Lift + slide doors
Choose between two Fenstür lift-and-slide systems: the versatile Climatech platform or the minimal-frame Imago system. Both turn immense areas of glass into smooth-moving openings with genuine wood at the heart of the design.
The versatile 78 mm Climatech system is available in all-wood or wood–aluminum-clad construction. Its fixed glass is carried in a four-sided wood panel mounted within the outer door frame.
The 78 mm all-wood Imago system uses thinner wood sections and sets its fixed glass directly into the door frame—creating true ceiling-to-floor glass with even less frame around the view.
Core system 01 · Climatech
Climatech is the adaptable 78 mm Fenstür lift-and-slide platform. It is available in all-wood or wood–aluminum-clad construction, with fixed glass installed in a four-sided wood panel and mounted within the outer door frame.
Core system 02 · Imago
Imago is a 78 mm wood-only system built with thinner timber sections than Climatech. Its fixed glass is set directly into the outer door frame—not into a separate fixed panel—allowing ceiling-to-floor glass and an exceptionally quiet connection to the landscape. It is available only as an OX two-panel system.
Maximum natural-material expression with slimmer timber sections.
Ceiling-to-floor glass without a separate four-sided fixed panel.
The same concealed platform used by Climatech Gen 2, with optional opening and closing dampers.
One fixed and one moving panel, with double- or triple-pane glass.
Imago configurations and concealed-frame details require early coordination with structure, waterproofing, interior finishes and exterior drainage. Final availability depends on the opening and performance requirements.
Installed in real homes
From quiet two-panel openings to complete window walls, these finished Fenstür projects show how a lift-and-slide door can connect the room, the architecture and the view.
Simple technical overview
Fixed glass is installed in a four-sided wood panel that is mounted within the outer frame.
Fixed glass is set directly into the door frame for ceiling-to-floor glass and slimmer timber sightlines.
Both glazing options are available across Fenstür lift-and-slide systems.
One fixed panel and one operable sliding panel.
Subject to glass, roller, track and configuration review.
Final limits depend on panel width, glass weight, exposure and engineering.
Confirm the applicable test report for the quoted assembly.
Climatech Classic uses protruding hardware. Climatech Gen 2 and Imago share the concealed hardware platform, with opening and closing dampers available.
Sizes and ratings depend on product type, operation, glass, exposure and current tested limits. Fenstür confirms the applicable values with the quotation.
The mechanism
A 180-degree handle movement lifts the sliding panel, disengaging the compression seals and transferring its weight to adjustable roller carriages. The panel can then glide rather than drag.
Configurations
Climatech supports common OX and XO two-panel doors, OXXO four-panel assemblies opening from the centre, and other project-specific arrangements that can be reviewed around the architecture. Imago is purposefully focused: it is available only as an OX two-panel system with one fixed panel and one moving panel.
Threshold + sill
Fenstür lift-and-slide doors use the ¾-inch-tall Climatech fiberglass threshold. It forms the track, rolling path and lower sealing interface for the moving panel. Interior flooring can finish neatly against its low profile for a clean, nearly seamless inside-to-outside transition, while the complete sill still coordinates compression seals, drainage, the exterior deck and surrounding waterproofing.
Material + glass
Solid timber brings warmth and scale to the interior. Climatech can be built in all-wood or wood-aluminum-clad construction; Imago is a wood-only system. Every Fenstür lift-and-slide system can be specified with double- or triple-pane glass, while custom finishes and coordinated hardware allow the door to belong to the broader design.
Frequently asked
Climatech is a 78 mm Wood or Alu-Clad system whose fixed glass is installed in a four-sided wood panel mounted within the outer frame. Imago is a 78 mm wood-only system with thinner timber sections and fixed glass set directly into the door frame for ceiling-to-floor glass. Imago uses the same concealed hardware platform as Climatech Gen 2.
Only the hardware system changes. Climatech Classic uses protruding hardware, while Climatech Gen 2 uses concealed hardware. The concealed Gen 2 platform can also be equipped with opening and closing dampers.
Imago is available only as an OX two-panel system with one fixed panel and one operable panel. Climatech supports OX, XO, OXXO and other project-specific arrangements subject to review. All Fenstür lift-and-slide systems are available with double- or triple-pane glass.
A conventional slider typically rolls while remaining in contact with its seals. A lift-and-slide panel mechanically rises from the seals before moving, allowing larger weights and strong compression when closed.
Fenstür uses the low-profile Climatech fiberglass threshold for its lift-and-slide system. The correct installation detail depends on exposure, accessibility, flooring, deck height, pan flashing and drainage, so Fenstür should review it before the surrounding structure is finalized.
