Mulcol FB2 Batt

Multimastic FB1 and FB2 are high-performance firestopping boards manufactured from a dense stone wool core, coated with Multimastic C firestop coating on one or both faces. Designed for sealing larger service openings, these boards provide an effective fire and smoke barrier, helping to maintain compartmentation between adjacent areas.

As part of the Mulcol® Penetration Seal System, Multimastic FB boards offer a versatile solution for a wide range of applications. They can also be used in conjunction with Multimastic SP firestopping mastic and Multimastic C coating to deliver a complete, tested fire protection system.
