What are the requirements for glass in fire windows? In fact, frameless fireproof glass and glass used in general windows are two different classifications, and the requirements must not be unified. There are some special points. The tempered glass with better quality in general glass is actually a kind of prestressed glass. In order to add the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is offset first, so as to improve the bearing capacity and enhance the tolerance of the glass itself, and can resist wind pressure, cold and heat, impact, etc.

The main advantages of frameless fireproof glass are two: first, the strength is several times that of ordinary glass. The second is the use of safety. The added bearing capacity improves the brittleness. Even if the tempered glass is damaged, there are no small fragments and acute angles, and the damage to the human body is greatly reduced.

The fireproof glass used in the fireproof window is mainly used to control the extension of fire or smoke. It is a kind of fireproof material. After fire resistance evaluation, the fireproof effect is evaluated. Fireproof glass is a special type of glass that maintains its integrity and thermal insulation during the specified fire test. It is divided into three categories according to fire resistance rating:

Class a fireproof glass meets the requirements of fire integrity. It includes composite fire-proof glass and poured fire-proof glass. This kind of glass needs light transmittance, fire prevention (smoke, fire, block heat radiation), sound insulation and impact resistance. It is suitable for the construction and decoration of steel fire doors, windows, bright, partition walls, lighting tops, block smoke walls, perspective floors and other building components requiring transparency and fire protection.

Class B marine fireproof glass, including sidescuttle fireproof glass and rectangular window fireproof glass. The outer surface glass plate is tempered safety glass, and the material type of inner surface glass plate can be selected arbitrarily.

Class C single piece fireproof glass only meets the integrity requirements of fireproof windows

This glass has high light transmittance, fire prevention, smoke-free and high strength. It is suitable for fire compartment walls without insulation requirements, fire windows, outdoor curtain walls, etc. structurally, fire-proof glass is divided into composite fire-proof glass (infusion type and composite type) and single piece fire-proof glass.
