At present, fire windows are used in all projects, which has brought a great degree of maintenance to our life. The glass used in the fire windows produced by the manufacturer is fire-proof glass, which plays a major role in controlling the extension of fire or smoke separation. It is a measure type fire-proof material, and its fire-proof function is evaluated by fire-proof function. This material is a special glass that can maintain its integrity and heat insulation in the regular fire resistance test through process processing and treatment. The original piece of glass in Chengdu glass doors and windows can be made of float plane glass, tempered glass, composite fireproof glass, or single piece of fireproof glass. The classification of fireproof products is different, and fireproof glass is no exception.

According to fire resistance function

Insulated fireproof glass (Class A), non insulated fireproof glass (Class C) and partially insulated fireproof glass (class B).

Class A

At the same time, fireproof glass meeting the requirements of fire integrity, fire resistance and heat insulation. It includes composite fire-proof glass and cast-in-place fire-proof glass. This kind of glass has the functions of light transmission, fire prevention (smoke, fire and heat radiation), sound insulation and impact. It is suitable for the construction and decoration of steel wood fire doors, windows, upper lighting, partition walls, daylighting roofs, smoke retaining vertical walls, perspective floors and other building components that need to be both transparent and fire-proof.

Class B

At the same time, fire-proof glass meeting the requirements of fire integrity and thermal radiation intensity. This kind of fireproof glass is mostly composite fireproof glass, which has the characteristics of light transmission, fire prevention and smoke separation.

Class C

Only single piece fireproof glass satisfying the requirements of fire resistance integrity. This kind of glass has the characteristics of light transmission, fire prevention, smoke separation and high strength. It is applicable to fireproof glass partition walls, fireproof windows, outdoor curtain walls, etc. without thermal insulation requirements.

According to fire resistance

According to fire resistance5個等級：0.5h、1.00h、1.50h、2.00h、3.00h。

In order to meet the fire protection requirements required by the state, the scale, appearance quality, optical strength and impact capacity of fire-proof windows should comply with the national rules. All kinds of fire-proof glass products should pass the testing of various inspection centers, reach the qualified specifications, and then issue the product qualification certificate. In the future, they can enter the stage of sales and installation.
