FIREFLY FB180 Ablative Batt 60mm Wall System

FIREFLY® FB180 Ablative Batt – 60mm Wall System provides a single-layer EI60:E90 fire-rated compartmentation wall that can be installed free-standing or within timber or plasterboard applications.

Layers of mineral wool are combined to create a 60 mm thick board product, with an ablative coating factory-applied to both sides. The board has a weight of 180 kg/m³

with a rigidity that makes it suitable for friction fitting.

FIREFLY® FB180 Ablative Batt Wall System is tested with expected penetrations including the FIREFLY® Access Panel. See Installation Drawings/Manual for full details.

A complementary FIREFLY® FB180 Ablative Batt 60mm Floor System is also available.
