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.

Class B: fireproof glass meeting the requirements of fire integrity and thermal radiation strength 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 only meeting the requirements of fire resistance integrity. This kind of glass has the characteristics of light transmission, fire prevention, smoke separation and high strength.

Fireproof glass is divided into composite fireproof glass (pouring type and composite type, with good thermal insulation performance of grouted fireproof glass and good fireproof performance of composite fireproof glass) and single fireproof glass.

1. Composite type: it is composed of two or more layers of glass original sheet and one or more layers of water-soluble inorganic fireproof glue interlayer.

2. Monolithic fireproof glass is a kind of fireproof glass with single-layer glass structure.

3. Pouring type: it is composed of two layers of glass original sheets (three layers of glass original sheets can also be used for special needs), and the four sides are sealed with special flame retardant adhesive strips. The fireproof adhesive liquid poured in the middle is in the form of transparent gel after curing and bonded with the glass.

Suiyong glass technology reminds you that single and composite pouring fireproof glass cannot be cut with a glass knife like ordinary flat glass, but must be processed to a fixed length, but the composite (dry process) fireproof glass can meet the cutting requirements.
