External wall thermal insulation rock wool board characteristics:
1, heat insulation performance: good heat insulation performance is a basic characteristic of rock wool, slag wool products, under the condition of normal temperature (25 degrees Celsius) rock wool thermal conductivity is usually 0.03 ~ 0.047W/ (moK).
2, the combustion performance: rock wool, slag wool products of combustion performance depends on how much the combustible adhesive. Rock wool, slag wool belongs to inorganic mineral fiber, nonflammable, processed into products in the process, sometimes adding organic binder or additives, will influence the combustion performance of these products.
3, sound insulation performance: rock wool, slag wool products with excellent sound insulation and sound absorption performance, the sound absorption mechanism is this kind of products with the porous structure, when sound waves through, because of the effect of flow resistance of friction, part of the sound energy is absorbed by the fiber, hampered by the acoustic wave transmission.
