3M Fire Barrier Composite Sheet CS-195+, 16 in x 28 Inch, 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 Solution

The 3M Fire Barrier Composite Sheet CS-195+ offers reliable fire protection with a tested firestop system. This product from 3M combines four components into one, providing effective resistance against fire, smoke, and toxic gases.

Designed as a composite sheet, the CS-195+ model is easy to install and cut to size, making it a practical choice for various firestopping needs. Its lightweight design simplifies handling during installation.

Precise Size And Format

This fire barrier sheet measures 16 inches by 28 inches, providing ample coverage for larger penetrations. The format combines steel, intumescent material, wire mesh, and aluminum foil into a single, easy-to-use sheet.

Its 30-gauge steel backing and hexagonal wire mesh reinforcement ensure durability and strength. The format supports firestopping for cable trays, conduit, and other penetrations requiring a solid barrier.

Four-Component Intumescent System

The CS-195+ features a four-component intumescent system that expands when exposed to heat, sealing openings effectively. This system is ideal for larger penetrations where traditional putties or strips might not suffice.

Its hard char material tightly seals against flame spread, smoke, and toxic gases, providing up to 4 hours of fire resistance as tested under ASTM E 814 (UL 1479) standards.

Packaged For Convenience

Each case contains one sheet of the 3M Fire Barrier Composite Sheet CS-195+, simplifying ordering and inventory management. This pack size suits contractors needing a reliable firestop solution without excess waste.

The single-sheet packaging also supports easy transport and storage on job sites. It’s designed for both new installations and retrofit projects where fire protection upgrades are necessary.

Versatile Installation Benefits

Installation is straightforward with common trade tools, allowing the sheet to be cut and formed to fit nearly any size opening. This flexibility makes it suitable for horizontal and vertical cable tray runs and other complex penetrations.

Additionally, the sheet’s thermal conductivity helps dissipate heat buildup, reducing cable derating concerns and protecting sensitive equipment. It’s re-enterable, supporting future modifications or maintenance.
