3M Fire Barrier Composite Sheet CS-195+, 28 in x 52 in, 1/case

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

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 30-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.

Firestopping in Nearly Any Size and Shape
For larger openings and penetrations where putties and strips alone aren’t enough, our 3M™ Fire Barrier Composite Sheet CS-195+ is a one-part firestop system that installers can cut and form to exact sizes – no mixing or damming required. These sheets are easily installed using common tools and fasteners. Ideal for firestopping penetrations such as cable trays and conduit, the sheets feature intumescent material bonded to 28-gauge galvanized steel, reinforced on its facing side with hexagonal wire mesh and covered in aluminum foil. This combination of organic/inorganic materials makes these composite sheets a reliable firestop in tested and listed systems, new and retrofit. These materials also make an excellent thermal conductor, helping to dispel built-up radiant heat to preserve process and control equipment and help minimize cable derating concerns.

Recommended Applications

• 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+

Fully Tested and Approved
3M™ Fire Barrier Composite Sheet CS-195+ is firestop tested up to 4 hours in accordance with ASTM E 814 (UL 1479).

The Science of Better Fire Protection from 3M
