Patio Doors

Sliding elements are a classic stylistic feature in modern living, with generously designed glass surfaces conveying a sense of comfort and elegance. The S 8000 lift-slide door more than meet these requirements, both visually and functionally.

The New Lift-Slide Door
Our Standard Patio Doors

Comfort at Home Made Easy

Large door elements can be moved with ease with our technology. It does not matter whether the door is open or closed. Either way, the room is flooded with light. And the virtually threshold-free floor junction further offsets the separation between the interior and exterior.

More Light Than Ever

Do you enjoy a large glass area and more light when it comes to lift-slide elements? Then GEALAN has a very special technical solution for you. Its visible width in the fixed section is more than 50% smaller than the normal lift-slide sash.

Maintaining Space Climate

Top heat insulation values

Even the standard version of the new lift-slide door with standard stiffening elements and no additional measures achieves a very good calculated heat insulation value of Uf 1.3 W/(m²·K).

Triple glazing

Modern triple glazing up to a thickness of 52 mm (STV® 54 mm) can be used with ease in the new system.


Featuring a modern design, narrow sash and innovative glazing profile for more glass in the fixed section.


Thanks to the best heat insulation values even in the standard versions, superb workmanship and innovative technical solutions.

GEALAN-acrylcolor® surface

Lift-slide doors with the proven GEALAN-acrylcolor® surface boast a durable and uniform surface quality. They offer huge design freedom for new builds and renovations.


Thanks to various design options, different types of opening mechanisms and a wide range of color options for the surfaces.
