Key Features
Key construction details for insulation, sealing, operation, and North American installation.
Triple Glazing, Sealing & Nail Fin Installation
A 35.3mm thermal break, Low-E double or triple glazing up to 47mm, and three-level sealing work together to improve thermal and weather performance. Nail Fin or mounting tabs are available for common North American wall details.
German G-U Hardware
German G-U hardware is standard for smooth operation and reliable locking in daily use. HK Kinlong hardware is also available as an optional project configuration.
External Drainage Outlet

Performance References
Reference values for project comparison. Final results depend on size, glazing, configuration, and installation.
BTU/(h·ft²·°F) reference. A lower U-Factor indicates less heat transfer through the window system.
Reference air leakage value. The three-level sealing design helps reduce drafts around the operable sash.
Reference value for resistance to rain penetration when the window is closed and properly installed.
Reference resistance for structural loading under wind pressure. Final sizing should be reviewed by project.
Reference sound insulation value. Glass selection and opening size will affect the final acoustic result.
Reference solar heat gain coefficient for the configured glazing system.
