The broken bridge aluminum window is an aluminum casement window whose products meet NFRC, AS2047, and CE standards, built for project buyers evaluating thermal break aluminum window solutions.
- Multi-cavity frame structure and high-performance sealed glazing system
- Custom color matching services support project-specific design requirements
- 100% full inspection before shipment
Product Details
The broken bridge aluminum window is built with a thermal break aluminum profile at 1.8MM thickness and 75MM frame width, incorporating a multi-cavity frame structure and a DERCHI insulation strip that interrupts heat conduction between interior and exterior aluminum sections. Double tempered glass filled with argon gas is sealed using a PVDF aluminum strip in a 5mm+20A+5mm configuration, and the window operates through outward opening or awning action driven by a stainless steel friction hinge with multiple pivot points, ergonomic in-house lever handles with two base style options, and customized lock points and lock bases. The production sequence covers surface treatment, profile processing and cutting, glass cutting with aluminum strip installation, opening panel installation, frame and casing assembly, troubleshooting and sealing, and packing.
Procurement teams should select from seven glass configuration options including single, double, triple, laminated, and frosted variants with specific setups such as 5MM+27A+5MM and 5MM+12A+5MM+12A+5MM, and confirm whether the Black Skin standard inventory finish meets project color requirements or a custom finish is needed. Specification should account for thermal insulation performance, sound insulation and noise reduction, anti-condensation and frost features, and waterproof and drainage system design against the project's climate and acoustic conditions. The 10-year warranty covering frame unfading and hardware operation, the 25-35 day delivery after deposit and drawing confirmation, and the 100% full pre-shipment inspection define the acceptance and timeline parameters for order placement.

Basic Parameters
| Performance Dimension | Product Value / Status | Meaning & Test Evidence to Request |
|---|---|---|
| Thermal Insulation | Standard DERCHI insulation strip | Thermal insulation should be compared using the declared rating, test method, specimen configuration, and project boundary conditions. Request the applicable thermal test or simulation report and the declared product configuration. |
| Wind Pressure Resistance | Upgraded profile rigidity satisfies stringent wind load standards of high-rise commercial buildings and super high-rise residences | Wind pressure resistance should be reviewed against the specified test pressure, specimen size, anchorage, and acceptance criteria. Request the wind-pressure test report and confirm the tested specimen and installation conditions. |
| Water Tightness | Requires testing for the target project | Water tightness should be reviewed against the test pressure, spray exposure, specimen configuration, and leakage criteria. Request the water-penetration test report and confirm the tested pressure and assembly configuration. |
| Air Tightness | Requires testing for the target project | Air tightness should be reviewed against the pressure differential, specimen area, reporting units, and tested configuration. Request the air-leakage test report and confirm its pressure and specimen configuration. |
| Sound Insulation | 35 dB | Sound insulation should be compared using the stated laboratory method, specimen construction, glazing, and reported acoustic metric. Request the acoustic test report and confirm that the tested construction matches the proposed configuration. |

FAQ
What must be confirmed technically before ordering broken bridge aluminum windows?
Buyers must confirm drawings, dimensions, quantity, frame color, and glass type, as pricing is based on these specific requirements. The window system supply includes profile, hardware, accessories, and glass as a complete package. Custom color matching is available for project-specific design requirements, while Black Skin is the standard inventory color for immediate availability on standard orders.
What should buyers prepare for volume procurement?
Buyers should prepare project drawings, dimension schedules, quantity requirements, frame color specifications, and glass type selections before requesting a quote. Delivery takes 25–35 days after deposit and drawing confirmation. Products can be tested and certified per buyer requirements. A 10-year quality warranty applies. 100% full inspection is conducted before shipment.
What is the difference between broken bridge aluminum and standard aluminum windows?
Broken bridge aluminum profiles use a thermal break strip between interior and exterior aluminum sections to reduce heat transfer through the metal frame. This construction can reduce approximately one-third of the heat lost through the window frame and maintain indoor window surface temperatures above 12–13°C. Standard aluminum frames lack this thermal barrier and conduct heat directly between indoor and outdoor environments.
How does broken bridge aluminum improve sound insulation?
The thermal break construction combined with insulating glass reduces noise transmission through the window assembly. Air sound insulation can reach 30–40 dB, with noise reduction exceeding 30 dB in tested configurations. For projects near highways or dense urban areas, confirm the specific glass configuration and sealing system to meet project acoustic targets.
What color and finish options are available?
Black Skin is the standard inventory color available for immediate availability on standard orders. Custom color matching services support project-specific design requirements. Wood grain finishes and dual-color options for interior and exterior surfaces are available as market-standard configurations; confirm whether these finishes are needed for your project before placing an order.
What is included in the window system supply?
The window system supply includes profile, hardware, accessories, and glass. Products are delivered as finished products ready for installation. Engineering and supervising service is available for installation guidance. Confirm whether installation support is required for your project site when placing the order.
