In such a series of energy conservation policies, regulations, standards and mandatory provisions under the guidance of Chinas energy-saving housing constru

However, Chinas current level of building energy conservation, but also much lower

Cold in the north building heating energy consumption accounts for the local society more than 20% of energy consumption, and the vast majorit

Therefore, the construction of this century, Chinas energy-saving construction is an important topic. In the construction of the external structure for the heat loss larger, exte

Therefore, the reform and building wall wall is the development of energy-saving technologies building energy-saving technology one of the most important part of the external wall insulation technology and the development of energy-savi

Exterior Insulation compared with the

A further approach is the use of a dedicated fixed-absorbent will be difficult various insulation board fixed the outer walls, and then aluminium, natural stone, stained glass, and other pre-production plug in the keel, the direct formatio

This plug-in insulation installation time-consuming, difficult construction and construction-led occupation period, the main question can only after acceptance construction.

But in the winter construction, the role of polystyrene insulation Banqi can reduce the external envelope insulation measures. But we should pay attention to pouring concrete uniform, continuous casting, otherwise con

And double steel mesh, compared to one-sided steel mesh technology with the cancellation of the inner steel mesh and installation of insulation board before the board lateral plastering, saving time and materials. Its cost can be reduced by 10 percent. However, the two approaches are used
