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.

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(gè)等級(jí):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.
