Modern architectural designs involve some very large glazing of external façades. In order to successfully tackle these challenges we have manufactured the following terrace door units:
HST PVC (lift and slide) terrace doors
The HST lift and slide system
The basic advantage of the HST system consists in a possibility to manufacture constructions up to 6 metres spread with up to 3000 mm wide leaves, which allows to glaze a nearly entire wall. Turning a handle allows to lift a leaf by several millimetres, release pressure and freely slide the leaves. A possibility to use up to 51 mm glazing package allows for high thermal insulation parameters. HST type doors are available in several versions and systems of leaves and unopened parts, which allows for nearly infinite construction possibilities.
