Advantages of special rock wool for exterior wall insulation
Apr 25, 2022
Fire protection: the special rock wool for external wall insulation is made of natural rock. It is a non combustible class a fireproof material, which can effectively delay the spread of fire; No toxic gas or molten drops will be produced in the fire.
Thermal insulation: the special rock wool fiber for external wall thermal insulation is slender, with an average diameter of 5 μ m. Superior to national standard ≤ 7 μ M; The slag ball content is low, about 5%, which is much lower than the national standard ≤ 10%, so the thermal conductivity is low and the heat preservation effect is remarkable.
Sound absorption: the special rock wool products for external wall thermal insulation form a porous connected structure with a large number of fibers. By converting sound energy into heat for sound absorption, the sound reflection is greatly reduced, providing an undisturbed and beneficial environment for work and life.
Waterproof: the hydrophobic rate of the special rock wool for external wall insulation is ≥ 99%, and the short-term water absorption (partial immersion for 24h), <0.5kg/m3; If the product is soaked in high-pressure water, it will not affect its performance and expansion after drying.
Environmental protection: the special rock wool for external wall insulation does not contain cfchchfc, which will not damage the ozone layer in the atmosphere; Asbestos free; The water extract of rock wool is neutral or weakly alkaline, and will not damage or corrode the materials in contact with it.
