environmental protection requirements

[hhmee]

Now, with the saving of energy and environmental protection requirements continue to increase, insulation technology to maintain the structure of the building is also increasingly strengthened, especially in wall insulation technology has made great progress, and become an important building energy-saving technologies. External wall insulation in the building often used mainly within insulation, insulation, insulation and other internal and external mixing method, however, at different heating methods in the construction process, there have been a wide best way to cover your concrete steps variety of quality issues, this article is intended by the above Three problems generated by thermal analysis method, and thus the quality of the project play a preventive role. Within the external walls of insulation External wall insulation is the inside of the exterior walls of benzene boards, thermal insulation and other insulation materials, so that the building construction methods to achieve the effect of energy-saving insulation.

This construction method is to facilitate the construction, less demanding on the building's exterior vertical degrees, the advantages of quick construction progress. In recent years, the project is also often used. However, within the external walls of insulation brings quality problem has cropped up. External wall insulation is an obvious flaw: the presence of cold structure (hot) bridge so that the local temperature difference is too large to produce condensation. Due to the location within the insulation protection only in the construction of interior walls and the inside of beams, interior and exterior portion of the plate corresponding to the unprotected insulation materials, and therefore in this section is formed cold (hot) bridge, winter indoor wall temperature and indoor corner (with and without insulation board insulation wall angle at) temperature difference of about 10 ℃, the temperature difference may reach above and indoor 15 ℃, once the indoor humidity conditions are suitable, condensation can form here .

The impregnated dewdrop or freeze-thaw and could easily lead to insulation wall mildew and cracking. In addition, winter heating and summer cooling of buildings, the indoor temperature with diurnal and seasonal variation margin is generally small (about 10 ℃), this linear deformation caused by temperature changes and volume changes in interior walls and floor of the building is not Big. However, the magnitude of the temperature change effect walls and roof outdoor temperature and solar radiation heat caused by larger. When the outdoor temperature is composite decking price in singapore lower than room temperature, wall contraction amplitude than the rate in the insulation system fast, when the outdoor temperature is higher than the room temperature, wall expanded faster than the inner insulation system, which makes repeated deformation within the insulation system is always in a precarious basis on the wall, and in this role is not only a distortion stress repeatedly facades vulnerable to damage caused by thermal stress are also easily within the insulation system hollowing cracking.
