A new method is proposed to construct the relationship between the thickness and the thermal resistance of the roof insulation layer. The numerical analysis and experiment of the relationship between the thickness and the thermal resistance of the roof insulation layer in cold regions is achieved by theoretical calculation and experiment. Firstly, the material properties and structure model of roof insulation layer in cold regions are analyzed. Then the thickness and thermal resistance of the insulation layer are analyzed. The thermal resistance detection model is presented. The experimental results show that the model can accurately analyze the relationship between the thickness and the thermal resistance of the roof insulation layer in cold regions, and can effectively achieve the optimum ratio of insulation layer thickness and thermal resistance performance.
