Influence of fireproof glass window on fire

The fire on the exterior wall of high-rise buildings in 2016 made us wise about the terrible nature of high-rise fire. If the glass of burning buildings is fireproof, it can effectively prevent the extension and penetration of fire and smoke into the building, prevent the window glass from becoming the combustion channel of fire after being split by fire, cause internal fire and develop into a composite three-dimensional fire, Ensure life and industrial safety inside the building.

In fact, the contact between this kind of thermal insulation material and fireproof glass window has been preliminarily implemented, but in terms of technical methods, we should adopt the method of multiple technology combinations when vigorously promoting building energy conservation and emission reduction with regard to the fire rating, height, application status of different buildings, China's national conditions and the industrial technology status of external wall thermal insulation materials, Reach the corresponding fire safety level.

In addition, it is assumed that there is no window wall and window sill wall for the floor external window of the building. In order to prevent the extension between fire floors, the constraint of fire resistance function of no less than 1 hour shall be set. When it is necessary to set fire isolation belt, a class a thermal insulation material with a width of no less than 300mm shall be set along the floor direction. The fireproof isolation belt and the fireproof glass window on the wall shall be pasted in a full area.

Thermal insulation materials, whether external walls or internal walls, qualified fire insulation materials and useful fire protection layout system can effectively control the extension of fire, fully reach the class a fire protection standard of thermal insulation materials stipulated in Gongtong Zi [2009] No. 46 document jointly issued by the Ministry of public security and the Ministry of housing and urban rural development, and can adhere to the weather resistance at a high temperature of 1200 degrees. In addition, the fireproof glass window can basically isolate the extension of fire and make it seamless and pluggable.
