Fireproof glass is a kind of special glass that can maintain its integrity and thermal insulation in the prescribed fire resistance test, and is divided into three categories according to the fire resistance performance grade.
Fireproof glass is a kind of special glass that can maintain its integrity and thermal insulation in the specified fire resistance test. It is divided into three categories according to the fire resistance rating:
Class A fireproof glass that meets the requirements of fire-resistant integrity and fire-resistant insulation at the same time. This kind of glass has light transmission, fire prevention (smoke, fire, heat radiation), sound insulation and impact resistance. It is suitable for building decorative steel and wood fire doors, windows, upper lighting, partition walls, daylighting roofs, smoke blocking vertical walls, perspective floors and other building components that need to be both transparent and fireproof.
Class B fireproof glass that meets the requirements of fire integrity and thermal radiation intensity at the same time. Such fireproof glass is mostly composite fireproof glass with light transmission, fire prevention and smoke isolation characteristics.
Class C fireproof glass that only meets the fire integrity requirements. This kind of glass has the characteristics of light transmission, fire prevention, smoke isolation and high strength. It is suitable for fireproof glass partition walls, fireproof windows, outdoor curtain walls, etc. without thermal insulation requirements.
From the structure, fireproof glass is divided into composite fireproof glass and monolithic fireproof glass.
