Fireproof glass has good transparency and fire resistance, and is mainly used in fire separation openings and atriums, as well as in local firewall openings.
1. Classified by structure
Fire resistant glass can be divided into composite fire resistant glass and single piece fire resistant glass:
Special glass (represented by FFB) that meets the fire resistance requirements and is composed of two or more layers of glass composite or another layer of glass and organic materials composite..
Single layer fire-resistant glass (represented by DFB) is a special type of glass that consists of a single layer of glass and meets the corresponding fire resistance requirements.
2. Classified by fire resistance performance
Fireproof glass can be divided into heat-insulating fire-resistant glass (Class A) and non heat-insulating fire-resistant glass (Class C), abbreviated as Class A fire-resistant glass and Class C fire-resistant glass:
Insulating fire-resistant glass (Class A) is a fire-resistant glass that meets both the requirements of fire integrity and fire insulation.
Non insulating fire-resistant glass (Class C) is a fire-resistant glass that only meets the requirements for fire integrity.
3. Classified by fire resistance limit
Fireproof glass can be divided into five levels: 0.50h, 1.00h, 1.50h, 2.00h, and 3.00h.
At present, Huayou Glass provides customers with fire-resistant glass with a fire resistance rating of 2 hours
2-hour fire-resistant glass is a special type of glass that can maintain integrity and insulation for up to 2 hours in the event of a fire. It is generally used for fire separation in buildings, such as firewalls, fire doors, fire windows, etc.
This type of glass is usually composed of multiple layers of glass and an intermediate fireproof layer, which can be transparent inorganic materials such as aluminum silicate, magnesium oxide, etc. In the event of a fire, fire-resistant glass can effectively prevent the spread of flames and smoke, as well as prevent the transfer of heat, thus protecting the safety of personnel and property.
2-hour fire-resistant glass has high transparency and will not affect the lighting and visibility of buildings. It also has strong impact resistance and stability, and can remain intact in a fire without breaking or falling.
It should be noted that the quality and performance of 2-hour fire-resistant glass are very important and must comply with relevant national standards and specifications. When selecting and using fire-resistant glass, it is important to choose a reputable manufacturer and product. In this regard, Huayou Glass has always strictly controlled quality testing and conducts strict quality testing on its products before leaving the factory, including tests on appearance, size, light transmittance, fire performance, etc., to provide high-quality products to customers. In addition, fire-resistant glass should be installed according to the correct installation method to ensure its fire resistance and safety. At the same time, it is also important to regularly maintain and inspect fire-resistant glass to ensure that it is always in good working condition.
