Rock wool board (IB Series) have good strength and heat stability and chemical stability. Meanwhile, it has excellent sound absorption, heat preservation property and with A 1 fire-resistant class.Then we can according to clients demand,produce waterproof and Low chloride rock wool and faced aluminum foil, glass cloth and so on facing material
