For project buyers, a good uPVC casement window is not only about the frame. It also depends on profile strength, sash size, glass weight, steel reinforcement, sealing system, hardware quality and installation conditions.

uPVC casement windows can be designed as inward opening or outward opening.
Inward opening uPVC casement windows are easy to clean and adjust from inside the room. They are commonly used in apartments, villas and residential projects.
Outward opening uPVC casement windows help save indoor space and are suitable for projects where interior layout is limited.
The final choice depends on building design, room function, local climate, safety needs and installation conditions.
Flush uPVC casement windows are designed so that the sash sits more level with the outer frame, creating a cleaner and more modern appearance.
They are commonly used in modern villas, apartments and premium residential projects. Flush casement designs can be combined with double glazing, Low-E glass, black profiles, grey profiles, wood grain finish and multi-point locking hardware.
For flush casement windows, profile compatibility, sash size, gasket compression and hardware selection should be checked before production.
White is the most common color for uPVC casement windows, but many projects also require black, grey, brown or wood grain finishes.
Available color options include:
White uPVC casement windows
Black uPVC casement windows
Grey uPVC casement windows
Brown uPVC casement windows
Wood grain uPVC casement windows
Laminated color profiles
For black or dark-color uPVC casement windows, we recommend checking window size, local temperature, solar exposure, steel reinforcement and installation gap before production.
Double glazed uPVC casement windows are a common choice for energy-saving and sound reduction projects.
A typical glass configuration is:
5 + 12A + 5 mm insulated glass
Optional upgrades include:
Low-E glass
Argon-filled insulated glass
Laminated glass
Tempered glass
Triple glazing
Warm edge spacer
For hot climates, Low-E double glazing is often recommended to reduce solar heat gain and improve indoor comfort. For noisy areas, laminated glass or thicker insulated glass can improve sound insulation.
We support custom uPVC casement window sizes based on project drawings, wall openings and window schedules.
When confirming sizes, we check:
Sash width and height
Glass weight
Opening direction
Wind pressure
Hardware load
Steel reinforcement
Installation gap
Mullion and transom design
Large casement sashes should be reviewed carefully to avoid sash sagging, difficult operation or hardware overload.
Hardware affects the daily operation and lifespan of uPVC casement windows.
Our hardware options can include:
Window handles
Adjustable hinges
Multi-point locking system
Locking points
Hardware load
Safety restrictors
Corrosion-resistant hardware
Upgraded hinges for large sashes
For large windows, high-frequency use or coastal projects, upgraded hardware is recommended. A proper handle, hinge and locking system can improve sealing pressure, security and long-term operation.
A good uPVC casement window should not only close smoothly but also seal properly.
Our window design can include:
EPDM gasket
Triple sealing option
Precision welded corners
Proper sash-frame overlap
Drainage channels
Weep holes
Multi-point locking compression
Good sealing helps reduce air leakage, dust entry, water leakage and outdoor noise. Drainage holes should not be blocked during installation.
The price of uPVC casement windows depends on the final configuration.
