In the process of manufature, rock wool is made better fire proof performance when put in other organic adhesives and agents.2. Heat Insulation. Rock wool has excellent heat insulation, and its thermal conductivity rate ranges from 0.03 to 0.047W/(m¹’k) under normal temperature.3. Sound Insulation. Rock wool has outstanding sound-absorption performance due to its multi-pole structures. Its inner fiber absorbs part of the sound energy and prevents the spread of sound when sound waves tries to pass through.Specs¼š1.Upper and Lower Layers¼šgalvanized steel sheet.
