FABROCK THERM 413 boards are designed to bond to the back of composite panels containing a FABROCK THERM 413 A1 non-combustible core. FABROCK THERM 413 provides additional thermal and acoustic insulation where required. The boards have one close tolerance face for bonding to the rear of the panel. The external side has a factory applied aluminium foil face. Additional foil tape can be applied to the exposed edge detail for aesthetics.
