Verified by manufacturer 28 days ago
Mineral fibre ablative batt for horizontal use with timber, plasterboard and FIREFLY® barrier.
Application
- The FIREFLY® FB180 Ablative Batt Floor System can be installed above existing ceilings and 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 and plaster ceilings can be left undisturbed.
Description
FIREFLY® FB180 Ablative Batt – 60mm Floor System provides a single layer EI60:E90 fire-rated compartmentation that can be installed above ceilings between existing joists, minimising disruption.
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 density of 180 kg/m³ with a rigidity that makes it suitable for friction fitting.
Batt is cut to size to friction fit between timber (minimum 90 x 38 mm C16 softwood) that must additionally be treated with FIREFLY® Ablative Coating to maintain the fire rating of the batt – EI60:E90.
FIREFLY® FB180 Ablative Batt Floor System is tested with expected penetrations such as soil pipes, metal pipes with lagging, cable trays, cables and timber. See Installation
Drawings/Manual for full details. A complementary FIREFLY® FB180 Ablative Batt 60mm Wall System is also available.
