BAIJIAN - Third party testing organization
According to the structural type、 it can be divided into fireproof laminated glass、 thin coated fireproof glass、 single piece fireproof glass、 and fireproof laminated glass. Among them、 fireproof laminated glass can be divided into composite fireproof glass and poured fireproof glass according to the production process characteristics
Divided by fire resistance limit
Divided into 5 levels based on fire resistance limit: 0.5h、 1.00h、 1.50h、 2.00h、 3.00h.
Classified by fire resistance performance
Insulated fireproof glass (Class A) and non insulated fireproof glass (Class C).
