Exterior wall insulation extruded board cold storage special extruded board

The difference between ordinary board and flame-retardant board is whether there is flame retardant added, and the weight is slightly lighter: flame-retardant board is more than 3 kilograms per square, and ordinary board is only about kilograms. "The price of flame retardants is very high, so the cost of flame retardant boards has also increased significantly." The flame retardant effect of ordinary boards without flame retardants is not good, and it can even be said that the flame retardant rate is zero. The price of this kind of board is relatively cheap. It is 3 yuan per cubic meter and has various specifications, from centimeter to centimeter, etc., and its prices are different. Flame-retardant boards are divided into B and B grades. For details, see (Old Standard). Flame-retardant boards have high production technology requirements and good flame-retardant effects. They can effectively ensure construction safety and reduce project risks and losses. Therefore, the Ministry of Construction and the Ministry of Public Security A joint document stipulates that walls with non-fire-retardant panels are prohibited. Because the project cost will increase, many project construction methods take risks, which makes the project safety problem very serious. Sales Phone 3 Manager Wang
