A variety of solutions in one system

HST 85 mm doors provide a modular construction type which allows great flexibility in choosing configurations. This system is available in three different variants that can be adapted to thermal insulation requirements. From the economical version, through standard, to the premium version. Thanks to this, combined with the possibility of using energy-saving glass packages up to 51 mm wide, we achieve very high thermal insulation of the structure.


Superb tightness

Innovative system of overlapping catches equipped with rebate seals ensures proper tightness.
Introduction of HST 85mm deep sashes inspired us to apply further modifications of the sealing node.
An EPDM seal is used at the contact line between movable and stationary elements.
The change increased air tightness of the connection, although it requires slightly greater force to fully close the sash.

„Barrier-free” threshold variant

Door thresholds with a low height of 48 mm can be incorporated into the floor along their entire length. This allows them to be completely integrated with the floor surface. Additionally, thanks to special overlays, it is possible to align the threshold level with the floor surface, thus eliminating any architectural barriers



Many opening possibilities available

HST lift-slide doors are available in various versions and arrangements of sashes and non-opening parts. There are several popular HST door designs, including double-sash variants – with one or both moving sashes – and four-sash variants – with either two middle sashes or all movable. Thanks to this, having the opportunity to choose from these configurations, we can adapt the HST doors to the individual preferences and needs of the user.

Breathtaking views

Our HST patio doors’ advantage is their potential in terms of the size of the structure. The sash can reach as impressive width as 3.2 m and height of up to 2.7 m in white. Thanks to this, one can create glazing that is six meters long. We can seize an opportunity to use a lot of natural light and have a possibility of opening into the terrace or the garden.
