The 3M™ Ultra GS Wrap Strip GS-40 is an intumescent firestop wrap. This flexible wrap makes installation easy, allowing you to simply roll out and cut as much material as required to wrap around the penetrant.The 3M Ultra GS Wrap Strip works with most non-metallic and metallic insulated penetrants. It can be used for in-hole firestop installations or in conjunction with 3M Fire Barrier RC-1 Restricting Collars. When the wrap is installed in-hole in conjunction with a 3M Fire Barrier Sealant or Moldable Putty+, it also provides a cold smoke seal, which helps prevent the spread of toxic gases and other combustion by-products even before heat initiates the intumescent process.
