Zhi Shang inward-opening and shutting window, 70x32mm frame, easy to clean from inside. CMECH hardware and full weather sealing.
The Zhi Shang Inward-Opening Aluminum Window is designed for projects where the window needs to open into the room rather than outward. This configuration is especially useful in apartments, high-rise buildings, balconies, narrow courtyards, and other locations where external clearance is limited.
The system uses a compact 70 × 32 mm aluminum frame and 5 + 20A + 5 double-tempered clear glass. It is fitted with CMECH America hardware and features inward opening and closing with an arch-bent frame design.
The frame is a compact 70 x 32mm, built with the same argon-filled double glazing and CMECH America hardware as the rest of the casement range, and finished in the same Bilbao Black or Flash Silver Gray options.
The main advantage of Zhi Shang is its inward-opening configuration.
Because the sash opens toward the interior, the external side of the window remains clear. This can be useful when outward-opening windows would interfere with:
The inward-opening design also makes the outside glass easier to reach from inside, which can be an important consideration for upper-floor apartments and other difficult-to-access elevations.

The Zhi Shang uses a 70 × 32 mm frame, providing a relatively compact profile for projects where the window needs to fit within controlled architectural openings.
Its 2.2 mm section thickness gives the system a defined aluminum profile suitable for residential and architectural applications.
The specified glazing is:
5 mm + 20A + 5 mm double-tempered clear glass
The double-glazed configuration provides two glass panes separated by a 20A cavity. This makes the system suitable for projects where insulated glazing is required as part of the window specification.
Actual thermal, acoustic, and weather performance depends on the complete window assembly and installation.
Zhi Shang uses CMECH America hardware as standard.
The hardware supports the window’s opening, closing, and locking functions and should be coordinated with the final project configuration.
The product includes arch bending as part of its frame construction.
This gives the window a smoother architectural appearance and can be used where a refined frame profile is preferred over conventional sharp corner detailing.
Zhi Shang is particularly suitable for:
The inward-opening design allows the exterior glass surface to be accessed from indoors, which is useful for upper-floor windows where external cleaning and access can be difficult.
Because the sash does not project outward, it can reduce interference with balcony space and external circulation.
Suitable for bedrooms, living areas, kitchens, studies, and other rooms where an inward-opening window is preferred.
Useful where there is limited clearance between opposing walls or other external structures.
A practical option for buildings where external façade space is restricted.
Can be considered where existing openings or surrounding structures make outward-opening windows impractical.
Zhi Shang can be specified by:
The inward-opening configuration is particularly relevant to UAE and GCC apartment and high-rise projects, where balconies, compact façades, external shading, and limited access can influence window selection.
For these projects, the design team should assess:
YSUN specifically positions the product around GCC apartment and high-rise use cases.
Before ordering, project teams should confirm:
Because the sash opens inward, sufficient room should be available inside for the sash, handle, and hardware movement.
