Abstract

This study investigated the thermal insulation performance of Azon and Azo-Core, two materials commonly used in window frames, for potential application in window shutters. A three-pronged evaluation approach was employed, utilizing the Therm 7.4 software, confidential test results, and dedicated thermal insulation testing. The simulation data indicated that both Azon and Azo-Core offered superior insulating properties compared to conventional shutter insulation materials. When incorporated into shutters, these materials achieved a first-grade sealing performance and a measured average thermal conductivity of 2.018W/m2·K. While this thermal conductivity value surpasses the standard requirements of 1.5W/m2·K for central regions and 1.8W/m2·K for southern regions in Korea, it falls within the acceptable limit of 2.2W/m2·K established for the Jeju region. Based on these findings, Azo-Core, warranting further dedicated research, presents itself as a promising candidate for shutter insulation material, particularly in applications targeting the Jeju region.

본 연구는 창호에 사용되고 있는 Azon과 Azo-Core를 셔터에 활용하여 단열성능을 확보하고자 Therm 7.4 프로그램과 기밀, 단열성 시험을 통해 검토하였다. 시뮬레이션 결과 Azon 및 Azo-Core는 기존의 단열재에 비해 단열성이 우수했으며 셔터에 적용 시 1등급의 기밀성능과 평균2.018W/m2·k의 열관류율을 확인하였다. 이는 외부셔터 설치 기준 중부지방 1.5W/m2·k, 남부지방 1.8W/m2·k보다 높은 수치이지만 제주지방 2.2W/m2·k에는 적용 가능한 수치이며 Azon과 병행 적용이 아닌 Azo-Core만 적용할 수 있는 추가 연구가 검토된다면 셔터 단열재로 사용 가능성이 있다.
