HST sliding doors are a very innovative solution in the context of joinery products. They allow to create in each building very large glazing areas. This gives a feeling of a larger and brighter room, eighter a living room, or an office – just a sense of comfort and functionality.  Such technology provides a remarkable lightness to sliding sashes, regardless of the width of the entire door. This solution is ideal for creating entrances to the different parts of a house or outdoor: garden or terrace. HST sliding doors are ideal for all new buildings, as well as for the restorated ones, when customers want to get more space and have more light in the room, thanks to large glazed surfaces.
