there are five main kinds of fireproof glass, one is sandwich composite fireproof glass, the other is fireproof glass with wire, the third is special fireproof glass, the fourth is hollow fireproof glass, and the other is high strength single-layer fireproof glass with single-layer caesium and potassium.
can the fireproof glass be divided into several grades according to the fire resistance?
fireproof glass is a kind of special glass that can maintain its integrity and heat insulation in the prescribed fire test. it can be divided into three categories according to fire resistance rating.
a class of fire-resistant glass that meets the requirements of fire integrity and fire insulation. this kind of glass is transparent, fireproof (smoke proof, fire proof, shielding thermal radiation), sound insulation and impact resistance. it is suitable for building decoration steel wood fireproof door, window, upper bright, partition wall, lighting roof, smoke retaining wall, perspective floor and other building components that need transparent and fireproof.
the b class also meets the requirements of fire integrity and thermal radiation requirements. such fireproof glass is mostly composite fire resistant glass, which has the characteristics of light transmission, fire prevention and smoke isolation.
class c only meet fire integrity requirements of fireproof glass. such glass has the characteristics of light transmission, fire prevention, smoke isolation and high strength. it is suitable for fireproof glass partition walls, fire windows and outdoor curtain walls without thermal insulation requirements. in terms of structure, fireproof glass can be divided into compound fireproof glass and monolithic fireproof glass.
