Multifunctional surface coating for e.g. wall, has two layers, where one of layers is formed from nonwoven felt comprising polyester fibers bonded together by mechanical and/or chemical connection, and layers and coating are joined by glue

摘要

The coating (1) has a layer (2) with a function of partial barrier to electromagnetic waves. The layer includes metal elements or compounds, and is formed of non-woven synthetic fibers e.g. Shielding fleece HNV 80(RTM: Metalized special-fleece). Another layer (3) is provided with a function of absorbing and/or acoustic insulation. The latter layer is formed from a nonwoven felt comprising polyester fibers bonded together by mechanical and/or chemical connection. The former layer, the latter layer and the coating are joined together by glue (4). The coating is provided in the form of a multi-layer coating.
