As energy use in the building sector is increasing worldwide, building materials with characteristics that save energy are becoming increasingly important; in addition, there is an emerging need for high-performance insulation materials with low thermal conductivity. However, thermal insulation should consider thermal conductivity, which is the main performance parameter, in addition to the water adsorption rate, acidity, and deformation and expansion due to drying conditions. This study evaluated the main performance of 21 insulation materials used at construction sites to objectively and clearly evaluate their overall performance, including their thermal conductivity. Thermal conductivity was measured by the heat flow meter method according to ASTM C518 and ISO 8301 standards; it was also evaluated according to the drying conditions. The water absorption rate was evaluated by ISO 2896 to ensure the sustainability and long-term thermal conductivity performance of the material. Acidity was evaluated with ASTM E861 to reduce the environmental load of the buildings and soil. The results of this study reviewed an appropriate method to measure the main performance according to the type of insulation.

随着全球建筑行业能源使用量的增加，具有节能特性的建筑材料变得越来越重要。另外，对低导热率的高性能绝缘材料的需求正在出现。但是，绝热材料除了要考虑吸水率，酸度以及干燥条件引起的变形和膨胀以外，还应考虑导热系数，这是主要的性能参数。这项研究评估了建筑工地使用的21种保温材料的主要性能，从而客观，清晰地评估了它们的整体性能，包括其导热性。根据ASTM C518和ISO 8301标准通过热流量计方法测量热导率；还要根据干燥条件进行评估。通过ISO 2896评估吸水率，以确保材料的可持续性和长期导热性能。用ASTM E861评估了酸度，以减少建筑物和土壤的环境负荷。这项研究的结果回顾了一种根据绝缘类型测量主要性能的合适方法。
