Product Details
The 3040 casement window measures 36 x 48 in (914 x 1219 mm) and belongs to the S9 / WY-127 high-performance outward casement family. It uses a thermal-break 6063-T5 aluminum frame with a 109/118/127 mm depth profile and 2.0 mm wall thickness. A PA66/DERCHI insulation strip separates the frame cavities. Because the 3040 dimension exceeds the ordinary single-sash range, engineering recommends a split-panel layout—combining a fixed transom or lower fixed section with an operable casement sash—rather than forcing a single large sash without hinge and load confirmation.
The primary opening mode is outward opening or awning, which keeps interior space clear while allowing side or bottom ventilation. An E6N inward tilt-turn alternate can be discussed for tall openings. The standard glass package is 5+27A+5 mm double tempered insulated glass with argon gas and a PVDF aluminum spacer. Buyers can configure Low-E, laminated, triple, tinted, frosted, reflective, or bullet-proof glass upgrades to address project-specific thermal, acoustic, or security requirements. Final series, glass package, and hardware must be confirmed at the quote stage.
Product Features
Thermal-Break Aluminum Frame: 6063-T5 aluminum with a PA66/DERCHI insulation strip targets high energy performance by reducing heat transfer across the frame, supporting project thermal requirements.
Argon Insulated Glass: Standard 5+27A+5 mm double tempered glass with argon gas and PVDF spacer offers a baseline for insulation, with upgrade paths to Low-E, triple, and laminated configurations.
WEHAG Hardware System: WEHAG handle and hinge paired with a black two-point or six-point lock provide project-grade security and smooth operation for outward opening sashes.
Split-Panel Engineering: For the 3040 size, a split-panel layout (fixed transom plus operable sash) is recommended to manage sash weight and hinge loads safely without oversized single panels.
Project Color Matching: Multiple color families including Pearl White, Quartz Gray, Starry Sky Black, and wood-grain finishes are available, with PVDF custom color options carrying an upcharge.
Safety and Screen Options: Optional anti-theft screens, 304 stainless steel mesh, diamond mesh, and safety fences allow buyers to configure security and insect protection per project needs.
Customizable Styles
Sash Configuration: Buyers can select single sash, double sash, or side-opening with center fixed layouts depending on structural needs and ventilation preferences for the 914 x 1219 mm casement window.
Split-Panel Layout: Upper or lower fixed sections combined with an operable casement sash are available to manage sash weight and hinge loads for large openings.
Glass Package: Standard argon double tempered glass can be upgraded to Low-E, laminated, triple, tinted, frosted, reflective, or bullet-proof glass per project specifications.
Frame and Color: Thermal-break aluminum frames support powder coating and PVDF finishes, with custom colors and wood-grain options available subject to upcharge thresholds.
Opening Direction: Left or right outward opening configurations are available, and an E6N inward tilt-turn alternate can be discussed for tall openings requiring inward operation.
Hardware Accessories
WEHAG Handle: Available in black or silver finish, providing a branded operating interface that matches project interior hardware themes.
WEHAG Hinge: Sized to sash weight and dimensions, supporting outward opening operation; final hinge specification confirmed during configuration.
Multi-Point Lock: Black two-point or six-point locking system selected by series, offering secure sash engagement for residential and commercial projects.
Casement Limiters: Simple limiters and safety limiters are available as optional upgrades to control opening angle and protect against wind damage.
Screens and Safety Fences: Optional anti-theft, 304 stainless steel mesh, diamond mesh, 48-mesh screens, and fixed/opening safety fences are available for security configurations.
