3M Fire Block FB 136 is ideal for use in residential construction in areas that require sealing to maintain the integrity of a fireblock. 3M FB 136 can be easily applied with a standard caulking gun, pneumatic pumping equipment or simply a putty knife and/or trowel. It adheres to virtually any material, including wood, masonry, metal and plastic. It is gray in color and applies like conventional caulk.
This fireblocking material meets all IBC, IMC, IRC, IRMC, NFPA, IFGC, IFC and ASTM E136 requirements for fireblocking in residential and combustible construction. Properly installed and cured, Fire Block FB 136
forms a solid, permanent, non-combustible, non-sag barrier that helps prevent the spread of drafts, fire, smoke and noxious gases.
