Classified by product type


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


Fireproof glass


Fireproof glass


Class A


Fireproof glass that meets both fire integrity and fire insulation requirements. Including two types of fire-resistant glass: composite fire-resistant glass and poured fire-resistant glass. This type of glass has transparency, fire resistance (smoke, fire, and heat radiation shielding), sound insulation, and impact resistance, and is suitable for building decoration steel wood fire doors, windows, ceilings, partition walls, skylights, smoke barriers, see through floors, and other building components that require both transparency and fire resistance.


Class B


Fireproof glass that meets both fire integrity and thermal radiation intensity requirements. This type of fire-resistant glass is mostly composite fire-resistant glass, which has the characteristics of transparency, fire resistance, and smoke isolation.


Class C


Single piece fire-resistant glass that only meets the requirements of fire integrity. This type of glass has the characteristics of transparency, fire resistance, smoke isolation, and high strength. Suitable for fire-resistant glass partition walls, fire-resistant windows, outdoor curtain walls, etc. without insulation requirements.


Classified by structural type


Divided into fire-resistant laminated glass, thin coated fire-resistant glass, single piece fire-resistant glass, and fire-resistant laminated glass. Fireproof laminated glass can be divided into composite fireproof glass and poured fireproof glass according to the production process characteristics.


Classified by fire resistance limit


According to the fire resistance limit, there are 5 levels: 0.5h, 1.00h, 1.50h, 2.00h, and 3.00h.


Classified by fire resistance performance

  隔熱型防火玻璃(A類)和非隔熱型防火玻璃(C類)。
