ThermalSafe® Fire Resistant Panel

Metl-Span’s ThermalSafe® fire-resistant panels meet the required ratings for ASTM E 119, CAN/ULC 101, and UL 263 through Intertek and UL+ fire approval, in both the U.S. and Canada. ThermalSafe achieves a one-, two-, or three-hour fire rating for walls and 1.5 hours for ceilings, making it the fire-resistant panel of choice. These fire rated metal panel systems maximize fire resistance performance, ensuring properties and people are safeguarded from fire.

ThermalSafe fire rated metal panel systems are made with a non-combustible structural mineral wool core to maximize compressive strength. They also include LockGuard®, an exclusive double tongue-and-groove interlocking side joint, to further enhance the fire-resistant performance.

These UL fire rated panel systems provide efficient thermal performance and protection from elements and are ideal for industrial and high fire risk building applications.

You can choose from a variety of profiles including Santa Fe, Striated, and Ultra-Light Mesa. Contact our representatives today for assistance in choosing the best panel option based on your unique needs.

Design Features and Benefits

  • Resists high temperatures, does not burn or release gases in a fire
  • One-step installation that can easily be disassembled and reinstalled
  • Will not expand as it is dimensionally stable and water repellent 
  • Sound reduction acoustical properties due to mineral wool

Colors

1.  Metallic paint finishes will exhibit color shift, shade variances, striations and longitudinal patterning that are inherent characteristics and are not a product defect or cause for rejection.

2.  All Metl-Span colors are formulated to provide maximum energy-efficiency and solar reflectivity.  All standard available Premium I and Premium II colors have been formulated for maximum solar reflectance.

3.  Prices vary by color, gauge and quantity of metal.  Please contact your Metl-Span representative for complete information.

4.  All colors shown are approximate actual finish colors displayed as accurately as possible.

5. Light Stone – Tuff Cote® does not match the Light Stone – Standard SP color offering.
