3M Fire Barrier Sealant FD 150+


3M™ Fire Barrier Sealant FD 150+

Ready-to-use, gun-grade latex-based elastomeric sealant that cures upon exposure to the atmosphere to form a monolithic flexible firestop seal. When properly installed, this product provides up to 4-hour fire protection in tested and listed systems. Firestops construction joints and through penetrations. Available in blue, red or limestone, no mixing required, 19% movement capability.

When properly installed, sealant helps prevent the spread of fire, smoke and noxious gas. Remains elastomeric (compression/extension capability of ± 19%) and exhibits excellent adhesion to a full range of construction substrates. In addition, this product acts as an acoustic barrier by minimizing noise transfer (STC-Rating of 56 when tested in a STC 56-rated wall assembly), helps create a smoke seal for systems requiring the optional L-Rating, meets the intent of LEED® VOC environmental regulations, meets International Building Code (IBC) and other key life safety building code requirements.

  • Firestops construction joints including: bottom-of-wall, head-of-wall and wall-to-wall. Typical through penetrations firestopped include: metallic pipe, non-metallic pipe (excluding CPVC), insulated pipe, conduit, power and communication cables, combos, insulated pipe and HVAC duct penetrations.
