NOFISOL® Seal S 45/50
NOFISOL® Seal S 45/50 is composed of stonewool and is completely sealed with a thin, black acoustic open PE film. The acoustic black inlay board is applied above framework, lamellar, open lath and metal ceilings, where high acoustic and fire protection requirements are required. The board is not self-supporting and therefore not suitable for use in a profile system without supporting sub-structure.
