A covering (100) suitable for protecting a core (210) of an insulation panel (200) of an external thermal insulation composite system. The covering (100) comprising a base structure (110) comprising a fibrous non-woven layer (111) and a polymer multilayer structure (120) joined to the base structure (110). The polymer multilayer structure (120) comprises a first (122) and a second (123) tie polymer layer (122), and a core layer (121) in between them. The core layer (121) is made of polymer material, is castable or extrudable, and has a specific mass of at least 1 g/m 2 . Thus, the covering (100) is gas tight at least to some extent. The covering (100) comprises a first surface (130) and an opposite second surface (140). The fibrous non-woven layer (111) comprises the first surface (130) of the covering (100), whereby a rendering (425) can be applied onto the first surface (130) of the covering (100). The second surface (140) of the covering (100) can be attached to a core (210) of a thermal insulation element (200). A thermal insulation element (200) comprising such a covering (100). A wall (400) comprising such a thermal insulation element (200). |
