If it's yellow and 3M, it's UL-tested

UL listed

It's not safe to assume that because a firestop caulk is red, it has been UL-tested for your applications. 3M offers the yellow firestop caulk that has been UL-tested to ASTM E 814 for the most common applications.

3M Fire Barrier IC 15WB Caulk is an affordable firestop caulk that helps you stay on budget. Our distinctive yellow firestop caulk makes inspections easier. Plus, our fire barrier sealant provides protection around typical pipe and cable penetrations through fire-rated construction.

      Comments about 3M Fire Barrier IC 15WB Sealant - 10.1 oz Tube:

      Be thorough in researching any product for the fire rating. The tests they list for their fire rating do not include the design number used to make the test, so you don't know how long it was actually tested. Residential could be 15 minutes, commercial should be at least 30 for a smoke rated wall, 1 hour for a fire barrier, and 2 hours for a fire wall.

      Retailers need to include the design numbers, as well as the test numbers so that consumers know how to use the product and how long the design is rated for!
