OS-Triple [56mm] Minimalist Sliding System
Overview
Specially conceived for larger frames, the OS minimalist sliding system rose as an answer to the most contemporary architectural trends, aiming to combine the maximum transparency with the minimum structural view, in all its sill versions: Traditional, Concealed with aluminium cover and Concealed with continuous flooring. Combined with the motorized opening system, the OS System allows the design of frames of large dimensions, allowing as such an extra area of glazing. To the three strands of our minimalist sliding OS system — OS-Simple, Double and Triple — we now add the version OS-Concealed Sill.
OS minimalist sliding system with thermal break. Also referenced as "Sistema OS Triple" or "Sistema OS-T [56mm]".

Product highlights in detail
Configuration & planning
14.00 m², 1000 kg (motorised) and 6000 mm per sash; 23 mm or 56 mm tempered filling.
System integration
Triple-glazing capable for higher thermal and acoustic performance, motorised heavy-sash operation, and powder-coated, anodised or bicolour finishes.
Key system data
- Aluminium: 56 mm
- Triple Glazing: 56 mm
- Sightline: 20 mm
- Max Weight: 1000 kg
- Max Height: 6000 mm
- Motorised
Sightline is the 20 mm central sight; the lateral sight is 30 mm and the upper/lower sights are 6 mm. The 1000 kg maximum weight per sash is reached with motorisation. Filling is available at 23 mm or 56 mm; 56 mm supports triple glazing. Full figures are tabled under Technical information.
01 — Planning benefit
Planning benefit
OS-Triple is the largest-section member of the OS minimalist sliding family, using a 56 mm filling/profile depth (with a 20 mm central sightline) and supporting triple glazing, for projects that need extra thermal and acoustic performance combined with maximum transparency. As with OS-Simple and OS-D+, it can be executed with a traditional sill, a concealed sill with aluminium cover, or a concealed sill with continuous flooring for a level indoor–outdoor threshold.
System & opening types
- Filling/profile depth: 56 mm (also available as 23 mm)
- Central sightline: 20 mm · Lateral sightline: 30 mm · Upper/lower sights: 6 mm
- Sill options: Traditional / Concealed with aluminium cover / Concealed with continuous flooring
- Operation: Manual (standard) or Motorised (optional — required to reach the maximum 1000 kg/sash rating)
- Rail configurations: 1-Rail, 2-Rail, 3-Rail and 4-Rail multi-sash layouts, plus a 90° corner junction configuration
Configuration & planning
- Maximum area/sash: 14.00 m²
- Maximum weight/sash (with motorisation): 1000 kg
- Maximum height/sash: 6000 mm
- Filling (tempered glass): 23 mm or 56 mm
- For other dimensions, contact our Technical Department
System integration
- Triple-glazing capable, for enhanced thermal and acoustic performance versus OS-Simple/OS-D+
- Motorised opening compatible with large-format, heavy sashes (up to 1000 kg)
- Finish options: Powder coated / Anodised / Bicolour
02 — System integration
System integration
Triple glazing capability — 23 mm or 56 mm filling depth, with 56 mm supporting triple-glazed tempered units — the defining feature versus OS-Simple/OS-D+.
Motorised operation for heavy sashes — Motorisation is required to reach the system's maximum 1000 kg/sash rating.
Concealed sill / continuous flooring — Traditional, concealed with aluminium cover, or concealed with continuous flooring for a level, barrier-free indoor–outdoor transition.
Profile cross-section & rail configurations — 56 mm filling/profile depth (vs. 32 mm for OS-Simple/OS-D+), with a 20 mm central sightline; available in 1-Rail, 2-Rail, 3-Rail and 4-Rail multi-sash layouts plus a 90° corner junction configuration.
Shared finish & quality scheme — Powder coated / Anodised / Bicolour finishes, plus the group-level Qualicoat Seaside / Qualanod certified finish range.
Related OS-family systems — OS-Simple (single track, 32 mm) and OS-D+/OS-Double (double track, 32 mm) are the smaller-section members of the same family.
