Comparing directional rock-wool board to ordinary rock-wool board, directional rock-wool board has the characteristics of low bulk density, high strength, convenient construction, environmental protection and so on. The directional rock wool board is suitable for the curtain wall system of residential, commercial and industrial buildings.

Compared with the ordinary curtain wall rock-wool board (which is around 80kg/ m³~100kg/ m³), the self weight of directional rock-wool board is reduced by more than 15%. It is more convenient to carry and it can make the construction easier. It has high tensile strength and higher resistance to wind pressure. The overall strength is higher than ordinary rock-wool, and the construction is not easy to be damaged. The directional rock-wool board has lower bulk density makes it more flat in construction. It has A (A1) non combustible material and can be not melted at high temperature at 1000. It has good sound insulation and sound absorption performance; the fiber used is nontoxic and does not contain asbestos, and it does not damage the health of the human body. The directional rock-wool is not flammable, no release of toxic smoke, can be used safely; it has high dimensional stability, even under fire and high temperature, can maintain material stability, excellent permeability and no corrosion to various components in metal materials and buildings. The physical and chemical properties are very stable. The production process does not need foaming agent and flame retardant, and has a worldwide recognition of excellent sustainability.
