Abstract: The heat-conducting property of OSB wallboard was evaluated with finite difference method and intergal transformation method and compared with the traditional construction brick wall. It was indicated that the indoor temperature was determined by the materials and structure of the wall. The wall composed by OSB and glass wool had steady heat\|conducting property. It had better property of withstanding the difference of the outdoor environment than the brick wall even it's thickness was half of the brick wall. In addition, light wood composites like OSB was benefit to control the indoor temperature of the large place with air conditioner inside.
