In this study, It has the purpose to evaluate the insulation of the curtain wall of a building on the construction from 1990 to 2011 by measuring the inside and outside surface temperature of the curtain wall. The outside frame surface(mullion bar or spandrel bar) temperature of the curtain wall is 6℃~10℃ higher than that of the surface of glasses or insulation panel of curtain wall in winter. Furthermore the outside surface of frame anchor unit is 2℃~3℃ higher than section of other frame, so it was verified lossing lots of heating.

It is very important to improve the insulation performance of curtain wall anchoring unit since it is composed of materials with high thermal conductivity, such as aluminium, steel and so on. This study aims to evaluate the heating energy performance and economical efficiency of various alternatives which are different in position and material of insulation. As results, alternative of inserting the urethane washer & pad and coating the anchoring unit with urethane foam can improve the heating energy performance and L.C.C(Life Cycle Cost) by 6.33% and 0.95%, respectively, as compared with the existing case.

This study is to evaluate the thermal insulation of the curtain wall of the buildings constructed since the 1990s to the buildings currently under construction in 2011 and to provide the basic data for repairing and reinforcing and designing the thermal insulation. To this effect, the temperature difference by part was analyzed through measuring the inside and outside surface temperature of the curtain wall of the office building, and thereafter, the conditions of the thermal insulation and the thermal bridge part were examined. The result of the study is as follows; Not only in the winter season when the temperature difference between the indoor-outdoor is over $20^{\circ}C$, but also in the summer season when there is a small temperature difference, the temperature difference between the inside and outside of the frame is $2^{\circ}C{\sim}4^{\circ}C$ equally. Under such conditions as stated above, the thermal bridge occurred, which resulted from the heat flow of the steel frame part (mullion, transom), and therefore, the reinforcement of the thermal insulation is considered to be needed.

In this study is to improve insulation performance that are the most weak insulation part of fastening unit of the curtain wall. It was produced that thought out to minimize mullion and connecting part, and evaluated performance that make a layer of insulation in the middle by using vibration-proof rubber or silicon. Vibration-proof rubber insulation is 2.6℃~4.0℃ higher and silicon insulation is 2.4℃ higher than non-insulation. Therefore the insulating layer of fastening unit is necessary.
