Insulation performance: good insulation properties are rock wool, slag wool products, basic characteristics, conditions at room temperature (25 ℃ or so) their thermal conductivity is usually 0.03 ~ 0.047W / (moK) between. 2. Combustion performance: rock wool, slag wool products, combustion performance depends on how much of which flammable adhesive. Rock wool, slag wool is an inorganic silicate fibers, non-flammable, processed into products in the process, sometimes adding an organic binder or additives, combustion performance of these on the product will have a certain impact.
