Lift-and-slide terrace doors (HST 85)

Large PVC sliding doors that lift slightly, then glide aside — more glass to the terrace, no swing space indoors.

Why buyers choose HST

• Wide openings for terrace and balcony without a classic swing door in the room

• Room for energy-efficient glazing up to 51 mm

• Three thermal build levels (Basic / Standard / Premium) so you match insulation to the project, not one “max” claim for every size

• Low 48 mm threshold that can be recessed or leveled with the floor for easier access

• Opening schemes A, C, D, F — one or two moving sashes, two- or four-pane layouts

• Optional Fixframe: a slimmer frame on the fixed lite for more glass and light

How it works: The sash lifts a little on the hardware, then slides on the track. When closed, overlapping profiles and gaskets help keep the joint weather-tight. Sizes and schemes are chosen per opening.

Colours: Decorative foils and aluminium-look (aluskin) finishes from the Aluplast range — exact codes confirmed per order.
