The Astro PFP 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. It will also maintain the acoustic design performance in fire rated walls and floors.
The Astro PFP FR Board consists of a high density stone wool core, over-coated with Astro PFP FR Coating. The top coating provides additional protection by significantly reducing the permeability of the stone wool core and preventing the passage of hot gases, thus reducing the temperature rise on the unexposed side and reducing heat conduction through the building services.
Astro PFP FR Board is available coated on one or two sides, depending on the seal design to provide the required fire resistance. On site, Astro PFP FR Board must be used together with Astro PFP Acrylic for sealing around building services, joints and edges of the FR Board and the surrounding construction.
