保温材料的热性能随着时间的推移而降低。在建筑物的设计阶段应考虑到这种绝缘老化，以使绝缘性能在建筑物的整个生命周期内保持在所需的范围内。本文首先对影响绝缘材料性能的各种因素进行了研究。影响纤维隔热性能的主要因素是水分、振动和微生物。塑料绝缘泡沫的主要因素是环境温度，它加速了发泡剂的扩散。其次，对销售的新绝缘和报废的旧绝缘进行了真实的性能测试，并与日本标准要求值进行了比较。部分绝缘性能低于标准值，出现性能变化。最后，根据试验数据讨论了振动对纤维绝热层性能的影响。振动试验后观察了绝缘层厚度和热阻的变化。
Thermal performance of insulation materials decreases with the passage of time. Such ageing of insulations should be considered in the design stage of buildings to keep insulation performance within the required one throughout the lifecycle of buildings. Firstly, this paper focused various factors that affect performances of insulations. The main factors for fiber insulations are moisture, vibration and microbe. The main factor for plastic insulation foams is ambient temperature that accelerates the diffusion of blowing agent. Secondly, real performances of sold new insulations and scraped old ones were measured and compared the required value by Japanese standard. Performances of some insulations were lower than standard values and performance change was detected. Finally, this paper discussed the influence of vibration on performance for fiber insulations based on the experimental data. The changes of insulation depth and thermal resistances were observed after the vibration test.
