HST sliding doors are the only window structures that allow the creation of large-scale glazing while providing great comfort. Sliding terrace windows blur the boundary between house and garden. This, on the one hand, provides excellent room illumination and, on the other, optically adds spaciousness.
An unquestionable advantage of this type of patio door is the feasible dimensions of the construction. The width of the leaf can range from 800 mm to 3,000 mm in width and the height up to 2,700 mm in white, which allows the creation of even more than six metres of glazing.
A distinctive feature of the HST 85 door is the modular nature of the construction, which allows three free configurations of the product, depending on the expected thermal performance.
Thanks to the freedom of choice of different combinations of profiles in the lintel part of the door and in the threshold part, we can choose between three options: Basic, Standard and Premium.
Combined with the possibility of using energy-efficient glazing packages with a width of up to 51 mm, this makes it possible to achieve a very high thermal insulation of the structure.
The low door threshold of 48 mm, which can be recessed from the room side to its full height, meets the requirements for barrier-free construction and allows trouble-free entry and exit.
Thanks to special overlays, it is also possible to flush the threshold with the floor surface and thus completely eliminate architectural barriers.
