3M Aluminum Foil Tape 425
- Highly engineered acrylic adhesive provides long term durability but removes cleanly after harsh masking applications
- Withstands exposure to flame, weathering, moisture, and UV
- Heat and light reflective tape protects surfaces and enhances lighting efficiency
- Dead soft aluminum foil backing conforms to curved and uneven surfaces
- Recognized by UL to UL 746C and Classified by UL to UL 723, Class “L” for low flammability rating
- Contains plastic core center
3M Smoke and Sound Tape
Ideal for providing a smoke and sound seal for construction
joints and through penetration applications in non-fire-rated
wall and floor assemblies, including smoke partitions and
acoustic assemblies. When installed properly, this material is
used to provide a smoke seal to mitigate the spread of smoke
and toxic gas, as well as help, reduce the transmission of sound
(refer to installation instructions — may require mineral wool
or backer rod to achieve STC ratings).
3M Fire and Barrier Tape
Ideal for sealing perimeter joints (curtain wall joints) and other construction joints as well as some through-penetration applications. When installed
properly (using mineral wool or backer rod if needed), this tape acts as a barrier to fire, water, smoke and sound.

- Up to 3-hour fire protection in perimeter joints (ASTM E2307)
- Up to 2-hour fire protection in through-penetration applications (ASTM E814/UL 1479)
- Great for water protection: meets UL Water Leakage Test, W Rating — Class 1 requirement; tested and immediately passed ASTM D 6904 Rain Resistance Test.
3M Fire Barrier Expantrol Flexible Intumescent Strip (E-FIS)
Designed to seal the air space between doors and frames and for glazing fire resistant glass to help prevent the passage of smoke and flames in the event of a fire.
- Expands when heated to seal around objects consumed by fire.
- Retards spread of toxic by-products of combustion
- Excellent flexibility, easy, cost-effective installation
- Low flame spread and smoke development
- Can be cut to fit irregular shapes
- No special tools required
- Non-flame supporting
- Low odour
