Yanghu Refrigeration external wall rock wool insulation board is specially designed for building external wall insulation, with significant advantages and is favored in the market. 

 In terms of heat preservation performance, it performs.  Natural basalt as raw material, made by special technology, low thermal conductivity, can effectively block indoor and outdoor heat exchange.  In winter, it can prevent indoor heat loss and keep indoor warm as spring; in summer, it can resist outdoor heat wave attack, keep indoor cool, greatly reduce energy consumption of air conditioning, heating and other equipment, and save energy significantly. 

 Fire protection is a good idea.  As a Class A non-combustible material, it will not burn or release toxic smoke in case of fire. It can also cut off the spread of flame and gain valuable time for personnel evacuation and fire rescue. It is especially suitable for schools, shopping malls, office buildings and other densely populated public buildings with strict fire prevention requirements. 

 Water and moisture resistance are equally excellent.  The hydrophobic rate exceeds 99%, which can effectively resist rain and moisture. Even in the humid rainy season in the south or in areas with frequent rainstorm, it can ensure that the wall is dry and avoid the problems of thermal insulation performance degradation, wall mildew and falling off caused by moisture. 

 High compressive and tensile strength, good size stability, long-term use will not deform, crack.  Good anti-aging performance, normal use, life up to 35 years, reducing the late frequent replacement, maintenance trouble and cost. 

 Easy installation, light weight and can be cut and sawed, flexible processing according to different building exterior wall shapes and size.  Whether it is a new building or an energy-saving transformation of an existing building, it can be easily installed, with high construction efficiency and greatly shortened construction period. 

 Yanghu refrigeration external wall rock wool insulation board with excellent thermal insulation, fire, waterproof performance, as well as convenient installation characteristics, for building external wall insulation to provide reliable protection, is the ideal choice for building insulation.
