FLAMEBLOCK® FRMDF & BLACK MRMDF
FlameBlock by Briggs Veneers is a fire-rated MDF substrate board engineered for projects where compliance is critical and aesthetics cannot be compromised. Designed for architects and specifiers working across commercial and high-occupancy environments, FlameBlock provides the confidence of fire-rated performance with the workability and finish quality expected of a premium MDF board.
Fire retardant through its full depth – not just at the surface – FlameBlock is certified to achieve Fire Hazard Group 2 for interior walls and ceilings in raw, painted, and veneered form. This certification applies to veneer densities up to 755kg/m³, across 12mm to 25mm thickness, in both Natural and Black.
All Briggs Veneers fire hazard group assessments are conducted in accordance with AS 5637, tested via ISO 9705 Room Burn methodology as required by the Australian National Construction Code (NCC) 2022 – giving specifiers the documentation and assurance they need at every stage of a project.
Where building codes demand more, FlameBlock delivers – without limiting your design intent.
