Flexible fire resistant acoustic mastic.

Intumescent Acoustic Mastic FiAM

fischer FiAM is a one part water based acrylic emulsion that can provide up to 5 hours fire resistance when used in construction joints and services in both vertical and horizontal applications. When exposed to fire, it reacts to form a highly insulative char that slows down heat transfer, and provides a barrier to fire seal. Tested to BS EN1366-3 & 4, UL 2079 and BS476-20 the FiAM is also ETA appoved and CE Marked. Formulated to be halogen and solvent free the FiAM exhibits excellent slump characteristics and has been designed to maintain the sound reduction index of a structure.

Functionality

FiAM is a one-part water-based acrylic emulsion.
It has a fire resistance of up to 5 hours when used in construction joints and services in both vertical and horizontal applications.
When exposed to fire, it reacts to form a highly insulative char that slows down heat transfer and provides a barrier to fire.
It is suitably compatible in a variety of materials, and is utilised within the FCPS which is designed to seal large openings in fire rated floors and walls.
