Single-Layer Firestop Batt Wall with 90 Minutes Integrity & 60 Minutes Insulation

The FIREFLY® FB180 Ablative Batt Wall System – 60mm is a high-performance, non-load-bearing fire protection solution designed for compartmentation in lofts, roof voids, and restricted-access zones.

Ideal for timber-framed or double-layer plasterboard constructions, the batt is friction-fitted between 90 x 38mm C16 softwood studs or joists without additional tracking.
