A separation layer / separation layer is understood to be layers for the permanent separation of components or building materials from each other, which are intended to prevent a harmful interaction.
Depending on their function and requirements, separation layers / separation layers can be made of different materials, e.g. plastic films, bitumen with or without inserts or laminations. (copper or aluminum foils) Separating layers / separating layers are mainly used for heavily stressed roof waterproofing (e.g. walkable and drivable flat roofs) or for screed surfaces.
Separating layers are usually carried out in two layers (especially in the case of screed).
Separating layers can consist of various materials such as polyethylene film, raw glass fleece or paper impregnated with plastic and bitumen.
