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.
