PRODUCT CHARACTERISTICS

The O-METALL^® fire protection roof acoustics is especially required where strict sound insulation regulations have to be observed, here especially for protecting the collaborators. Thanks to the inner shell with acoustic perforations and the insulation core made of mineral wool, high sound insulation values can be achieved without any problems.
