Mineral fibre ablative batt with bonded graphite strip for use with FIREFLY® systems.
Providing a fire-tested solution to close the void between roof membrane and tile at compartment lines, FIREFLY® Roof Cavity Closer is a specially manufactured combination of ablative batt and intumescent graphite. The bonded intumescent graphite strip will expand to fill the void to the outer tiles in the event of a fire.
The FIREFLY® Roof Cavity Closer should be friction-fitted into the void and edges “buttered” and sealed with FIREFLY® FR Intumescent Acrylic. Consult drawings on the
FIREFLY® website for full installation details for various scenarios.
