According to the structure of fire resistant glass can be divided into compound and monolithic. Compound: composed of two or more layers of glass sheets attached to one layer or multiple layers of water-soluble inorganic fireproof adhesive interlayer. Principle of fire prevention: When a fire occurs, the glass on the fire surface will burst soon after encountering high temperature, and its fireproof adhesive sandwich will expand by about ten times successively to form a hard milky bubble-shaped fireproof adhesive board, which can effectively block the flame and isolate the high temperature and harmful gases. The finished product can be edged, punched and cut with ruler. When applied to the outer window and curtain wall, the design scheme should consider the combination of fireproof glass and PVB laminated glass. Scope of application: building room, corridor, passage of fire doors and Windows, fire partition and important parts of the fire partition wall.

Monolithic type: monolithic fire resistant glass is a single layer glass structure of fireproof glass. In a certain period of time to maintain fire integrity, block the face of fire and toxic, harmful gas, but does not have temperature insulation effect. It is suitable for exterior curtain wall, outdoor window, lighting roof, smoke retaining wall, fireproof glass frameless door, and partition wall without insulation requirement.

The following points should be paid attention to when using fire resistant glass:

1. Before choosing fireproof glass, we should first clear the specific requirements of fire protection components composed of fire resistant glass, such as fire prevention, heat insulation or smoke isolation, fire resistance limit requirements, etc.

2. Monolithic and composite perfusion type fireproof glass can not be cut with glass knife like ordinary flat glass, must be fixed length processing, but composite (dry method) fire resistant glass can meet the requirements of cutting.

3. When choosing fire resistant glass to form fireproof components, in addition to considering the fireproof durability of glass, its supporting structure and each element must also meet the needs of fire resistance.
