Product Highlights
Thermal and Sound Insulation
Multi-cavity structure profiles (thermal break aluminum) effectively block thermal conduction.
Multi-channel sealing design (triple seal) fills gaps between sash and frame to prevent sound leakage.
Advanced Splicing & Safety
45° diagonal joint with corner code injection glue ensures high structural strength and wind pressure resistance.
Ultimate sealing performance blocks air and moisture from the corners.
Integrated corner protectors effectively avoid harm, especially for children.
Concealed Drainage System
Efficiently discharges rainwater outward and reduces backflow risk during storms.
Enhanced air tightness helps isolate external noise and maintain indoor temperature.
Invisible drainage covers prevent insects and dust from entering the profile cavity.

Frequently Asked Questions
1. Can colors and sizes be customized?
Yes. In addition to conventional electrostatic powder coating, we provide high-end surface treatments like imitation wood grain transfer printing. All sizes are customized to your specific requirements.
2. How is the product price calculated?
Pricing depends on the configuration, including profile series, glass type (hollow or laminate), hardware brand, and opening method.
3. What hardware brands are used and are they durable?
We use premium hardware systems from world-renowned brands such as HOPO, Gewu, and Siglia, ensuring high strength and corrosion resistance.
4. What is the warranty period for these windows?
We offer a comprehensive 20-year overall warranty, a 10-year warranty for hardware, and a 10-year warranty against glass self-destruction.
5. Does the concealed drainage really prevent leaks?
Absolutely. The hidden drainage system discharges rainwater more reliably than traditional holes and significantly reduces the risk of backflow during strong winds.
6. How does the window achieve high sound insulation?
It utilizes a multi-cavity bridge-cut aluminum profile combined with a triple-seal design, which effectively isolates external noise and enhances thermal efficiency.
