3M™ Fire Barrier Composite Sheet CS-195+
ผลิตภัณฑ์ป้องกันไฟลาม
- Four-component intumescent system is ideal for firestopping larger penetrations such as cable trays and conduit
- Forms effective intermittent fire-break within horizontal and vertical cable tray runs
- Hard char material tightly seals penetrations against flame spread, smoke and toxic gases
- Easy to install: cut, form and install using common trade tools for nearly any size
- Thermally conductive: allows unwanted heat build-up to escape, helping reduce derating issues
- Re-enterable for new or retrofit installations
- Firestop tested for up to 4 hours in accordance with ASTM E 814 (UL 1479)
Features
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 28-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.
- 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.
- Easy to install using common trade tools.
- 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.
- 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.
