The of fireproof glass is divided according to fire resistance limit

Fireproof glass is a special building material, that is, it has the light transmission function of ordinary glass, high temperature resistance, flame retardant and other fireproof functions.

According to the fire resistance of fireproof glass, it is divided into three categories: A, B and C. Class A: fireproof glass meeting the requirements of fire integrity and fire resistance and heat insulation at the same time. Class B: fireproof glass meeting the requirements of fire integrity and thermal radiation strength at the same time. Class C: fireproof glass that only meets the fire integrity requirements.

Fireproof glass is a kind of special glass with good fire resistance performance. In case of fire, it can not lose its function of blocking flame and smoke and isolating high temperature for a long time.

According to fire resistance limit:

Class I - not less than 90 minutes;

Class II - not less than 60 minutes;

Class III - not less than 45 minutes;

Level IV - not less than 30 minutes.

As a member of safety glass, fireproof glass not only has some properties of ordinary glass, but also has gradually been favored by people for its performance of preventing fire spread and heat insulation.
