Protecta FR Board is designed to prevent the spread of fire and smoke through openings in fire rated walls and floors where openings are formed to allow the installation of multiple building services. FR Board will also maintain the acoustic designed performance in fire rated walls and floors.
FR Board consists of a high density, stone wool core which is over-coated with Protecta FR Coating. The top coating provides additional protection by significantly reducing the permeability of the stone woo core and prevents the passage of hot gases, thus reducing the temperature rise on the unexposed side and reducing heat conduction through the building services.
FR Board is available with top coating on one or two sides, selected on the basis of installation considerations and fire resistance. On site, FR Board must be used together with Protecta FR Acrylic for sealing around building services and the surrounding construction.
