Phoenix brand of exterior wall thermal insulation rock wool board is designed for building external wall insulation system of thin plastering, apply to the foundation walls are concrete or brick wall, dense structure of new or existing building exterior wall insulation and energy-saving; the external wall thermal insulation rock wool strip can also be used as fireproof isolation belt, and the combustion performance of a level of less than the insulation supporting the use of materials, to improve the external walls of the building fire protection function. 
It has high compressive and tensile strength, and lower moisture absorption, good dimensional stability, will not produce thermal expansion or contraction, aging resistance and other advantages, can be compatible with the exterior wall system, provide effective energy-saving insulation, fire and extreme climate protection and many other kinds of performance of buildings.
