Abstract

The pros and cons of green building thermal insulation materials and systems have been reviewed from traditional thermal insulation materials such as mineral wool and polyurethane to new thermal insulation materials like VIP and aerogel and future insulating VIM and DIM. VIPs and aerogels with very low thermal conductivity can use for green buildings to significantly increase residential area by reducing energy consumption. Aerogels can be produced as not only opaque and but also translucent forms, thus enabling a wide range of possible building application. For building applications, there are many properties to consider like building site adaptability and mechanical strength, fire protection, cost and environmental impact.

친환경 건축물에 사용되는 미네랄울, 폴리우레탄 등 전통적인 단열재로부터 최근에 주목받고 있는 VIP (Vacuum Insulation Panel), 에어로젤, 그리고 미래기술로 연구되고 있는 VIM (Vacuum Insulation Material), DIM (Dynamic Insulation Material) 등 단열재 및 단열 시스템의 특성과 장단점을 비교하였다. 매우 낮은 열전도율을 지닌 VIP 및 에어로젤은 기존 단열재에 비해 에너지 소모를 줄일 수 있으므로 주거면적을 크게 확대할 수 있는 장점이 있으며, 특히 에어로젤은 반투명 및 투명재질로 만들 수 있어 건물에 응용될 수 있는 가능성이 매우 크다. 단열재는 낮은 열전도율뿐만 아니라, 건설현장 응용성, 기계적강도, 내화성, 비용 및 환경영향 등을 고려하여야 하므로, 전통적인 단열재 및 최신 단열재를 활용하고 지속적으로 개선시키는 노력을 해야 할 것이다.
