The 36 inch casement window from DERCHI is a made-to-size thermal-break aluminum system window organized by width segment — not a stock standard product. The primary E6N series features inward-opening operation, with S9 and R8Y outward-opening series available for projects requiring different ventilation, safety, or climate responses.
- 36 inches (≈914mm) falls within the E6N sash opening width range — buyers should confirm whether this refers to rough opening, sash size, or nominal width
- Three system series cover inward-opening, high-end outward, and safety/coastal outward project requirements
- Custom glass, color, structure, hardware, and screen options support project-specific configuration
Product Details
The primary recommended series for this custom 36 inch casement window features a 103mm frame width, 2.0mm wall thickness, and 35mm PA66 insulation strip paired with 5+27A+5 fluorocarbon hollow aluminum spacer glass. Construction includes inner and outer pressure glue strip process, triple seal, inner/outer flush surfaces, hidden drainage, glue-injected corner code, and Vertical Isotherm Design. The glass sash and screen sash both open inward, supporting tilt-and-turn and side-hung modes for controllable ventilation and interior maintenance access.
For projects requiring outward opening, the S9 Xingguang system (109mm frame, 1.8mm wall, 44/24/15mm multi insulation strip) and R8Y Ruixuan system (118mm frame, 1.8mm wall, 35/34/16mm insulation strip, EPDM water-swellable glue strip) offer alternative configurations. E6N size ranges differ between the local manual (sash width 508–1000mm, height 600–2000mm, max fixed glass 12 sqm) and the export website (width 510–850mm, height 595–2400mm, fixed glass ≤6 sqm) — buyers should confirm which standard applies to their project before finalizing dimensions.
Product Features
- Thermal Performance: Triple seal with 35mm PA66 insulation strip and Vertical Isotherm Design reduce thermal bridging. The claimed "7 levels thermal insulation" requires verification of the exact standard before code compliance reliance.
- Structural Integrity: Glue-injected corner code, inner/outer flush design, and hidden drainage contribute to frame rigidity and weather management. The "Super impact" comparison requires test standard confirmation before specification.
- Hardware Durability: WEHAG Germany accessories support the E6N sash with a 100,000+ open-cycle reference. Buyers should confirm the test standard behind this cycle figure for project documentation.
- Opening Flexibility: E6N offers inward tilt-and-turn plus inward side-hung modes, while S9 and R8Y provide outward side-hung and top-hung options — matching different ventilation, cleaning, and space constraints.
- Safety and Usability: Inward opening suits high-rise interior maintenance and child safety scenarios. Controllable tilt-and-turn ventilation supports quiet indoor environments without fully opening the sash.
- Export Packaging: Four-layer protection includes anti-scratch film, wear-resistant pearl cotton, waterproof outer film, and fully enclosed wooden rack — configured for overseas shipping handling and long-distance transport.
Customizable Styles
- Glass: Standard 5+27A+5 hollow tempered glass; custom options include argon, Low-E, laminated, frosted, tinted, ultra-clear, and blind glass — confirm thickness and coating for project needs.
- Color and Finish: Twelve verified E6N colors include Sand Gray, Dark Coffee, Black Crystal, White, and more. Finishes span powder coating, fluorocarbon, wood grain, and metal flash silver.
- Size: E6N sash width ranges from 508–1000mm (local manual) or 510–850mm (export). Buyers must confirm required height and whether 36 inches refers to rough opening or sash size.
- Structure: Options range from single sash to multi-pane window wall, including fixed+opening, three-segment, top light, asymmetric, hexagonal, and bay-style combinations — provide drawings for complex layouts.
- Screen and Blinds: E6N includes a screen sash with password handle; S9 offers optional 48-mesh screen, steel wire mesh, and blinds. Blind glass is available as a custom glass option.
Hardware Accessories
- E6N Glass Sash Handle: WEHAG baseless handle operates the inward-opening glass sash. Buyers should confirm sash weight requirements for proper hardware selection.
- E6N Screen Sash Handle: WEHAG password handle controls the inward-opening screen sash, adding a security layer for child safety and controlled access scenarios.
- S9 Hardware Set: German-tech custom child handle, 13-inch friction hinge, and custom lock point with strike — optional fingerprint, password, or key handle upgrades available.
- R8Y Hardware Set: WEHAG baseless handle, 12-inch friction hinge, and custom black zinc alloy four-face six-point lock for multi-point locking security.
- Structural and Sealing Hardware: Glue-injected corner code reinforces frame joints; EPDM water-swellable glue strip (R8Y) and hidden drainage support weather resistance — confirm performance test standards.
