The insulation building materials industry covers a wide range of areas, mainly divided into outdoor wall insulation and indoor pipe insulation. The rubber and plastic insulation materials in indoor air-conditioning insulation are only one of the subdivision materials, mainly applied to the central air-conditioning ventilation pipe and condensate pipe. It belongs to an auxiliary material in the electromechanical installation sub-contract of the project. However, for the overall thermal insulation building materials industry, the overall trend, the market capacity is still expanding, because the most basic two aspects, one is linked to real estate, one is linked according to national requirements.
The thermal insulation building materials industry is classified as an energy-saving industry required by the state, and the quality of building energy-saving construction is clearly defined. All buildings are set up for acceptance and all parts of the building are currently subject to project completion and acceptance. Building energy conservation must be checked first, that is to say, building energy conservation must be first accepted, and the subsequent branch engineering acceptance is allowed after acceptance. At present, the energy conservation acceptance must be attended by the local engineering quality supervision department, and the on-site inspection report of the heat transfer coefficient of the enclosure structure must be issued.
The building materials industry is greatly affected by real estate. For example, after the slowdown in real estate development in 2014 and 2015, the growth rate of the building materials industry is also declining. Therefore, the thermal insulation building materials industry relies on the real estate industry to be relatively close, and the growth rate will be affected. At the same time, insulation materials will also be involved in the renovation of old houses.
According to statistics, it is widely used as a thermal insulation material for roofs, walls, ceilings, floors, doors and windows of buildings in European and American countries. About 49% of building insulation materials in developed countries such as Europe and America are aerogel insulation materials, while in China it is less than 10%. Therefore, there is still a lot of room for the development of aerogel insulation materials in China.
The market for building energy-saving materials in China is large, especially in the market for building insulation materials. The energy loss of Chinese housing is about 50% of the wall; the roof is about 10%; the doors and windows are about 25%; the basement and the ground are about 15%. China's construction industry needs to achieve 70% energy saving rate by 2020. It is necessary to comprehensively renovate the exterior wall of the building, and the market for wall insulation materials will increase substantially.
