HST lift and slide doors meet the three criteria most expected by customers:
TIGHTNESS – the system based on the profile of the market-leading Aluplast brand is one of the most impermeable solutions in its class. During the tightness tests he achieved an excellent result – class 8A (450 Pa). Thanks to this, even during the most extreme weather phenomena, HST Passiv will fulfill their task perfectly.
THERMAL INSULATION – using deep wings, we can use very “warm” glazing (Ug 0.5 or 0.6 W / m2K), thanks to which we achieve excellent thermal insulation. Depending on your needs, to achieve the lowest possible Uw value dedicated to passive and zero-energy houses, we suggest choosing a solution using the HST Passiv system.
LARGE DIMENSIONS – HST Basic and HST Passiv also meet the subsequent demand of the construction market, allowing the construction of windows in this class with maximum dimensions for a width of 6000 mm and a height of 2500mm. Thanks to the modern machinery park, we can offer you to make these windows in every available color, regardless of the window system you choose using our offer.
HST lift-slide doors can be in at least several different versions and arrangements of sashes and unopened parts.
