The aim of the work – to determine the effects of climate change to ETICS exploitation performance and durability. The service life of this ETICS depends on its resistance to climate impacts. System is affected by rainfall, wind pressure, the outside air temperature changes, solar thermal and ultraviolet and firmament long wave radiation during its service life. The composed prediction model of ETICS service life includes irrigation, refrigeration, heating and UV radiation effects, which simulate the ageing of one natural year. Determined, for the first year of operation of the system UV radiation damages render surfaces covering polymer films but at the same time during carbonization process formed the operational structure of the render surface. Consistent Heat – Rain – Cold cyclic impact better complies with the conditions of wet and cold climate than currently applied Heat – Rain and Heat – Cold cyclic impacts. According to the analysis data of Lithuanian climate and render surface structure the suitability of the created model for predicting of the durability of systems with a variety of renders is proved after comparison of the research period with the used climate data in the model and after receiving of similar degradation results of samples surfaces after natural and artificial ageing. Summarizing the experimental results prepared the adjustment recommendation for ETAG 004 test procedures.
