[Why are more and more shopping malls using fireproof glass walls instead of ordinary glass walls?]

In China, due to the problem of building fire protection zoning of large venues, fireproof glass walls are widely used in more and more buildings. As a building component with a certain fire resistance limit, fireproof glass walls are used to control and prevent fire from spreading to other parts of the same building along the vertical or horizontal direction, and the formation of building fire protection zoning has been widely recognized. According to relevant codes, the fire resistance rating requirements of buildings are to ensure that buildings will not collapse in a short period of time in a fire. Fireproof glass partition is a part of the building, its role is to ensure that the fire after a certain period of time to remain intact, that is, fire resistance. Therefore, the selection of its fire resistance grade in the design needs to be determined according to the fire resistance grade of the building in which it is located and the fire protection requirements of the part of the building.

What are the advantages of using fireproof glass walls?

Fireproof glass wall belongs to passive fire protection system, its main function is to prevent the spread of fire. There are four ways of building fire spread: flame spread, heat conduction, heat convection and heat radiation, accompanied by the spread of smoke. In addition to the first way is the flame through the direct ignition of combustible materials to make the fire spread, the latter three ways are based on different heat transfer processes to ignite combustible materials and cause the spread of fire. Therefore, the focus of fire partition design is on how to prevent the spread of fire.

According to the way the fire spreads in the building, and the role of the fireproof glass wall, it should have the following basic characteristics:

1. Smoke containment. That is, when the fire occurs, it can prevent the smoke generated by the fire from the side of the fire to the side of the back fire. This is the most basic requirement, reasonable and effective blocking of the smoke generated by the fire, to avoid the formation of a chimney effect, is to control the spread of the fire, to ensure that the evacuation channel is smooth or effective.

2. Fire integrity. That is, when a fire occurs and one side is subjected to fire, it can prevent the flame from penetrating or preventing the flame from appearing on the back fire surface within a certain period of time. According to the design requirements of building fire protection, the fire room wall should have good integrity. If there is a burn that falls, a burn that collapses or fails to meet the requirements of the fire protection time limit, the fire will also spread and the purpose of reducing the fire loss will not be achieved.

3. Fire insulation. That is, when a fire occurs and one side is caught on fire, the temperature of the back fire surface can rise within a certain period of time to avoid igniting the items in the back fire area. If the smoke insulation is satisfied, the integrity is ensured, but due to the heat generated by the fire through the fire glass, a large number of thermal radiation leads to the burning of flammable materials on the back fire surface, and it does not play the role of fire prevention.

Does it apply in Macau?

For the time being, general shopping malls have no fire protection requirements for glass walls, but when fireproof glass walls are used, they can play a preventive role. In the event of a fire, they can protect personnel damage and property losses. If there are fire acceptance requirements, fire insulation glass walls can also be used, which are more beautiful than ordinary walls. It can also meet the functional requirements of fire insulation.
