Study of building structural system for the external thermal insulation technology, many foreign engineers developed dozens of different wall insulation system, such as EIFS(exterior insulation finishing system), in the mid 1980s in China, under the influence of insulation enterprise in foreign countries, the external insulation technology began to research, At present, China prepare the industry standard issued by the recommended industry standard exterior insulation systems: EPS thin plaster external thermal insulation system, insulating mortar consisting of gelatinous powder and EPS pellets insulation system, cast-in-situ concrete composite no nets EPS exterior insulation system, cast-in-situ concrete composite EPS wire rack boards exterior insulation system, mechanical fixed EPS steel mesh exterior wall insulation system [2].
At present, the external foam glass thermal insulation system has been applied in engineering and promotion [3, 4], but on the whole still in the stage of technology development and research applications [5, 6].
