Metl-Span’s ThermalSafe® mineral wool panel achieves a one-, two- or three-hour fire rating for walls and 1.5 hours for ceilings to help ensure your material, property and people are safeguarded from fire. The insulated metal panel is made with non-combustible structural mineral wool core maximizing compressive strength with an exclusive double-tongue and groove interlocking side joint, LockGuard, further enhancing the fire resistant performance
The ThermalSafe® insulated metal panel meets the required ratings required for today’s buildings through Intertek and UL fire approval, in both US and Canada. This fire rated panel has superior structural characteristics and span capability. In addition, the panel provides good thermal performance and protection from the elements.

“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.”
“IMPs go up a little quicker and there’s a lot less effort and coordination involved. The ease of installation and the effect on our schedule was an important factor.”
