| Outline of Final Research Achievements |
In this research works, firstly, we try to develop the slim and translucent vacuum insulation panel (VIP) in order to improve the insulation performance at the part of window. The design method that can maintain the vacuum layer and obtain the satisfying insulation performance and transparency was established. Also, the five core materials for VIPs with transparency were selected and the VIPs were trial produced by using the core materials. Then the insulation performance and transparency were evaluated.
With regard to applying VIPs to retrofit insulation for existing buildings, the method in which the VIPs with slim and light weight are directly posted on the wall and ceiling has been suggested. Then, the reduction effect of quantity of work for retrofitting building insulation were demonstrated in the field. In addition, it was shown that the thermal bridge generated at gaps among VIPs could be reduced by applying the multilayer VIPs.
