Multimastic FB1 and Multimastic FB2 are fire stopping boards made of a high-density rock wool core, treated with Multimastic C firestop coating on one or both sides. Multimastic FB fire stopping boards make it possible to seal off larger openings, creating a fire-resistant and smoke-proof seal to adjacent rooms.

Multimastic FB fire stopping boards form part of the Mulcol® Penetration Seal System. Multimastic FB fire stopping boards can also be used in combination with the Multimastic SP fire stopping mastic and Multimastic C firestop coating.
