[摘　要]　以郑州地区市面上比较流行的几种墙体保温材料节能体系为参照，采取市场调查方式获得各种墙体保温材料节能体系的单方造价，以此建立体系热量损失与保温层厚度的关系式并计算出每种体系自身的单方造价与热量损失值平衡点，获得每种体系的最佳厚度。

[关键词]　墙体保温材料,造价,厚度

Abstract: Take Zhengzhou for example, this survey analyzes several popular energy-saving wall insulation systems on the market today in cold regions, obtains the meter cost of every energy-saving wall insulation system. At the same time, builds the relationship between the heat loss and the insulation thickness of every system, finds the balance between the meter cost and the insulation thickness, and obtains the optimum thickness of each system.

Key words: wall insulation material, cost, thickness
