Our Firestop Panels are manufactured by spraying high-density rockwool with a fire-rated ablative coating. The coated batts are simply cut and friction fitted between the services and the edges of the structure. The fire rated coating is used as an adhesive to bond sections of batt together into a barrier and to the surrounding structure. All joins in the batt are pointed in with FirePro Acoustic intumescent Selant to form a monolithic layer. The ablative coated batt comes in 6 pieces per pack. *Plastic pipework would be needed to be sleeved with the FirePro Firestop Pipe Collars prior to installation of the FirePro Ablative Coated Batt. These must be mechanically fixed with steel angles, minimum 30mm x 30 mm x 1.6mm, or similar to the surrounding substrate.
