“External wall insulation and external wall insulation inside have their own strengths and weaknesses and scope, while affected by regional climate and building type of constraints, there is no absolute good or bad, for each block building characteristics and local climate conditions, choose the most suitable insulation system is the key to building energy efficiency. ”

October 10, 2008 China (Qingdao) International Building Energy Efficiency and Renewable Energy Expo exterior wall construction and insulation applications technical forum, experts said, China has cold regions, cold regions, hot summer and cold winter zone, a moderate area and the subtropical region and other five different climate area. This determines our external wall insulation can not be “across the board” must be based on climatic conditions in various regions, selected in accordance with thermal insulation system.

Wall insulation is an important part of building energy efficiency. At present, the insulation system applications from our perspective, building insulation system about 70% of the external thermal insulation system, about 25% of the internal thermal insulation system.

Experts said that before 1999, China’s building insulation is mainly achieved through the external wall insulation system within the. The main external wall insulation system within the expanded perlite thermal insulation materials, polymer mortar and Adhesive Polystyrene thermal insulation. The high thermal conductivity materials, on-site mixing mode of operation makes the actual thickness difficult to control. Plus part of the material manufacturer for the pursuit of high profits, cut corners, making the wall thickness of the insulation often biased, easy to crack. Moreover, some real estate development company to meet the country’s inspection perfunctory, eventually causing the material to be prohibited in some cities or restrict the use of.

In fact, the gypsum board increase in polystyrene insulation system, polystyrene composite gypsum within the thermal insulation system, insulation system within the glass hanging abroad has more than 40 years of application history, technology is mature, safe and reliable performance.

Experts say high-rise buildings, in addition to the form of dry hanging curtain wall systems, for safety and fire considerations within the external wall insulation system should be ideal. Especially in some coastal areas, the typhoon will have a great negative pressure outside the wall, and there have been too windy to blow the insulation layer of the case, especially thin plaster external wall insulation system. So from a security point of view, the external walls of buildings within the insulation system is also ideal for coastal areas.

Some papers and promotional material on the external walls of claims will be condensation inside the wall insulation problems, Saint-Gobain Gypsum Building Materials (Shanghai) Co., Ltd. After several calculations concluded: In the south, almost does not occur within the insulation wall condensation, in the north, as long as reasonable structure, condensation will not occur easily. Will be condensation and indoor relative humidity, temperature, and the minimum wall temperature of the inner surface, as long as the minimum temperature is greater than the external walls of the inner surface of the particular climatic conditions of condensation temperature, condensation does not appear the case.
