Abstract

Insulation of rooftop is one of the major performance to energy-saving construction. Further, waterproofing performance is also important. For such a reason, it is need to develop waterproofing method containing thermal insulation property. This study was wanted to evaluate thermal insulation performance about the composite waterproofing method of thermal supplement type that is developed recently. As a result of waterproofing performance test, every test item was showed over the performance standards of KS (Korean (Industrial) Standards). And the result of thermal insulation performance test, the highest temperature in the styrofoam box was $25.91^{\circ}C$, the bubble sheet box was $17.28^{\circ}C$, the insulation sheet box was $15.47^{\circ}C$ and the waterproofing sheet box of thermal supplement type was $24.11^{\circ}C$. In observations of thermal bridges of sheet's joint, thermal bridges was not identified at the sheet's joint. As a result, composite waterproofing method of thermal supplement type is interpreted to have thermal insulation performance.

건설구조물 상부의 단열은 에너지 절약 건설구조물에 있어서 중요한 요건 중 하나이다. 건설구조물 최상부는 단열성뿐만 아니라 방수성능도 중요하다. 이와 같은 이유로 단열성을 확보한 방수공법의 개발이 요구된다. 본 연구에서는 최근 일정 단열성능을 확보한 단열 보완형의 복합방수공법이 개발되어 해당 공법에 대한 단열성능을 평가하고자 하였다. 방수성 시험결과, 모든 시험체는 KS 표준 이상의 성능을 보여주었다. 단열성 시험결과, 스티로폼 박스가 가장 높은 온도인 $25.91^{\circ}C$, 버블시트 박스가 $17.28^{\circ}C$, 단열시트 박스가 $15.47^{\circ}C$, 단열보완형 방수시트가 $24.11^{\circ}C$로 확인되었다. 시트 접합부의 열교현상을 관찰한 결과 열교현상은 발생하지 않았다. 단열보완형 복합방수공법은 단열성능을 확보하고 있는 것으로 판단된다.
