Design Philosophy

Our products are designed with core principles of energy efficiency, durability, and user comfort. We fully consider harsh construction site conditions and follow full-life-cycle reliability standards to deliver stable, low-maintenance, cost-effective solutions for clients.

Technical Principles

The core working principle of our aluminum alloy doors and windows is based on broken-bridge thermal barrier technology, which interrupts heat conduction paths through structural design. The complete implementation logic is as follows:
1. Broken-bridge aluminum profiles separate the inner and outer aluminum frames with a thermal insulation strip, blocking heat transfer between indoor and outdoor environments
2. Multi-layer insulated tempered glass with Low-E coating reduces heat radiation and blocks ultraviolet rays, enhancing thermal insulation and noise reduction
3. EPDM sealing strips and precision hardware components ensure airtight and watertight performance, preventing water leakage and dust infiltration

Core Architecture & Innovative Design

We have optimized the system architecture with modular design to improve performance and adaptability:
1. Broken-Bridge Thermal Insulation Profile Module: Separates inner and outer frames with PA66 thermal strips, reducing heat transfer by over 30% compared to traditional aluminum profiles
2. Multi-Layer Insulated Glass Module: Combines double/triple tempered glass with inert gas filling, achieving noise reduction of 35-45 decibels
3. Sealing System Module: Uses EPDM rubber strips with high elasticity and aging resistance, maintaining airtightness for over 15 years
