HST lift and slide patio doors are available in several versions and wing systems. Variety of constructions is an undeniable advantage of this solution.

Popular HST doors schemes are: 2 sections with one or two moving wings; and 4 sections with two middle or all moving wings. Up to 6m wide and 2.5 height.

Specialized window fittings ensure that wings move freely and without any resistance. Modern architecture relies on large-format windows that are secure, comfort, stylish and energy efficient. 

The HST lift and slide systems can be made up to 6 meters wide and 2.5 meters  high. Turning the ergonomic handle down, from its closed position, lifts the sash a few millimeters, releasing the pressure of the seals and making the door slide easier. 

Sashes move easily without any resistance, relative to each other or with respect to non-open parts of the structure.
