Difference between stone wool insulation slab and stone wool insulation belt.

     1. Structure difference: The fiber of stone wool insulation slab is parallel to the surface of slab, and the direction of the fiber of stone wool belt is vertical to the surface of belt.
     2. Dimension difference: Regular dimension of stone wool insulation slab are 600mmx900mmxthickness or 600mmx1200mmxthickness. And its length an be adjusted with in certain extent. But stone wool belt has only one dimension 150mmx600mmxthickness. 
     3. stone wool insulation slab is also called stone wool thermal insulation decorative board. Generally used for exterior wall decoration of buildings, thermal insulation and sound insulation of industrial equipment, buildings, ships, etc.
     stone wool belt has stronger tensile strength and compressive strength, and it has a higher safety factor for external wall insulation. It is suitable for pipeline heat preservation and heat insulation in the electric power, petroleum, metallurgy, and shipbuilding industries, especially suitable for the insulation of small straight pipelines.
