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

     1. Structure difference: The fiber of rock wool insulation slab is parallel to the surface of slab, and the direction of the fiber of rock wool belt is vertical to the surface of belt.
     2. Dimension difference: Regular dimension of rock wool insulation slab are 600mmx900mmxthickness or 600mmx1200mmxthickness. And its length an be adjusted with in certain extent. But rock wool belt has only one dimension 150mmx600mmxthickness. 
     3. Rock wool insulation slab is also called rock wool thermal insulation decorative board. Generally used for exterior wall decoration of buildings, thermal insulation and sound insulation of industrial equipment, buildings, ships, etc.
     Rock 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.
