3. The prices of12mm, 25mm, 35mm and 62mm are 19 14, 5544, 6534, 19800 (Yuan/m2) respectively. Note: This kind of fire-proof glass can reach Class A fire protection of 6090000.
4. The price of borosilicate fire-retardant glass (6mm, 12mm) is 4950, 1 1550 (RMB/m2) respectively. Note: this kind of fire-proof glass has a fire resistance of 180 minutes, which is Class C.
Fireproof glass partition: divided into Class A and Class C;
Class A, fireproof glass partition that is both fireproof and heat-insulating, that is to say, there will be no bright smoke and open flame, and there will be no thermal radiation. The maximum temperature at a single point on the back fire surface of glass partition shall not exceed 180 degrees, and the average temperature at multiple points shall not exceed 140 degrees.
Class A is divided into Class A, Class B and Class C, with Class A fire protection and heat insulation 1.5 hours, Class B 1 hour and Class C 0.5 hours. If necessary, you can make fire-proof partitions for 2 hours and 3 hours.
Class C, fire-proof glass partition, only fire-proof but not heat-insulating, can't pass through an open flame when it is on fire, but thermal radiation will penetrate and ignite flammable materials such as paper, hair and sponge. Class C fireproof glass partitions are not divided into Class A, Class B and Class C, and only time is divided. When it comes to Class A, Class B and Class C, it must be Class A fireproof glass partition.
The quotation to the company is purely hand-punched, and I hope it will be adopted.
