Fire resistant glass (English Name: anti fire glass, also known as fire resistant glass), which is mainly used to control the spread of fire or smoke. It is a kind of measure fireproof material, and its fire prevention effect is evaluated by fire resistance performance.

There are five kinds of fireproof glass, one is laminated composite fireproof glass, the other is sandwich fireproof glass, the third is special fireproof glass, the fourth is hollow fireproof glass, and the fifth is high-strength single-layer cesium potassium fireproof glass.

By product category

Fireproof glass is a kind of special glass that can maintain its integrity in the specified fire resistance test. It is divided into three categories according to product types:

Class A:

Fireproof glass meeting the requirements of fire integrity, fire resistance and heat insulation at the same time. It includes composite fire-proof glass and cast-in-place fire-proof glass. This kind of glass has the properties of light transmission, fire prevention (smoke, fire and heat radiation), sound insulation and impact resistance. It is suitable for building decorative steel wood fireproof doors, windows, upper lighting, partition walls, daylighting roofs, smoke retaining vertical walls, perspective floors and other building components that need to be transparent and fireproof.

Class B:

Fireproof glass meeting the requirements of fire resistance integrity and thermal radiation intensity at the same time. This kind of fireproof glass is mostly composite fireproof glass, which has the characteristics of light transmission, fire prevention and smoke separation.

Class C:

Single piece fireproof glass that only meets the fire integrity requirements. This kind of glass has the characteristics of light transmission, fire prevention, smoke separation and high strength. It is applicable to fireproof glass partition wall, fireproof window, outdoor curtain wall, etc. without thermal insulation requirements.

By structure type:

It is divided into fireproof laminated glass, thin coated fireproof glass, single fireproof glass and fireproof wire glass. According to the characteristics of production process, fireproof laminated glass can be divided into composite fireproof glass and poured fireproof glass.

According to fire resistance limit:

It is divided into 5 grades according to fire resistance limit: 0.5h, 1.00h, 1.50h, 2.00h and 3.00h.

According to fire resistance:

Insulated fireproof glass (Class A) and non insulated fireproof glass (Class C).
