3M Fire Barrier Composite Sheet CS-195+, 36 in x 36 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 for safety. This exact model from 3M combines multiple materials into one sheet to slow fire, smoke, and toxic gas spread effectively.

Its composite design includes steel, intumescent material, wire mesh, and aluminum foil, making it easy to install and dependable for firestopping needs. The CS-195+ model is suited for both new and retrofit installations.

Flexible Sheet Size Format

Each sheet measures 36 in x 36 in, providing a versatile size that can be cut and formed to fit nearly any opening. This dimension allows installers to customize firestopping solutions without extra mixing or complex preparation.

The 36-inch square format is ideal for larger penetrations like cable trays and conduit, ensuring a secure fire barrier that fits a wide range of applications while maintaining ease of handling.

Effective Four-Component System

The CS-195+ uses a four-component intumescent system that expands under heat to seal openings tightly. This system includes 30-gauge steel, intumescent material, wire mesh, and aluminum foil, all bonded together for maximum protection.

This combination creates a hard char that blocks flame spread, smoke, and toxic gases, making it suitable for horizontal and vertical cable tray runs and other critical firestop applications.

Packaged One Case Convenience

The product comes in a pack of 1 case, simplifying ordering and inventory management. This packaging ensures you get a full sheet ready for immediate use without extra assembly or components.

Having the CS-195+ in a single case supports efficient project planning and reduces waste, especially when working on fire-rated walls and floors requiring precise firestop materials.

Long-Lasting Fire Protection

This composite sheet is firestop tested for up to 4 hours according to ASTM E 814 (UL 1479), providing dependable fire resistance. The 3M CS-195+ helps maintain safety standards in demanding environments.

Its thermal conductivity also helps reduce heat build-up, which can protect equipment and minimize cable derating issues, making it a practical choice for fire-resistive and smoke seal applications.
