Fire separation shall be carried out with the surrounding connecting space: when fire partition wall is adopted, its fire resistance limit shall not be lower than 1.00h; When glass wall is adopted, its fire resistance and heat insulation and fire resistance integrity shall not be lower than 1.00h, when adopting non-thermal insulation fire protection glass wall with fire integrity not less than 1.00h, automatic sprinkler system should be set for protection; When adopting fire shutter, its fire resistance limit should not be less than 3.00h, and shall comply with the provisions of Article 6.5.3 of this specification; Doors and windows connected with atrium shall adopt Class A fire doors and windows that can be closed by themselves during fire;
The door glass of the shopping mall is divided into the inner door glass and the outer door glass of the building. It can be sure that the door surface connected with the pedestrian street needs to adopt fireproof glass, and whether the inner door glass adopts fireproof glass is carried out according to the design drawing. No matter whether the facade of the shopping mall is designed in the way of partition or door, it must meet the corresponding fire resistance rating specified in the document (Class A fire-proof glass door, Class B fire-proof glass door, etc.), and the glass design must be fire-proof glass, fire-proof glass has monolithic, composite, hollow, laminated and other types, which can be selected according to requirements.
Due to the large area of the glass, the glass is tempered only when it is easily broken and hurtful. Therefore, 8mm thick glass is generally required to achieve the strength to withstand external forces. Sand blasting first and then tempered is tempered frosted glass.
The thickness of tempered glass is generally determined according to the purpose and specifications. The following specifications are specific.
Frame, safety glass, area ≤ 0.5m2, ordinary annealing glass, frameless, thickness ≥ 10mm tempered glass, sports or fitness, place Glass, frame, thickness ≥ 5mm tempered glass or thickness ≥ 6.38mm laminated glass, frameless, thickness ≥ 10mm tempered glass, bathroom glass, framed, safety glass, frameless, except outside door: thickness ≥ 5mm tempered glass, door: tempered glass with thickness ≥ 10mm, railing glass, without horizontal load.
Thickness ≥ 5mm tempered glass or thickness ≥ 6.38mm laminated glass

Supply steel wooden fireproof door (fire glass)
A single piece of cadmium potassium fireproof glass is ion exchange for more than 20 hours under high temperature through special chemical treatment, replacing the metal sodium on the glass surface to form a chemical toughened stress layer. At the same time, after physical treatment, high-strength compressive stress is formed on the surface of the glass, which greatly improves the impact strength. When the glass is broken, it presents a tiny particle state, reducing damage to human body! The strength of a single piece of cadmium potassium fireproof glass is 6-12 times that of ordinary glass and 1.5-3 times that of tempered glass! The thermal conductivity of a single piece of cadmium potassium fireproof glass is 1.13W/m℃.
