To further complement the exceptional function and performance of the ThermalSafe^® panel, Metl-Span^® has obtained fire ratings for fire door and window assemblies. These assemblies are tested and certified by UL for 1 hour and 1-1/2 hour fire resistance ratings for use in 1 hour and 2 hour rated walls. These are exclusive assemblies incorporating the ThermalSafe panel and are the only fire door and window assemblies listed by UL for use with mineral wool core wall panels.

Metl-Span’s ThermalSafe fire-resistant insulated panel core is made from non-combustible structural mineral wool boards that are processed in the factory to maximize the core’s compressive strength. This gives the resulting panel its superior structural characteristics and span capability.
