- Custom built to 36 x 36 in (914 x 914 mm), not a stock standard window
- E5N system with 85 mm frame, 2.0 mm wall thickness, and 35 mm insulation strip
- Standard 5+27A+5 argon double tempered glass with PVDF spacer
- German WEHAG/Winkhaus concealed tilt-and-turn hardware
Product Details
The E5N Langyue system construction features an 85 mm frame width, 2.0 mm aluminum wall thickness, and a 35 mm PA66 insulation strip. The frame-sash is flush with clean proportions, supporting single-sash inward opening or double narrow-sash configurations. Corner joints are glue-injected followed by silicone application, and the system uses internal and external pressure rubber strips with a triple seal and concealed drainage.
Standard glass is 5+27A+5 double tempered insulating glass with argon gas and a black PVDF hollow aluminum spacer bearing the DERCHI logo. Buyers can configure 48/88 edge wrapping. The inward opening system allows interior cleaning access, making it practical for high-rise applications. As a custom 36 x 36 casement window, exact dimensions and tolerances beyond the nominal 914 x 914 mm should be confirmed with project drawings.
