Convert your living room into a flexible veranda with the lift-and-slide system from UNILUX

Living room or patio? Stay inside, or get out in the fresh air? Why not both! The boundary between indoors and outdoors becomes fluid with the lift-and-slide system from UNILUX. Widths of up to 10 meters and heights of up to 3 meters ensure a seamless transition. And a whole new awareness of life. A free space – wide, open and adaptable at any time.

Three materials for the right lift-and-slide system, entirely the way you want it

We manufacture UNILUX lift-and-slide systems from fine wood & aluminum or robust PVC, optionally with or without a weatherproof aluminum shell. Regardless of the material that you choose, our lift-and-slide systems always meet the high quality requirements that we set for ourselves. Quality made in Germany, custom-made and adapted to your individual wishes.

Do you require barrier-free thresholds?

Our lift-and-slide system is the perfect solution: depending on the model, this also has a barrier-free option in accordance with DIN 18040*.

Energy efficiency

Large glass surfaces, but tiny energy consumption. The standard triple-pane insulating glass ensures a U-value as low as 0.8 W/(m²K). In plain English: In winter, most of the heat remains where it belongs – in the room. And vice-versa in summer.

Our different lift-and-slide system variants



Wood & aluminum HS lift-and-slide system

The lift-and-slide system that fits perfectly into your environment. With its clear, no-frills lines, it is perfectly suited to the wood & aluminum windows of the ModernLine. This creates a convincing overall architectural picture that simply looks great.

IsoStar Aluminum HS PVC & aluminum lift-and-slide system

Elegant aluminum on the outside, robust PVC on the inside, and a dream in glass all-round. The IsoStar Aluminum HS lift-and-slide system creates a completely new spatial effect for your house, optionally, even without any barriers whatsoever. And thanks to the outstanding workmanship, opening and closing is simply a matter of sliding.

PVC IsoStar HS lift-and-slide system

Timeless aesthetics at an affordable price. Make your dream of an open, spacious architecture come true with the IsoStar HS lift-and-slide system. It’s less a matter of “pushing” than gliding. Also available without barriers on request – for a unique spatial experience.

PVC IsoPlus HS lift-and-slide system

The narrow face widths of the frame (65 mm), the sashes (100 mm) as well as the center lock (103 mm) allow high levels of light penetration as well as solar heat gains. Glazing thicknesses of up to 50 mm can be installed in the IsoPlus HS.

Secure ventilation

Thanks to the integrated gap ventilation unit, the window can be opened to the width of the gap, while remaining locked. For safety and healthy air circulation.

Large selection of roller shutters, external Venetian blinds and more

For greater privacy, more security in rain and storms, and last but not least, maximum protection against break-ins, we also offer

roller shutters and external Venetian blinds for windows and doors. Whether for a new build or a renovation – we have the right product in our range. We also offer effective insect screens. This guarantees that every uninvited guest stays outside.
