FR Board

iPASSIVE FR Board is specifically designed for sealing around service penetrations in walls and floors and preventing the spread of fire and smoke through these penetrations. iPASSIVE FR Board will also maintain the acoustic performance in fire rated walls and floors.

Product Description

iPASSIVE FR Board consists of a high-density stone wool core over-coated with iPASSIVE FR Coating, an ablative fire-resistant coating and is available coated on one or 2 sides. The top coating provides additional protection by significantly reducing the permeability of the stone wool 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. 

iPASSIVE FR Board must be used together with iPASSIVE FR Acrylic for sealing around building services and the surrounding construction.
