A custom 4 x 6 casement window from DERCHI uses the E6N Xingyue thermal-break aluminum system to address the engineering challenges of a 48 x 72 in (1219 x 1829mm) opening. It is built to order for project residential and high-rise applications.
- Overall height of 1829mm requires inward-opening or segmented structures to avoid exceeding outward sash limits
- Features a 103mm frame, 2.0mm wall thickness, and 35mm PA66 insulation strip
- Standard glazing is 5+27A+5 fluorocarbon hollow aluminum bar insulating glass
Product Details
The E6N Xingyue system forms the core of this custom 4 x 6 casement window, utilizing a 103mm frame width and 2.0mm wall thickness. Because the 1829mm overall height exceeds conventional limits for outward-opening sashes, the recommended configuration uses an inward-opening high window or a top/bottom fixed plus middle opening structure. In a double-sash layout, each sash measures approximately 610mm wide; in a three-lite layout, each lite is about 406mm wide.
Standard glass is 5+27A+5 insulating tempered glass with a fluorocarbon hollow aluminum bar. The system applies inner and outer pressure glue strips, three-way sealing, hidden drainage, and glue-injected corner codes. For projects requiring different parameters, the E5N series (85mm frame, narrow high windows) and R8Y series (118mm frame, coastal outward-opening) offer alternative configurations. Buyers should confirm exact performance ratings for the E6N series directly, as values from E5N or R8Y do not automatically apply.
Product Features
- Vertical Isotherm Design: The 35mm PA66 insulation strip and 7-level thermal insulation work together to reduce heat transfer, supporting energy efficiency in project residential builds.
- Glue-Injected Corner Code: Corner joints use an injected adhesive process rated at 10 times the impact strength of normal screws, keeping the frame rigid under structural stress.
- Three-Way Sealing: Inner and outer pressure glue strips combined with hidden drainage channel help manage water intrusion and air leakage at the frame perimeter.
- WEHAG Hardware: German WEHAG accessories carry a 100,000+ open-cycle rating, providing high load-bearing support for daily operation of large sashes.
- Inward Tilt-Turn Modes: The system allows inward-opening tilt-turn and inward side-hung operation, giving occupants controllable ventilation and easy indoor cleaning access.
- Child Safety Configuration: With the screen sash opening inward and the glass sash opening inward, the setup prioritizes child safety and secure ventilation on upper floors.
Customizable Styles
- Glass: Standard 5+27A+5 insulating tempered glass; custom options include argon gas, Low-E, laminated, frosted, tinted, ultra-clear, and louvered glass for privacy or coastal exposure.
- Frame and Size: E6N opening sash ranges from 508-1000mm wide and 600-2000mm high locally; export dimensions and fixed glass maximums should be confirmed with the supplier.
- Colors and Finishes: Options include Sand Gray, Dark Coffee, Black Crystal, Starry Black, White, Black Walnut, Pear Wood, Fluorocarbon Flash Silver, and Indigo Gray across powder coating, fluorocarbon, and wood grain finishes.
- Opening Configuration: Choose inward tilt-turn or inward side-hung; if outward opening is required, use a top transom or bottom fixed glass to keep the opening sash within conventional limits.
- Project Structures: Layouts include single sash, double internal opening, fixed plus opening, three-segment, left-right asymmetric, multi-lite window walls, and slanted or bay window combinations.
Hardware Accessories
- Glass Sash Handle: The E6N glass sash uses a WEHAG baseless handle, providing clean visual lines and reliable operation for inward-opening configurations.
- Screen Sash Handle: A password handle secures the inward-opening screen sash, adding an access control layer for child safety and high-rise ventilation.
- Corner Hardware: Glue-injected corner codes replace standard screws, delivering structural rigidity rated at 10 times the impact strength of conventional fastening.
- Load-Bearing System: WEHAG Germany accessories carry a 100,000+ open-cycle rating, supporting the weight of 5+27A+5 double tempered glass units.
- R8Y Alternative Hardware: For outward-opening scenarios, the R8Y series uses a 12-inch friction hinge and a custom black zinc alloy four-side six-point lock; buyers should verify which hardware applies to their order.

FAQ
Can this 4 x 6 casement window open outward?
The 1829mm overall height exceeds conventional limits for outward-opening sashes. The recommended structure is inward-opening or top/bottom fixed plus middle opening. If outward opening is required, the R8Y series offers an alternative configuration.
What information is needed for a quote?
Buyers should provide project drawings, opening dimensions, quantity, preferred glass configuration, color finish, and delivery destination. A 4 x 6 casement window supplier can then calculate exact pricing based on the E6N system specifications.
What glass options are available?
Standard glass is 5+27A+5 insulating tempered glass with a fluorocarbon hollow aluminum bar. Custom options include argon gas, Low-E, laminated, frosted, tinted, ultra-clear, and louvered glass. Confirm specific argon fill percentages and Low-E specs with the supplier.
Are test reports and certifications available?
Buyers should request specific certification listings like NFRC, AAMA, or CE for their target market. Request water tightness, air tightness, sound insulation, and wind pressure test reports specific to the E6N configuration, as E5N or R8Y values do not automatically apply.
What is the delivery time and packaging?
Platform data indicates approximately 25-35 days delivery, though this may vary by actual order. Export packaging uses four-layer protection: anti-scratch film, pearl cotton, waterproof outer film, and a fully enclosed wooden rack. Door-to-door or port shipping is available.
What should buyers confirm before ordering?
Confirm exact warranty terms, U-value/SHGC ratings, maximum glass weight capacity for the WEHAG hardware, and installation details. Also verify whether grilles, divided-lite patterns, or integrated shading options are available for the project.
