Fire Rated Acrylic


Headway Chemicals offer Pyrocoustic manufactured by FSi Ltd in the UK.

Pyrocoustic is a one part intumescent acrylic sealant tested to BSEN 1366-4 & BS476. It is designed to resist both the passage of fire (up to 5 hours) and sound (mean sound reduction of 48dB).

The sealant will intumesce and form a char that produces a smoke seal when exposed to the heat of a fire.

In normal use it will maintain the sound reduction index of a structure.
