1. The difference between ordinary board and flame retardant board is whether there is flame retardant added.
2. The flame-retardant board is more than 32 kg per square, and the ordinary extruded board is only about 28-31 kg.
3. The price of flame retardant is very high, so the cost of flame retardant board is also greatly increased. The flame retardant effect of ordinary board without flame retardant 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, 340 yuan per cubic meter.
4. Flame-retardant boards have high requirements for production technology and good flame-retardant effects, which can effectively guarantee construction safety and reduce project risks and losses. The cost of the project will increase, and many project construction parties will take risks, which makes the project safety problem very serious.
