Long‑lasting exposure was simulated on a thermal insulation model based on expanded polystyrene with a mineral wool strip. The second exposure sequence caused the top layer cracking. The crack width in the barrier area exceeded 0.2 mm, suggesting a loss of watertightness. 3D scanning and inspection analysis was used for deformation assessment. It revealed deformation within the mineral wool strip. A decrease in the top layer adhesion to the thermal insulation material was reported.

Model ocieplenia na bazie ekspandowanego polistyrenu z pasem wełny mineralnej poddano długotrwałej ekspozycji. Druga sekwencja oddziaływań skutkowała pęknięciami warstwy wierzchniej. W obszarze bariery przekroczyły one szerokość 0,2 mm, co wskazuje na utratę wodoszczelności. Do oceny deformacji zastosowano skanowanie 3D z analizą inspekcyjną. Uwidoczniło ono deformację w obrębie pasa wełny mineralnej. Odnotowano zmniejszenie przyczepności warstwy wierzchniej do materiału termoizolacyjnego.
