(Summary description)The number of existing buildings in my country is huge. According to incomplete statistics, there are about 40 billion square meters of external wall buildings in the country, of which cities and towns account for about 13 billion square meters. And it is still growing hundreds of millions every year. 99% of existing buildings are non-energy-saving buildings (that is, there is no external wall insulation). According to statistics from relevant departments, building energy consumption accounts for about 27.6% of the total energy consumption of the whole society, and it is even greater in cold regions, accounting for 40%. As the urbanization process accelerates and building energy consumption continues to increase, external wall insulation engineering has become one of the important methods for energy conservation and consumption reduction.
There are three main types of insulation systems currently used in construction: exterior insulation, exterior insulation, and sandwich insulation. In the past, external wall internal insulation technology was prevalent, external wall external insulation was in the experimental stage, and there was basically no external wall sandwich insulation. In recent years, the external insulation system of the external wall has been welcomed by people, and it has gradually become the mainstream thermal insulation system, and the internal insulation of the external wall has been significantly reduced. The external insulation materials are also diverse, polystyrene foam board, silicate composite slurry, rock wool slag wool, glass wool, foam glass, polyurethane foam board, phenolic board, extruded plastic board, integrated board, metal Surface integrated board, etc.
