Multimastic FB1 are firestop boards made of a high-density rock wool core, treated with Multimastic C firestop coating on one side. Multimastic FB firestop boards make it possible to seal off larger openings, creating a fire-resistant and smoke-proof seal to adjacent rooms. Multimastic FB firestop boards form part of the Mulcol® Penetration Seal System. Multimastic FB firestop boards can also be used in combination with the Multimastic SP firestop mastic and Multimastic C firestop coating.
