3M™ Fire block foam FB-foam is a ready-to-use foam fireblock designed to help prevent the spread of flames and smoke in residential type V and commercial non-rated construction. This product is intended to resist the free passage of flame and the by-products of combustion within the concealed space of a floor, ceiling or wall cavity by restricting the movement of air, fire and smoke. Also acts as a draftstop to restrict air infiltration and movement. Meets current fireblocking sealant requirements of the International Building Code (IBC) and International Residential Code (IRC), and state and local codes based on the IBC and IRC. 3M™ Fire Block Foam FB-Foam is recognized as a requirement to the methods prescribed by IBC and/or IRC codes for maintaining the integrity of penetrations of fireblocking and for draftstopping. Tested as a type V commercial and residential fireblock for non-rated construction. This product is used to help seal, fill, insulate and bond. Also acts as a draftstop to restrict air infiltration. This ready-to-use product expands to more effectively seal penetrations than traditional products that meet the modified ASTM E 814. Not to be used as a firestop in commercial construction.
