Study on the thermal property of a new external wall insulation system

According to current quality defects of external heat insulating system, a new external wall insulation system was designed by making full use of air´s heat insulation performance. This paper makes a comparative analysis of it and the other exterior wall external insulation systems recommended in the existing national standards (06J908-1), and conducts feasible studies from the evaluation parameters of energy-saving and thermal performance: heat transfer coefficient K indicators, energy consumption rates and economic indicators. It is proved that the new system´s indicators are better than other similar existing energy-saving systems in the market of the building energy-saving insulation design. It can greatly improve the energy-saving insulation efficiency of external walls; reduce production cost and construction refuse as well. Furthermore, the paper provides theory basis for the promotion of it in both Henan Province and other areas with similar weather conditions.
