Protecta FR Board

Protecta® FR Board is a high-density stone wool board coated on both sides with Protecta® FR Coating, designed to prevent the spread of fire, smoke, and hot gases through openings in fire-rated walls and floors - especially those accommodating multiple building services. Assessed to AS1530.4-2014 and AS4072.1-2005, and acoustically rated to STC 55, it delivers outstanding fire, insulation, acoustic, and smoke-sealing performance. The FR Coating significantly reduces the board’s permeability, limiting hot gas transmission and minimising heat transfer to the unexposed side. Used in conjunction with Protecta® FR Acrylic, it forms a complete and highly reliable firestopping system. FR Board is quick to install, easy to retrofit, and compatible with a wide range of Protecta systems.
