moves parallel to the other. This system allows the use of much larger dimensions than windows or traditional hinged doors. ASP 75 HS system enables the creation of one, two, and three-track constructions and corner connection of two lift-slide constructions. Thanks to the well-thought-out and functional structure, even large-sized doors can be opened and closed smoothly. The use of the ASP 75 HS system allows to get an open space between a fixed part of the building and, for example, a winter garden and maintains the individual style and functionality of each room.
