Fire Batts and Mastic - Fire Protection Systems from Dufaylite

The Dufaylite  Fire Batts and Mastic system provides up to 4 hours passive fire resistance to BS 476 Part 20 in sealing service penetrations in walls and floors.

  • The Dufaylite Fire Batts have a mineral fibre core coated both sides with Dufaylite fire resistant mastic
  • The Fire Batt mineral fibre core is manufactured using a process that maintains the integrity of the board during installation to minimise wastage.
  • The Dufaylite Mastic is a high performance, flexible, water based acrylic mastic. It is ablative in nature, which means that, in fire conditions, Dufaylite Mastic changes into a tough and highly resistant ceramic coating. Dufaylite Mastic has low smoke and toxicity properties and it is fibre and halogen free.
