| Abstract: | The two heat insulating ways that are outside heat insulating and inside heat insulating were compared.Wall temperature distribution and wall inside surface temperature were analyzed.Based on the above,the advantage and disadvantage of the two heat insulating ways were analyzed.The result shows that the outside heat insulating way is better than the inside heat insulating way in some ways.To use the way of outside heat insulating,room comfort was enhanced and wall crazing was reduced.The influence of thermal bridges on heat insulating was eliminated effectively and energy cost was also reduced. |

| Keywords: | outside heat insulating way inside heat insulating way temperature of inside surface temperature distribution thermal bridges |
