There are many materials used to manufacture fire-resistant windows, and currently, broken-bridge aluminum is the most popular choice. Broken-bridge aluminum offers numerous advantages: it not only has excellent fire resistance but also provides outstanding sound insulation. It is often used for exterior walls of buildings. Most importantly, it can fully meet the requirements of relevant Chinese standards and fire safety inspection criteria.

The newly issued 2014 Code for Fire Protection Design of Buildings GB50016-2014 explicitly stipulates requirements for residential buildings taller than 54 meters, mandating the addition of refuge rooms.

In residential buildings with a height exceeding 54 meters, each household shall have one room that meets the following requirements:

1. The room shall be located adjacent to an exterior wall and equipped with operable exterior windows;

2. The fire-resistance rating of interior and exterior walls shall not be less than 1.0 hour; exterior windows should preferably be fire-resistant windows with a fire integrity rating of at least 1.0 hour.

Currently, the aluminum alloy energy-saving and fire-resistant windows we produce meet the fire resistance requirement of 1.0 hour for window frames. Our company has invested manpower, resources, and dedicated facilities to develop an aluminum alloy energy-saving window—based on break-bridge aluminum (aluminum alloy) windows—that combines the fire-resistant properties of our original steel fire-resistant windows, achieving a fire integrity rating of 1.0 hour.

The fire-resistant windows have now passed the fire safety inspection and testing successfully. This type of break-bridge aluminum (aluminum alloy) fire-resistant window complies with national regulatory requirements and fire safety testing standards.
