Firestop Solutions

Firestop sealants and products can help stop the spread of fire smoke and toxic fumes.

Billions of dollars in annual property damages and thousands of injuries and fatalities occur annually due to structure fires. However, those catastrophes can be significantly reduced with improved firestop systems specification and installation awareness among architects, engineers, contractors, code inspectors and builders.

Close enough is not good enough: A demonstration of Proper vs Improper Firestopping

This video collaboration from UL and IFC illustrates the importance of proper firestop selection and installation. Installers, designers, inspectors, manufacturers and facility owners all play a critical role in ensuring compliance with fire life safety.

IFC’s mission is to promote the technology of fire and smoke containment in building construction through research, education and development of safety standards and code provisions. –

Firestop Sealant Products

  • 3M Fire Barrier Sealant IC 15 WB+

    Establish a Strong Firestop Barrier
    Designed to prevent the spread of fire, smoke and noxious gas, 3M™ Fire Barrier Sealant IC 15WB+ is a one-part, gun-grade, latex-based, intumescent firestop sealant. This firestop sealant provides up to 3-hour fire protection in accordance with ASTM E 814 (UL 1479) and CAN/ULC S115. In addition, this product is fire resistance tested for static construction joint systems in accordance with ASTM E 1966 (UL 2079). This sealant has been formulated to form a monolithic firestop seal that also helps minimize sound transfer, acting as a barrier to airborne sound transmission (STC-Rating of 54 when tested in a STC 54-rated wall assembly).

  • 3M Fire Barrier FD 150+ Sealant

    Tried and Tested Fire Protection
    Ready-to-use, 3M™ Fire Barrier Sealant FD 150+ is a latex-based elastomeric sealant. This gun-grade sealant cures when dispensed to form a monolithic flexible firestop seal and, when properly installed, this product provides up to 4-hour fire protection in tested and listed systems. We formulated this sealant to help prevent the spread of fire, smoke and noxious gas and firestop joints and through penetrations through floor slabs, walls and other fire-rated building partitions and assemblies. This firestop sealant offers a continuous seal with ± 19% movement capability for construction joints and typical pipe movement and exhibits excellent adhesion to a full range of construction substrates.

  • 3M Fire Barrier CP-25WB+

    Dependable and Easy-to-Use Firestop Sealant
    Tough and ready-to-use, 3M™ Fire Barrier Sealant CP 25WB+ is a high-performance, one-component, latex-based, intumescent sealant that dries to form a monolithic firestop seal. This sealant also acts as a barrier to airborne sound transmission. As penetrants are exposed to fire, the unique intumescent property of this material allows 3M™ Fire Barrier Sealant CP 25WB+ to expand and help maintain a firestop penetration seal for up to 4 hours. This sealant is designed to help control the spread of fire, smoke and noxious gases before, during and after exposure to a fire when installed in accordance with a listed through-penetration or fire-resistive joint assembly system (STC-Rating of 54 when tested in a STC 54-rated wall assembly).
