Rock wool products change due to fiber direction, not only can meet the requirements of fire safety, the tensile strength and compressive strength increase.
岩棉制品因纤维方向发生本质的变化，不但能够达到防火的要求，整体的抗拉强度和抗压强度的提高。

Rock wool is used a variety of natural ore made of inorganic fiber, has excellent fire, sound insulation, heat insulation, water repellency seismic characteristics.
岩棉是用多种天然矿石制成的无机纤维，有优良的防火、隔音、保温、憎水抗震等特性。
