Rockwool FirePro CB Ablative Coating - 5L

ROCKWOOL FirePro® CB Coating is a water-based, ablative sealant specifically engineered to reinstate the fire resistance of FirePro® CB50 and CB60 batts where the original factory coating has been cut or damaged during installation. Designed for professional fire stopping contractors, this coating ensures that cut edges and service penetrations maintain the same high-performance ablative barrier as the original batt, restoring the system's integrity against fire and smoke passage.

The primary value of FirePro® CB Coating is its ability to ensure a compliant "made good" installation on-site. When ablative batts are cut to fit apertures, the mineral wool core is exposed, creating a potential weak point in the fire compartment line. By applying this coating to all cut surfaces, you effectively reseal the batt, ensuring the installation meets the rigorous requirements of EN 1366-3:2021+A1:2024 for up to 120 minutes of fire resistance (EI 120). This step is critical for passing visual inspections and ensuring the complete fire stopping system performs as tested.

Beyond compliance, the coating offers practical benefits for the installer. Its water-based formulation allows for quick, easy application via brush or spray, and it dries to a hard-wearing white finish that matches the pre-coated batts for a clean, professional handover. It is also formulated to support modern green building standards, carrying exemplary criteria for VOC emissions under BREEAM, LEED, and AgBB schemes, making it safe for use in enclosed working environments.
