Six sliding systems, from slim-framed to almost frameless
Two slim-framed aluminium doors on a 55 mm sight line, a wood/aluminium lift-and-slide built for large glass fronts, and three cero systems in which the frame is measured in millimetres. Filter by material, then open any system for its published figures.
The slim all-rounderEcoline S
A thermally broken aluminium sliding door with an unbroken, uniform sight line and just 55 mm of profile visible in the panel butt joint. Panels to 2700 × 2500 mm, an accessible floor track with cascading drainage, and the cero running gear.
55 mm sight line · panels to 2700 × 2500 mm · accessible threshold
The wide-panel partnerHighline S
The same slim 55 mm sight line with panels up to 3200 × 2800 mm, so a wide opening needs fewer leaves and more of the elevation is glass. Glass levels sit flush with adjoining windows and bi-folding doors.
Panels to 3200 × 2800 mm · 55 mm sight line · double glazing
The wood-aluminium lift-and-slideSL 179
A two-track lift-and-slide system in wood/aluminium, with laminated engineered timber profiles, an accessible floor threshold and bottom-running lift-and-slide technology for large glass fronts.
Uw ≥ 0.7 W/m²K · sound to 45 dB · water tightness 9A
The most minimal of allcero IV
Structural glazing minimalism: 2 mm of profile visible vertically and 15 mm horizontally, triple glazing and panels up to 12 m² and 1,000 kg. Winner of an Excellent Product Design award from the German Design Council.

Sliding Doors Design and Budget Guide
Minimal frame aluminium sliding doors: planning the opening, comparing layouts, reading a specification, choosing glass, thresholds and drainage, and budgeting the whole package, with a project checklist for your enquiry.
Download · PDF · 4.3 MBcero brochure
Slim profiled cero sliding doors open up rooms with impressive, extensive glass panels, from cero I-s through cero II and cero III to cero IV.
Download · PDF · 8.3 MBWide openings, one moving leaf, no stacking space needed
A sliding door takes the panel across the wall instead of folding it into the room, so the opening stays clear and the furniture stays where you put it. Here is what the range does at the detail level.
The opening stays clear
Panels run along the wall instead of stacking in front of it, so there is no bundle of leaves to walk around and the room keeps its full depth. Moving up the range buys larger panels, so a wide opening needs fewer of them.
Sight lines down to 2 mm
The Ecoline S and Highline S show 55 mm of profile at the panel butt joint, the cero III and cero II show 34 mm, and the cero IV takes it to 2 mm vertically and 15 mm horizontally, so on the largest elevations the frame almost disappears.
Thermal and weather performance
The wood/aluminium SL 179 lift-and-slide reaches Uw values from 0.7 W/m²K, and the cero systems follow closely on triple glazing. Water tightness runs to class 9A and resistance to class C5, with the specification matched to the exposure of your site.
Security, tested and certified
The cero III is PAS 24:2016 certified and accredited under Secured by Design, with RC 3 burglar resistance, and the SL 179 is available to RC 2/RC 2N. Motorised locking and unlocking can be specified on the cero systems.
From a terrace threshold to a whole facade of glass
Terraces and gardens
The Ecoline S and Highline S open a kitchen or living space onto a terrace across an accessible floor track with built-in cascading drainage, on no more than 55 mm of profile at the panel joint.
Living spaces and wintergardens
The SL 179 and the cero systems are used where the glass front is the architecture: large panels, glass levels flush with adjoining windows and bi-folding doors, and finishes from 30 RAL colours to warm timber.
Panoramic facades
The cero IV carries panels up to 12 m² and 1,000 kg with a structural-glazing appearance, so an entire elevation can be one unbroken view of the landscape.
Pools, accessible homes and renovation
In pool halls and accessible homes the flush floor tracks of the cero II and cero III give step-free access, and the systems are specified for the humidity, the exposure and the existing opening.
Sliding doors in the openings they were specified for
Terraces, kitchen and dining spaces, garden rooms and whole facades in glass, from a slim 55 mm sight line to the near-frameless cero systems.
