Firestop Material for a Range of ApplicationsEngineered as a wrappable firestop for applications including blank penetrations, large openings and even plastic and other non-metallic pipe penetration systems, 3M Fire Barrier Wrap Strips FS-195+ are fire-rated up to 4 hours in tested and listed systems and meets ASTM E814 (UL 1479) performance standards. Intumescent material expands when heated to deliver excellent thermal insulation, as well as provide an effective firestop for non-metallic penetrants.Recommended Applications Plastic pipe and conduit penetrations up to 10 diameter Metal pipe penetrations Insulated pipe penetrations Blank penetrations Bus ducts Cable trays and bundles In conjunction with 3M Fire Barrier Composite Sheet CS-195+ for large openings Use with 3M Fire Barrier RC-1 Restricting Collar3M Fire Barrier Wrap Strips FS-195+ can be installed into a wide range of applications because of its convenient wrappable strip construction the flexible, firestop material comes in strips which can be quickly and easily wrapped around the penetration. Installers simply apply the strip, cut it with common tools, secure it in place with a 3M Fire Barrier RC-1 Restricting Collar, steel tie wire and/or 3M Composite Sheet CS-195+ and seal it with materials such as 3M Fire Barrier Sealant CP 25WB+ or Moldable Putty. It is designed for excellent weatherability against temperature and humidity, and is re-enterable to save added time and material costs after installation.The Science of Better Fire Protection from 3MSince 1925 when a 3M lab assistant invented masking tape, 3M has been applying science to life developing adhesive products and technologies that help entire industries and individual businesses worldwide. The work that began with a single 3M engineer now spans decades and generations. And all of it goes into each 3M adhesive, sealants and protective coatings including 3M Fire Barrier Wrap Strips FS-195+ to improve performance, and to help businesses like yours operate faster, better and more efficiently.
