This Suspended Top-Track “Accordion” Glass Curtain System offers a premium solution for spaces where openness, transparency and flexibility are key. The design uses a high-quality support rail mounted at the top, meaning that the panel leaves operate without a visible bottom profile or sill. This architecture allows for a completely unobstructed floor surface and an uninterrupted continuous view, ideal for commercial fronts, modern offices, hospitality venues, and high-end residential panoramas.
The system is built to handle large glazed leaves: individual panels of modest widths and heights (up to approximately 1000 × 3000 mm) and weights up to 150 kg.
Such load capacity is enabled by heavy-duty roller carriages (e.g., Quattro HD) that ensure smooth gliding even with substantial glass panels. The panels may pivot on one edge and fold neatly when opened, enabling configurations of 2, 3, 4, 5, 6 or even 7 folding leaves per opening.
From an aesthetic standpoint, the frameless glass curtain look creates a modern, minimalistic and open façade. With no visible lower rail interrupting the floor plane, this system delivers a flush threshold or completely threshold-free transition, which is particularly appealing in hospitality, retail, and high-footfall public settings. The “curtain” effect of the glass also enhances natural daylight penetration and sight-lines, whilst maintaining structural elegance.
On the technical side, comfort and durability are central. Side profiles feature EPDM polymer gaskets, and both top and bottom of each panel include brush seals to protect against wind infiltration, dust ingress and acoustic transmission improving the internal environment and reducing maintenance overheads. The mechanical components like hinges, carriages, anti-back-drive fixings, are engineered for reliable, quiet, effortless operation.
In practical terms, the system is highly versatile. You can specify it for large commercial façades, such as retail showrooms where you want to merge indoor and outdoor spaces, or for premium residential terraces facing panoramic views. The ability to fold panels fully aside gives you flexibility: the façade becomes an open void or closes into a sealed glass wall depending on your needs for weather protection, acoustics or security.
Maintenance is simplified: the suspended track means no bottom sill to collect water, dirt or debris, and the high-quality rollers ensure long service life with minimal adjustment. The zero-threshold floor transition means no trip hazard and improved accessibility for wheelchairs or trolleys, making it suitable for public venues, hospitals, educational or sports centres.
From a sales and marketing perspective, the key selling points to emphasise are its ability to create “wow” visual impact, improve user experience through seamless transitions, and deliver performance in terms of durability, acoustics and ease of use. Because the system supports large glazed panels and heavyweight operation, it appeals to clients who want premium, high-end architectural solutions rather than standard sliding or hinged doors.
Installation considerations include structural support for the top track (must handle cumulative panel weight), proper alignment for smooth operation, and specification of the correct sealing and glass type (tempered or laminated) given the hardware load rating. The product’s flexibility in folding configurations means you can tailor the system to suit the specific opening width and traffic pattern of each project. It is especially suited to wide spans where traditional hinged or sliding solutions would limit visual openness or require centre posts.
This Suspended Top-Track “Accordion” Glass Curtain System offers a sophisticated, high-performance solution for designers, architects and decision makers looking to maximise daylight, views and seamless indoor-outdoor integration, without compromising on ease of use, durability or interior comfort. It stands out as a premium product in your catalogue for clients who expect top quality and visual impact.
