Multi-cavity bridge cut aluminum profiles effectively block thermal conduction. The multi-channel sealing design prevents sound leakage, ensuring a quiet and energy-efficient environment.
Utilizing a 45° diagonal joint with corner code injection glue. This ensures ultra-high structural strength, ultimate sealing performance, and long-lasting durability against wind pressure.



Equipped with a complete set of HOPO hardware made of high-strength alloys. Includes specialized window corner protectors to avoid harm to children.
Hidden drainage holes effectively discharge rainwater while improving airtightness. Includes windproof covers to prevent dust and insects from entering the profile cavity.
