The FR Board is a high-performance fire and acoustic barrier used to seal large openings in fire-rated walls and floors. Designed for use around multiple building service penetrations, it helps prevent the spread of fire, smoke, and sound while maintaining structural flexibility. The board features a dense stone wool core coated with a fire-resistant barrier that limits heat transfer and hot gas movement. It is suitable for retrofits, new builds, and a wide range of constructions.
