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
