ThermalSafe® Fire Resistant Panel

Metl-Span’s ThermalSafe® mineral wool panel is the latest development in fire resistant wall construction technology.

ThermalSafe® combines advanced design with Metl-Span’s sophisticated manufacturing expertise to create a composite panel with a core made from non-combustible structural mineral wool boards to maximize compressive strength.  This fire rated panel has superior structural characteristics and span capability.  Metl-Span has created this mineral wool panel to achieve a one-, two- or three-hour fire resistance rating under the most demanding conditions.  In addition to its fire resistance characteristics, the panel provides good thermal performance and protection from the elements.  The unique LockGuard® interlocking side joint further enhances the fire resistant performance of the panel with its tongue and groove engagement of the mineral wool core.

ThermalSafe Related Projects:

  • The Ark at JFK Airport: The Ark at JFK also utilizes nearly 6,000 square feet of Metl-Span’s 7-inch ThermalSafe insulated metal wall panels, featuring a non-combustible mineral wool core. The panels achieve a three-hour fire resistance rating, helping the design team meet today’s stringent fire codes and bring the 60-year-old cargo facility into the 21st century.
  • Fallsview Indoor Waterpark: The waterpark facilities, situated atop the parking structure, called for local code requirements of a two-hour rating on the firebreak panels installed on the ceilings of the four parking levels. Therefore ThermalSafe panels were installed.
