3M™ Fire Barrier Composite Sheet CS-195+ is a lightweight intumescent firestop that combines four components into a single system to help slow the spread of fire, smoke and noxious gases. Sheets combine 28-gauge steel, intumescent material, wire mesh and aluminum foil and are easy to handle and install with common trade tools. They are firestop tested for up to 4 hours of fire protection.

• Four-component intumescent system is ideal for firestopping larger penetrations such as cable trays and conduit
• Forms effective intermittent fire-break within horizontal and vertical cable tray runs
• Hard char material tightly seals penetrations against flame spread, smoke and toxic gases
• Easy to install: cut, form and install using common trade tools for nearly any size
• Thermally conductive: allows unwanted heat build-up to escape, helping reduce derating issues
• Re-enterable for new or retrofit installations
• Firestop tested for up to 4 hours in accordance with ASTM E 814 (UL 1479)

• Seal penetrations through fire-rated walls and floors
• Firestop penetrations including cable trays, cable, piping and large blanks
• Multiple component installations where heat build-up and derating are concerns
• Shield conduit, HVAC ductwork, panels, valves and vital heat-sensitive process equipment
• Fire-resistive and smoke seal for any shape opening in concrete block or slabs
• Protect cable drop-outs, junction boxes and cabinets
• Intermittent firestop in horizontal and vertical cable tray runs
• In conjunction with 3M™ Fire Barrier Sealant or Moldable Putty MP+
