 As the third step of the target of 65% of building energy efficiency standards gradually expand, the general insulation products are increasingly difficult to adapt to the requirements of the development of this energy-saving standards. Powder particles of polystyrene insulation mortar due to its own shortcomings, has been banned in some provinces and cities to use. Insulation thickness in the cold weather and cold regions, the EPS board and similar thickness of insulation materials for thermal insulation performance has reached more than 100mm insulation layer is too thick for the safety and reliability of the insulation system (surface material formed shear torque will increase) have certain risks.
