HST aluminum patio doors

The innovative lift and slide door on an aluminum profile offers maximum thermal insulation and an increased range of glazing options, also available in a modern corner option.

Comfortable and light operation of the door is ensured by a functional opening system that gently lifts the sash moving on special rollers. This makes sliding the door effortless. The doorstep can also be flush with the floor from the inside, making it much easier to move between the interior of the house and the patio or garden. Aluminum profile allows the construction of exceptionally large glazing, which maximally illuminates the interior, giving it a spacious and premium character.
