The 48 x 60 double casement window is a custom thermal-break aluminum configuration built on the DERCHI E6N Xingyue system. Measuring 1219 x 1524 mm, it features two opposing inward-opening sashes that provide balanced ventilation and a symmetrical facade. This is a custom-manufactured window, not a stock product.
- Double-sash layout with each sash measuring approximately 610 mm wide
- E6N system with 103 mm frame width, 2.0 mm wall thickness, and 35 mm PA66 insulation strip
- Inward tilt-and-turn operation for safe, controllable airflow and child safety
- Standard 5+27A+5 fluorocarbon hollow aluminum strip tempered glass
Product Details
The E6N Xingyue system construction centers on a 103mm frame width with a 2.0mm wall thickness, paired with a 35mm PA66 insulation strip. Standard glazing is 5+27A+5 fluorocarbon hollow aluminum strip glass. The double casement structure uses two left-right opposing sashes—each approximately 610mm wide—sharing glass weight through a center mullion for structural stability. Both glass and screen sashes open inward, making the unit suitable for high-rise interior maintenance and safe ventilation scenarios.
For projects requiring different operational logic, alternative series are available. The R8Y Ruixuan system offers outward opening with anti-fall ropes and coastal weather resistance, while the E0 Rongyao series targets budget-conscious batch engineering. Buyers evaluating a custom 48 x 60 double casement window should confirm which system profile aligns with their structural drawings and performance requirements before requesting a quote.
Product Features
- Balanced Dual-Sash Ventilation: Two opposing operable sashes create cross-ventilation and a symmetrical facade aesthetic, distributing glass weight across a center mullion for structural stability.
- Inward Tilt-and-Turn Operation: The E6N system supports inward tilting for controlled airflow and side-swinging for full opening access, addressing child safety and high-rise interior maintenance needs.
- Thermal-Break Construction: A 35mm PA66 insulation strip combined with a Vertical Isotherm Design aims to reduce thermal transfer; buyers should confirm specific U-value ratings for project compliance.
- Triple Sealing System: Features triple sealing with hidden drainage and inner and outer pressure glue strips to manage weather elements; confirm specific water tightness values for exposed installations.
- Structural Corner Integrity: Glue-injected corner codes are used to enhance frame joint strength. The supplier notes a high impact resistance, though test baselines should be verified.
- Flush Surface Aesthetic: Inner and outer flush surfaces provide a modern architectural appearance, accommodating contemporary residential and commercial facade requirements.
Customizable Styles
- Glass: Standard 5+27A+5 tempered glass; custom options include argon gas, Low-E, laminated, frosted, tinted, ultra-clear, and louvered glass for specific privacy or performance needs.
- Frame and Size: Custom sizes are supported. Local opening sash range spans 508-1000mm width and 600-2000mm height; export range spans 510-850mm width and 595-2400mm height.
- Color and Finish: Options include Sand Gray, Dark Coffee, Black Crystal, Starry Black, White, Black Walnut, and Fluorocarbon Flash Silver. Finishes include powder coating, fluorocarbon, and wood grain.
- Opening Configuration: E6N supports inward tilt-and-turn and inward side-swing. R8Y and E0 alternative series offer outward opening and upper tilt modes for different project constraints.
- Structural Combinations: Layouts include fixed plus opening, two-side opening with center fixed, upper transom, lower fixed, asymmetric opening, and multi-pane window wall or bay window combinations.
Hardware Accessories
- Glass Sash Handle: Uses a WEHAG baseless glass sash handle for inward operation. Buyers should confirm handle finish options to match project interior hardware schedules.
- Screen Sash Handle: Features a WEHAG screen sash password handle, adding a layer of access control for interior insect screen operation and child safety.
- Corner Connection: Glue-injected corner codes secure frame joints. The supplier claims high impact resistance, though specific test standards should be verified before ordering.
- Hardware Cycle Life: WEHAG accessories are shown with 100,000+ open cycles. Buyers should request applicable test conditions, load weight, and standard references for project approval.
- Alternative Series Hardware: R8Y outward-opening series includes a 12-inch friction hinge, four-face six-point lock, and anti-fall rope; confirm if similar locking is available for E6N.
