Terrace without barriers
HST is a lift-and-slide system — the sash lifts above the threshold and glides effortlessly, even at 3–4 metres wide. Low threshold, tight sealing and good Uw values make it ideal for energy-efficient and passive houses.
If the opening is smaller and the budget tighter, PSK (tilt-and-slide) does the same job for less. We advise which option makes sense for your project.
