High-rise residential and commercial towers present unique challenges for window specification. At elevated heights, windows must withstand intense wind pressure, driving rain, and temperature extremes while maintaining occupant safety and comfort. Traditional sliding windows often fall short in sealing performance at altitude, and casement windows can pose operational risks on upper floors. Enter the side press window — a hybrid design that merges the space-saving convenience of sliding operation with the airtight performance of casement windows. For developers and architects working on tall buildings, the TS130 Side Press Window from ALPES represents a purpose-built solution tailored to the demands of high-rise life.
A side press window — sometimes called a side-pressure airtight sliding window — combines lateral sliding movement with a compression sealing mechanism. When the sash is closed, precision hardware drives it horizontally toward the frame, squeezing the gaskets on all four sides to create a continuous, airtight seal. The result is a window that slides open like a conventional horizontal sliding window yet seals with the performance level of a casement window.
This dual-mode operation is especially valuable in high-rise settings, where wind loads amplify every gap in the window assembly. Side press technology eliminates the inherent draftiness of standard sliders, making it possible to enjoy the space-saving benefits of sliding designs without sacrificing weather performance.
The TS130 is ALPES's flagship side press window series, engineered from the ground up for demanding vertical environments. Let's examine the core features that make it suited for high-rise installation.
At 130 mm in frame wall width, the TS130 features a substantial aluminum profile constructed from 6060-T66 grade aluminum with a wall thickness of 1.8–2.0 mm — meeting and exceeding China's new national standard for system windows. The 6060-T66 alloy offers an excellent strength-to-weight ratio and exceptional resistance to bending and torsion under wind load, which is critical when windows are exposed to gust forces at 30, 50, or 80 stories above ground.
The defining feature of the TS130 is its side pressure sealing system. A continuous sealing strip runs along all four sides of the sash, and the upper rail frame is further sealed with structural sealant. When the window is locked, German ROTO side-pressure hardware compresses the sash firmly against the frame gasket. This delivers casement-level airtightness and water tightness — a dramatic upgrade over the brush-strip seals found in ordinary sliding windows. For high-rises in coastal or typhoon-prone regions, this level of rain resistance is not a luxury; it is a necessity.
Security at height requires more than a simple latch. The TS130 incorporates an eight-point locking system that distributes clamping force evenly around the sash perimeter. This multi-point engagement not only enhances burglar resistance but also ensures uniform gasket compression, eliminating the weak spots that often develop around single-lock sliding windows. Combined with high-grade stainless steel mesh screens (available in 40# or 80# options), the TS130 provides a layered security envelope suitable for luxury high-rise residences.
Large-format glass panels — increasingly standard in modern high-rise facades — demand robust rolling hardware. The TS130 uses 200 kg load-bearing pulleys designed to handle oversized sashes smoothly and quietly, even after years of daily use. This heavy-duty construction ensures that operation remains effortless on upper floors, where wind suction can add significant resistance to sash movement.
Key Advantages for Tall Buildings
The TS130 supports multiple opening configurations to suit different floor plans and design visions. Options include one fixed + one movable layouts and middle fixed + two sides movable arrangements, giving architects flexibility in balancing daylight, ventilation, and view.
Extended functions further expand the TS130's utility: inward-opening sash mesh, integrated glass railings, anti-theft grilles, and both inward- and outward-opening mesh options are all available. For those planning a sliding window replacement in an existing high-rise, the TS130's adaptable sizing and finish options make it a strong candidate for retrofit projects as well.
Finish-wise, the series is available in standard colors including Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee, with custom color matching available for large-volume projects. This flexibility ensures the windows can harmonize with any facade palette, from ultra-modern glass towers to traditional masonry-clad high-rises.
When specifying windows for a high-rise development, the manufacturer matters as much as the product itself. ALPES operates a 100,000 m² production base across two facilities in Foshan and Zhaoqing, Guangdong, with a track record of supplying premium aluminum windows and doors to luxury villa and high-rise projects across the Middle East, Australia, and beyond. The company manufactures according to international building codes and works with top-tier hardware partners including ROTO, Winkhaus, CMECH, and Wehag — all names trusted in the high-performance fenestration industry.
For developers, contractors, and homeowners seeking a reliable aluminum sliding window supplier for high-rise applications, the TS130 Side Press Window represents a compelling balance of performance, safety, and aesthetic versatility. Its side-pressure sealing technology directly addresses the sealing shortcomings of conventional sliders, while its robust construction and premium hardware ensure long-term durability in the demanding conditions found at altitude.
High-rise windows cannot afford to compromise. Whether navigating intense wind loads, driving rain, noise from urban streets below, or the simple expectation of premium comfort, every component must perform at the highest level. The TS130 Side Press Window rises to that challenge, delivering casement-grade sealing in a sliding format that works beautifully in tall buildings.
