Hello! Manager! The fire endurance of the rock wool laminboard is generally two hours. If you need the fire?rating of the rock wool laminboard, then I recommend you to buy it from the standard factory ! The one with higher fire rating can use polyurethane edge banding rock wool board and handmade glass magnesium rock wool laminboard.
Hello. The fire endurance now on the market is generally about two hours. The 50mm color steel sandwich version of Bo magnesium rock wool, with refractory time being five or six hours, is very good.
