1. Through the calculation after the renovation of the external wall: the heat transfer coefficient of the external wall has reached 0.45W/㎡.K (the heat transfer coefficient of the external wall is 0.6 W/㎡.K, which is the index of Beijing Energy Conservation 65), which greatly exceeds the standard of Energy Conservation 65. .

2. Information tracking results from November 15, 2010 to March 15, 2011 In the two pilot homes, a total of 4 tons of coal was consumed in a heating season, a 33% reduction from the original, and the average room temperature reached 18.5 degrees.

3. The service life of the metal embossed composite thermal insulation wall panel structure is 50 years, and the service life of the coating is more than 15 years (after 15 years, if you need special repair paint for maintenance, it only needs about 10 yuan per square meter). Compared with the external wall insulation system currently used in the market, the service life of the coating is increased by 4 times; the service life of the structure is 3 times, and the cost performance is excellent, which greatly reduces the maintenance cost after a cycle.
