HST Passiv Lift&Slide doors with 85 mm leaf depth and 197 mm jamb depth have been designed for unlimited freedom of space creation.

HST lift and slide doors meet the three criteria most requested by customers:

TIGHTNESS – the system based on the profile of market leading brand Aluplast is one of the most impermeable solutions in its class. During the sealing tests it achieved a perfect result – class 8A (450 Pa). Thanks to this, even during the most extreme weather conditions HST Passiv will perfectly fulfill its task.

THERMO-INSULATING POWER – when using deep casement development we can use very “warm” pane packages (Ug 0,5 or 0,6 W/m2K), thanks to which we achieve excellent thermal insulation power. Depending on your needs, to achieve the lowest possible Uw value dedicated to passive and zero energy houses, we propose a solution using the HST Passiv system.

LARGE DIMENSIONS – HST Basic and HST Passiv also meet another demand of the construction market, allowing for the construction of windows in this class with maximum dimensions of 6000mm wide and 2500mm high. Thanks to modern machinery we can offer you the production of these windows in any available color, regardless of the window system you decide on using our offer.

HST lift-and-slide doors can come in at least a few different versions and arrangements of wings and non-opening parts.
