FIREFLY FB180 Ablative Batt – 60mm Floor System provides a single layer EI60:E90 fire-rated compartmentation that can be simply installed above ceilings between existing joists, minimising disruption.

USE AREAS

The FIREFLY FB180 Ablative Batt Floor System can be installed above existing ceilings, placed between timber joists which are treated with a suitable intumescent paint.

Commonly used in retrofit to upgrade fire compartmentation in applications such as multiple occupancy dwellings and historic buildings where existing ornate or lathe & plaster ceilings can be left undisturbed.

PENETRATIONS

FIREFLY FB180 Ablative Batt Floor System is tested with expected penetrations such as soil pipes, metal pipes with lagging, cable trays, cables, timber etc. See Installation Drawings/Manual for full details

A complementary FIREFLY FB180 Ablative Batt 60mm Wall System is also available

CONSTRUCTION

Layers of mineral wool are combined to create a 60mm thick board product, with an ablative coating factory-applied to both sides. The board has a density of 180kg/m3 with a rigidity that makes it suitable for friction fitting.

APPLICATION

Batt is cut to size to friction fit between timber (min. 90 x 38mm C16 softwood) that must additionally be treated with FIREFLY Ablative Coating to maintain the fire rating of the batt – EI60:E90
