Fire-proof glass is divided into composite fire-proof glass (National Standard Class A) and monolithic fire-resistant glass (National Standard Class C). Composite fire-proof glass is divided into pouring composite fire-proof glass and multi-layer composite fire-proof glass, these two kinds of glass can not only prevent open flame and smoke, but also effectively block heat radiation, keep the average temperature of the back fire surface no more than 140 degrees Celsius, and ensure the safe evacuation of personnel; there are monolithic fire-resistant glass caesium potassium monolithic fire-resistant glass and borosilicate fire-proof glass, which can effectively block the diffusion of flame and smoke, but cannot block thermal radiation. Fireproof glass is priced by square meter, generally several hundred yuan per square meter, thousands of good ones. It is recommended that you choose the appropriate fireproof glass according to your actual needs and economic ability.
The fire prevention time of fire-proof glass is different and the price is different: 145 yuan/square meter for 90 minutes fire prevention, 155 yuan/square meter for 120 minutes Fire Prevention; The production cost of glass deep processing products varies from place to place, and the price is also different, the above price is the ex-factory price in Nanchang, Jiangxi province, and there may be a fluctuation of about 15% in other places.
The prices of different fire levels of 12mm single sheet of cadmium potassium tempered fire glass are different: the fire prevention time is 60 minutes 140 yuan/square meter; 90 minutes 155 yuan/square meter; 180 minutes 170 yuan/square meter, the ex-factory price does not include freight and taxes,
