PRODUCT CHARACTERISTICS

O-METALL^® fire protection panels for wall acoustics with „visible fixing“ (SB) are particularly suitable when high demands are made in regards to the sound insulation and evtl. to fire protection. Depending on the use, the size or the location of the building specific sound insulation requirements will maybe have to be observed and this will make it necessary to go for O-METALL^® acoustic wall panels. For technical reasons, the panel joint and the effective width may vary depending on the production line and core thickness in question.
