ABSTRACT
The impact of external climate to the lifetime and quality of hydro-insulation roofing sheets is a content of many research projects. For example, research of roof pollution impact to increase of heat gains of materials, which leads to the fastest degradation or overheating of construction and also building (Ronnen Levinson) [1]. The further is research of impact of heat ageing process to the performance of PVC membranes (Paroli) [2]. The description of results of 7-year-long exposure to TPO membranes in different climate areas (Delgado) [3]. Some works are focused on fire-safety resistance and UV stability (Yang) [4]. Also results of comparison of research methods of shorten lifetime to performances of TPO membranes are published (Xing) [5]. As well as, works comparing performances of various roof membranes (Cash) [6].
