A custom 6 pane casement window from DERCHI uses a thermal-break aluminum frame to combine traditional divided lite aesthetics with modern energy performance. It is built to order, not stocked, and each lite can be independently configured.
- Available in three series: S9 (high-end), S6 (project), and E0 (budget)
- Each lite can be fixed, openable, an inward screen, or a safety grille
- Standard 5+27A+5 double tempered glass with fluorocarbon aluminum spacer
- Outward opening glass sash with inward or hidden folding screen options
Product Details
The 6 pane casement window is a divided lite style, not six independent products. Buyers can select a 3-column by 2-row grid or a three-sash lower opening with an upper fixed transom. Each lite functions independently as fixed glazing, an openable ventilation sash, an inward screen sash, or a safety guard grille. The glass sash opens outward, while the screen sash opens inward on the S9 and E0 series, or operates as a hidden folding type on the S6 series.
Three thermal-break aluminum series accommodate different project tiers. The S9 features a 109mm frame with a 44/24/15mm insulation strip configuration, the S6 uses an 82mm frame with a hidden folding screen, and the E0 offers a 100mm value-type frame. All share a 1.8mm multi-cavity profile, a three-seal structure, a micro-elastic glass block to reduce corner stress, and EPDM water-swelling weather strips. As a 6 pane casement window manufacturer, DERCHI allows buyers to match structural specifications to project budget and performance requirements.
Product Features
- Verified Performance Ratings: All series share water tightness 700Pa Class 6, air tightness 1.2 Class 8, sound insulation 35dB Class 4, and wind pressure resistance 5kPa Class 9. Buyers should confirm testing standards apply to their configuration.
- Multi-Cavity Thermal Break: The 1.8mm wall thickness multi-cavity aluminum profile combined with a 44mm ultra-wide insulation strip on the S9 helps reduce heat transfer and supports lower U-values for energy-efficient buildings.
- Independent Lite Configuration: The divided lite design allows each of the six panes to be customized independently as fixed, openable, screen, or safety grille, giving architects flexibility in ventilation and daylighting planning.
- Comprehensive Safety Hardware: S9 includes a custom child-safe handle, anti-pull oblique transmission box, two-point lock, roller-sleeve lock point, and anti-pry lock keeper to address residential security concerns.
- Stress-Reducing Glass Block: A micro-elastic glass block system reduces glass corner stress, while the frame and sash sit on the same horizontal line for a clean, modern exterior appearance.
- EPDM Weather Sealing: EPDM water-swelling weather strips expand upon contact with moisture, helping to maintain seal integrity during heavy rain and supporting the verified water tightness rating.
Customizable Styles
- Glass Options: Standard 5+27A+5 double tempered glass; argon gas, Low-E, laminated, frosted, tinted, ultra-clear, and blinds glass available for specific light control and energy needs.

Hardware Accessories
- Handle Options: S9 includes a custom child-safe handle; S6 uses a WEHAG handle without base plate. Optional fingerprint, password, and key handles are available for enhanced access control.
- Friction Stay Hinge: The S9 features a 13-inch friction stay hinge and custom load-bearing hinge to manage outward sash weight and maintain stable opening angles.
- Locking System: S9 includes an anti-pull oblique transmission box, two-point lock, roller-sleeve lock point, and anti-pry lock keeper for multi-point security.
- Screen and Mesh: Options include a 48-mesh high-transparency screen, steel wire mesh for security, and a hidden folding screen on the S6 series to keep interiors clean.
- Safety Accessories: Optional guardrails and safety screens are available. Buyers should confirm hardware brand details beyond WEHAG with the sales team before ordering.
