Fire Barrier Composite Sheets

Low Price GuaranteeWhat's special about composite sheets from 3M™?

  • Intumesces (expands with heat) to form a hard char that tightly seals penetrations against flame spread, smoke and toxic fumes
  • Multiple applications...through penetration firestop, heat shield and firebreak protection
  • GSA approved Easy to install using common trade tools
  • Click for More Features

3M™ Fire Barrier CS-195+ Composite Sheet is a one-part composite system comprised of four components. The heart of the system is an organic/inorganic, fire-resistive elastomeric sheet. It is bonded on one side to a layer of 28 gauge galvanized steel. The other side is reinforced with hexagonal shaped steel-wire mesh and covered with aluminum foil. CS-195+ Composite Sheet is designed to seal larger penetrations through fire-rated walls and floors.

  • Thermally conductive...allows unwanted heat build-up to escape.
  • Non-flame supporting.
  • UL Classified.
  • Cost effective, high performance versus installed cost.
  • No mixing or damming...is clean to install.
  • Versatile: can be cut to fit irregular shapes.
  • Re-enterable.
  • Low odor.
  • Normal disposal procedures.
  • Lightweight... easy to handle, cut and form to desired shape.
  • Easy to fasten... bolt punch or drill through. Use self-tapping screws or anchor bolts.

 

CS-195+ Composite Sheet functions as an effective intermittent fire-break within horizontal and vertical cable tray runs, and is excellent for both new and retrofit construction. It is also used for shielding cable trays and conduit, HVAC ductwork and vital process equipment from radiant heat, flame spread and smoke.

The nominal 0.3 inch (7.62 mm) thick composite sheet provides up to a 4-hour fire rating. It is lightweight and can be easily installed with common trade tools.

When exposed to temperatures in excess of 250°F (121°C), the fire-resistive sheet begins to volumetrically expand and swells 8-10 times its original size, forming a high strength, hard char that retards heat transmission. This expansion process is called "intumescence."

Under normal operating conditions, CS-195+ Composite Sheet is a good thermal conductor which allows unwanted heat build-up to escape from process and control equipment and also minimizes power cable derating.

A. Product
The intumescent sheet must be capable of passing ASTM E 814 (ANSI/UL 1479) Standard Method of Fire Tests for Through-Penetration Fire Stops up to the desired fire resistance rating.

B. Engineering/Architectural
All penetrations in fire rated walls, floors, floor ceiling assemblies and designated smoke or fire barriers shall be sealed with 3M Brand Fire Barrier Products per manufacturers' installation instructions.

Exact instructions for specific applications are available upon request from 3M or your local authorized 3M Fire Protection Products Distributor. The following summarizes three representative applications:

A. Penetration firestop for blank openings (no penetration item) using 3M Fire Barrier CS-195+ Composite Sheet.

  1. Cover Sheet : A CS-195+ Composite Sheet is cut to overlap the opening by a minimum of 2 in. (50,8 mm) installed with its galvanized steel surface facing outward (exposed). The cover sheet is secured to the opening using 1/4 in. (6,35 mm) x 1-1/2 in. (38,1 mm) steel masonry fasteners with steel washers spaced 6 in. (152,4 mm) O.C.
  2. Seal: 3M Fire Barrier CP 25 WB+ Caulk, or Moldable Putty+ is used to seal the CS-195+ Composite Sheet.
    Note: All wall openings require a cover sheet of CS-195+ Composite Sheet and caulk/putty on both sides of the wall.

B. Penetration firestop for large openings with pipe using CS-195+ Composite Sheet.

  1. Cover Sheet: The opening is covered with CS-195+ Composite Sheet cut to fit snugly around pipes and to overlap the opening by a minimum of 2 in. (50,8 mm). The sheet's galvanized steel layer should face outward (exposed).
  2. The CS-195+ Composite Sheet is secured with 1/4 in. (6,35 mm) x 1-1/2 in. (38,1 mm) steel masonry fasteners with steel washers spaced 6 in. (152,4 mm) O.C.
  3. Seal: 3M Fire Barrier CP 25 WB+ Caulk and Moldable Putty+ is used to seal the CS-195+ Composite Sheet.

C. Penetration Firestop for Insulated Metal Pipe through a cement block or concrete wall.

  1. The CS-195+ Composite Sheet must be placed on both sides of the wall and overlap the edge of the opening a minimum of 2 in. (50,8 mm).
  2. Use a minimum of 1 layer of FS-195+ Wrap/Strip for a 1 in. (25,4 mm) thickness of insulation. Use a minimum of 2 layers of FS-195+ Wrap/Strip for a 2 in. (50,8 mm) thickness of insulation.
    Note: It is not necessary to remove the pipe insulation as it passes through the wall.
  3. Wrap the required number of layers of FS-195+ Wrap/Strip around the insulated pipe, foil side out. Secure the FS-195+ Wrap/Strip to the insulated pipe using 16 gauge, minimum, stainless steel tie wire. Center the FS-195+ Wrap/Strip in the CS-195+ Composite Sheet so that approximately 7/8 in. (22,2 extends beyond the CS-195+ mm) of FS-195+ Wrap/Strip Composite Sheet surface.
  4. Cut the CS-195+ Composite Sheet to closely follow the contours of the FS-195+ Wrap/Strip around the insulated pipe. Do not allow an annular space greater than in. (6,35 mm) to remain between the CS-195+ Composite Sheet and the FS-195+ Wrap/Strip.
  5. Install the CS-195+ Composite Sheet with the foil side facing into the penetration opening. Apply a in. (6,35 mm) minimum bead of CP 25 WB+ Caulk or Moldable Putty+ around the perimeter of the opening on the concrete before installing the CS-195+ Composite Sheet. To allow for fastening, there must be a 2 in. (50,8 mm) minimum overlap of the CS-195+ Composite Sheet onto the concrete on all sides of the opening.
  6. For seaming details when the CS-195+ Composite Sheet must be cut or joined together, use 3M print #5300-REF1.
  7. Use a in. (6,35 mm) minimum diameter bead of CP 25 WB+ Caulk or Moldable Putty+ to seal the interfaces between the CS-195+ Composite Sheet and the FS-195+ Wrap/Strip, and the FS-195+ Wrap/Strip and the pipe insulation.
  8. Use masonry anchors with washers to secure the CS-195+ Composite Sheet to the substrate. The fasteners are spaced at a maximum of 6 in. (152,4 mm) O.C.

Maintenance
3M Fire Barrier CS-195+ Composite Sheet remains stable for an indefinite period of time. CS-195+ Composite Sheet should be stored in the original shipping container until used. The materials are non-impaired by freezing or storage at temperatures up to 187°F (86°C).
