Research progress of building insulation materials at home and abroad

In general, the thermal insulating material is that thermal coefficient is less than or equal to 0.14W/ (m.K), with good heat preservation performance and is widely used in the field of industrial and construction. This paper introduced the main kinds of thermal insulation material, summarized the research progress of thermal insulation materials, introduced the application in building and the research status of the organic heat preservation material, inorganic heat preservation material and composite insulation materials, pointed out that along with the research of thermal insulation material unceasing deepening, the performances of thermal preservation material will continue to improve and be perfect, and make bigger contribution to building energy efficiency.
