Acoustic insulation plate

摘要

The acoustic insulation plate, esp. for buildings, has a profiled and/or roughened structure at least at the outer surface and/or an inner grid structure. The leading side is cladded with a textile material or with a textile material which gives a profile. A layer of mortar, for surface profiling, contains polybutadiene as an adhesive. The support mould has an inner layer of silicon. The plate is of foamed polystyrene. The plate can be mounted with an additional non-woven material of glass fibres.
