3M Fire and Water Barrier Tape FWBT4, 4 in x 75 ft, 12 Each/Case

• Acts as an immediate barrier to water leakage
• Broad temperature range when applying
• High tack adhesive sticks to many common building materials
• Provides fire, water and smoke protection in construction and perimeter joints
• Works as acoustic barrier by minimizing noise transfer

3M Fire and Water Barrier Tape is an elastomeric fire, water, smoke and sound tape. When installed properly it can act as a barrier to water leakage and airborne sound transmission, while helping to control the transmission of fire, heat and smoke.

3M Fire and Water Barrier Tape can provide up to 4-hours of fire protection in construction joints per ASTM E 1966 (UL 2079), 3-hour fire protection in perimeter joints per ASTM E 2307 and 2-hour fire protection in through-penetration applications per ASTM E 814 (UL 1479).

Applications

• Fire protection in construction and perimeter joints
• Fire protection in through-penetration applications
• Acoustic barrier
• Barrier to water leakage

This elastic material maintains performance with up to +/- 50% movement capabilities. It has a high tack adhesive that sticks to most common building materials and exceeds the AAMA 711 minimum for adhesion in peel. In addition, it can be installed in temperatures as low as 0°F (18°C) and as high as 120°F (49°C). Adding to its versatility is a unique adhesive that bonds to damp surfaces. This product acts as an acoustic barrier by minimizing noise transfer (STC-Rating of 54 when tested in a STC 54-rated wall assembly), meets the intent of LEED VOC environmental guidelines and also acts as an immediate barrier to water leakage passing the ASTM D 6904 rain resistance test. Our 3M Fire and Water Barrier Tape complies with the current requirements of the International Building Code (IBC). NFPA 5000 and NFPA 101.

3M Fire Water Barrier

The 3M Fire and Water Barrier Tape FWBT4 is designed to provide reliable protection against fire, water, and smoke. This elastomeric tape acts as an immediate barrier to water leakage, helping to maintain building integrity in critical areas.

Its fire-resistant properties make it suitable for construction and perimeter joints, offering up to 4 hours of fire protection per ASTM E 1966. The model FWBT4 ensures dependable performance in demanding environments.

Four Inch Tape Width

This product features a 4 inch width, making it easy to apply over joints and seams where protection is needed. The size allows for effective coverage while maintaining flexibility for various construction applications.

The 4 inch dimension also supports its role as an acoustic barrier, minimizing noise transfer in walls and partitions. This width balances coverage and ease of handling during installation.

Seventy Five Feet Length

Each roll of the FWBT4 tape measures 75 feet in length, providing ample material for multiple applications. This length supports continuous sealing over long joints without frequent splicing or overlaps.

Having 75 feet per roll reduces installation time and waste. It’s ideal for projects requiring consistent fire and water protection across extended surfaces.

Twelve Rolls Per Case

The tape is packaged with 12 rolls per case, offering a convenient bulk supply for contractors and builders. This pack size helps ensure enough material is on hand for larger projects or multiple sites.

Buying in cases of 12 also simplifies inventory management and reduces the need for frequent reordering. It supports efficient workflow on construction jobs.

High Tack Adhesive Performance

The FWBT4 tape uses a high tack adhesive that sticks firmly to many common building materials. This strong adhesion helps maintain the barrier’s effectiveness even under movement or temperature changes.

Its adhesive works well across a broad temperature range, from 0°F to 120°F, and can bond to damp surfaces. This versatility makes it suitable for various climates and installation conditions.
