3M Fire Barrier Composite Sheet CS-195+, 36 in x 41 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

Trusted 3M Firestop Model

The 3M Fire Barrier Composite Sheet CS-195+ offers reliable fire protection with a tested system designed by 3M. This model combines multiple materials into one sheet, making it a trusted choice for firestopping needs.

Its composite design includes steel, intumescent material, wire mesh, and aluminum foil, ensuring effective fire resistance and ease of installation for various applications.

Flexible Sheet Size Format

This product comes in a 36 in x 41 in sheet format, allowing installers to cut and form it to fit nearly any size opening. The sheet’s flexibility makes it ideal for custom firestop solutions.

Because it can be shaped easily with common trade tools, it suits a wide range of penetrations such as cable trays and conduits, adapting to different project requirements.

Durable Composite Sheet Technology

The CS-195+ features a four-component intumescent system bonded to 30-gauge steel, reinforced with wire mesh and aluminum foil. This combination creates a hard char that seals penetrations tightly.

This durable composite sheet not only blocks fire and smoke but also helps reduce heat build-up, protecting cables and equipment from damage and derating issues.

Fire Resistance Up To

Tested in accordance with ASTM E 814 (UL 1479), this fire barrier composite sheet provides up to 4 hours of fire protection. This rating ensures safety and compliance in fire-rated walls and floors.

Its firestop capabilities make it suitable for intermittent fire breaks in horizontal and vertical cable tray runs, enhancing overall building safety and code adherence.

Convenient Pack Count

Supplied as 1 sheet per case, this packaging allows for easy handling and inventory management on job sites. The single-sheet case format supports both new installations and retrofit projects.

Having one sheet per case simplifies ordering and storage, making it straightforward to plan for firestop needs without excess material or waste.
