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
Since 1925 when one of our lab assistants 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 of our adhesives, sealants, protective coatings, devices and firestop products including 3M™ Fire Barrier Composite Sheet CS-195+ to improve performance, and to help businesses like yours operate faster, better and more efficiently.

Trusted 3M Firestop Model

The 3M Fire Barrier Composite Sheet CS-195+ offers reliable fire protection with a tested system designed by 3M. This exact model combines multiple materials to slow fire, smoke, and toxic gases effectively.

Its unique four-component intumescent system is built into the CS-195+ model, making it ideal for larger penetrations like cable trays and conduit. This model is easy to cut and form for precise installation.

Flexible Size And Format

Measuring 28 in by 52 in, the sheet size allows installers to cover a wide range of openings. The format is a composite sheet that includes steel, intumescent material, wire mesh, and aluminum foil.

This format technology helps create an effective fire barrier that can be shaped to fit nearly any size or shape. The sheet’s dimensions make it practical for both new and retrofit installations.

Long-Lasting Fire Protection

The CS-195+ is firestop tested for up to 4 hours according to ASTM E 814 (UL 1479), ensuring dependable fire resistance. This duration helps protect structures and equipment during critical fire events.

Its hard char material seals penetrations tightly, preventing flame spread, smoke, and toxic gases from passing through. This level of protection is essential for safety in fire-rated walls and floors.

Convenient Pack Size

Sold as 1 sheet per case, the pack size simplifies ordering and inventory management. This single-sheet case allows installers to purchase exactly what they need for specific projects.

The pack size also supports easy handling and transport on job sites. It’s designed to fit common trade tools for quick cutting and installation without extra mixing or preparation.

Effective Heat Dissipation

The composite sheet’s materials are thermally conductive, which helps unwanted heat escape and reduces cable derating issues. This feature protects heat-sensitive equipment and maintains system performance.

By combining 30-gauge steel with aluminum foil and wire mesh, the CS-195+ balances fire resistance with heat management. This makes it suitable for installations where heat build-up is a concern.
