The 36 x 42 casement window is a custom-made thermal-break aluminum unit from DERCHI, built on the E5N Langyue system for inward-opening and tilt-and-turn operation. It is engineered for residential and light commercial projects requiring controllable ventilation and interior-side maintenance.
- Custom thermal-break aluminum frame with 35mm PA66 insulation strip
- Standard 5+27A+5 argon double tempered insulating glass with PVDF spacer
- German WEHAG concealed tilt-and-turn hardware with 90-degree inward opening
- Made-to-order sizing and color configuration for project specifications
Product Details
Structurally, the E5N system features an 85mm frame width, 2.0mm aluminum wall thickness, and a 35mm PA66 insulation strip. Corner joints use glue injection followed by silicone application, combined with a triple seal and concealed drainage to manage weather exposure. The internal and external pressure strip process accommodates 48/88 edge wrapping, while the 90-degree inward opening angle facilitates high-rise interior cleaning.
Standard glazing is 5+27A+5 double tempered insulating glass with argon gas and a black PVDF hollow aluminum spacer carrying the DERCHI logo. The opening sash engineering range is 508-1000mm in width; height ranges differ between the manual (600-2000mm) and the export website (560-2000mm), so buyers should confirm the applicable dimension for their specific configuration. This custom 36 x 42 casement window is built to order, not held as a stock standard product.
Product Features
- Thermal Insulation: The 35mm extra-wide PA66 insulation strip contributes to a 1.8W thermal level. Buyers should request certified U-value test reports to confirm exact ratings.
- Sound Insulation: Rated at 35dB with standard double tempered glass. Confirm specific glass configuration requirements to achieve this acoustic performance.
- Weather Resistance: Triple seal and concealed drainage manage water tightness at 550-700Pa. Confirm which value applies to configurations with or without a flyscreen.
- Controllable Ventilation: Tilt-and-turn operation allows secure micro-ventilation and a full 90-degree inward opening, supporting child-safety and airflow management.
- Interior Maintenance: Inward-opening design enables safe cleaning from inside the room, a practical benefit for high-rise residential or commercial 36 x 42 casement window applications.
- Structural Stability: Glue-injected corner joining followed by silicone application reinforces frame rigidity, while the 2.0mm wall thickness supports wind pressure resistance of approximately 5kPa.
