    With energy conservation and environmental protection requirements continue to increase, insulation technology building maintenance structure also increasingly strengthened, particularly external wall insulation technology has been considerable development and become an important building energy-saving technologies. Currently, the external wall insulation in buildings lowes wood plastic composite siding often used mainly in the insulation, insulation, insulation and other internal and external mixing method, however, in different insulation construction method, there have been a variety of quality issues, this article is intended by the problem of the three heat generated by the method of analysis to engineering quality problems play a preventive role. First, the external wall insulation External wall insulation exterior wall is the use of benzene board, insulation mortar and other insulation materials, so that the building construction methods to achieve energy-saving insulation effect.

    The construction method has convenient construction, less demanding on the building's exterior vertical, construction progress fast and so on. In recent years, the project is also often used. However, within the external walls of insulation caused by quality problems follow. External wall deck bench backrest heights insulation is an obvious flaw: the presence of cold structure (hot) bridge so that the local temperature difference is too large to produce condensation.

    Since the inner insulation protected position only in the building interior and the inside of the beams, interior and exterior wall portion of the plate corresponding unprotected insulation materials, therefore, in this part of the formation of cold (hot) bridge, winter indoor wall temperature and indoor corner (with and without insulation wall insulation board at the angle) temperature difference of about 10 ℃, the indoor temperature and the difference may reach more than 15 ℃, once the indoor humidity conditions are suitable, where condensation can form .
