DERCHI offers a multi-series thermal-break aluminum casement window system organized for new construction project selection. The S9 Starlight Series serves as the primary recommendation, while the R8Y Ruixuan Series targets safety and coastal scenarios, and the E6N Xingyue Series handles inward-opening project residential applications.
- Three distinct series covering high-end, safety-focused, and inward-tilt project requirements
- Verified performance ratings including 5kPa wind pressure resistance and 700Pa water tightness
- Extensive structural combinations from single sash to multi-grid window walls
- Custom glass, color, finish, and hardware configurations available for project buyers
Product Details
The system differentiates itself through a three-series architecture tailored to specific building and environmental conditions. The S9 uses a 109mm frame with a 44/24/15mm multi-insulation strip configuration and a micro-elastic glass block to reduce corner stress. The R8Y features a 118mm frame with equal-pressure and concealed drainage for demanding weather scenarios. The E6N offers a 103mm, 2.0mm wall thickness inward-tilt-and-turn system with a Vertical Isotherm Design and glue-in corner connector for enhanced structural integrity.
Each series employs a three-seal structure and EPDM water-swelling seal strips, while sharing a standard 5+27A+5 fluorocarbon insulated aluminum spacer glass. The S9 supports opening sash widths of 400-750mm and heights of 400-1500mm, with a maximum single fixed glass area of 6 square meters. This approach allows builders to match exact window schedule requirements across different facade zones without switching suppliers.
Product Features
- Multi-Cavity Thermal Break: The S9 uses a 44mm ultra-wide insulation strip and multi-cavity aluminum profile to help lower U-value and improve thermal and acoustic insulation for energy-efficient building envelopes.
- Three-Seal Weather Protection: All series feature a three-seal structure paired with EPDM water-swelling strips, enhancing air and water tightness against wind-driven rain and temperature fluctuations.
- Equal-Pressure Drainage: The R8Y incorporates equal-pressure and concealed drainage channels, directing water outward efficiently while maintaining a clean exterior frame appearance.
- Vertical Isotherm Design: The E6N utilizes a Vertical Isotherm Design and internal/external flush surfaces to minimize thermal bridging and support consistent interior climate control.
- Glass Sash Separation: Outward-opening series separate the glass sash from the inward-opening screen sash, allowing independent operation for ventilation while keeping the screen inside.
- Structural Corner Reinforcement: The E6N uses a glue-in corner connector designed to be significantly stronger than standard screws, improving frame corner rigidity and long-term impact resistance.
Customizable Styles
- Glass Options: Standard 5+27A+5 double tempered glass; optional upgrades include argon gas, Low-E, laminated, frosted, tinted, ultra-clear, and blind glass configurations.
- Frame and Size: S9 opening sash ranges from 400x400mm to 750x1500mm; custom dimensions and structural combinations like fixed+opening or multi-grid walls are available per project drawings.
- Colors: Twelve verified colors including Sand Gray, Black Crystal, White, and Fluorocarbon Flash Silver; additional E5N color card options may be available subject to series confirmation.
- Surface Finishes: Powder coating, fluorocarbon, wood grain, and metallic flash silver finishes available to match diverse facade and interior design requirements.
- Opening Configurations: S9 and R8Y support outward, top-hung, and outward-top-hung modes; E6N supports inward-tilt-and-turn and inward casement opening for varied ventilation needs.
Hardware Accessories
- S9 Handles and Hinges: Features a custom child-safe handle and a 13-inch friction hinge, with an optional upgrade to a fingerprint, password, or key handle for added security.
- R8Y Locking System: Equipped with a WEHAG baseless handle, a 12-inch friction hinge, and a custom black zinc alloy four-face six-point lock for robust anti-theft protection.
- E6N Inward Hardware: Includes a WEHAG baseless glass-sash handle and a screen-sash password handle, supporting secure inward-tilt-and-turn operation.
- Shared Lock Points: Across configurations, hardware options include anti-pull angled transmission boxes, two-point locks, roller-sleeve lock points, and anti-pry strike plates.
- Screens and Guardrails: Optional 48-mesh high-transparency screens, steel wire mesh, guardrails, and blinds are available; confirm specific compatibility with the selected series.
