ThermalSafe fire-rated panels

ThermalSafe is Metl-Span's fire-rated insulated panel. It has steel faces bonded to a non-combustible mineral wool core and is rated for one, two, and three hours on walls and three hours on ceilings. These panels go between occupancies, around hazardous processes, along property lines, and in cold storage buildings where code requires a rated separation.

The panels also insulate. Metl-Span lists a 4 inch panel at about R-14.5 and an 8 inch panel at about R-29. They're 42 inches wide and run up to 40 feet long depending on thickness.

Installing to the listed details

A fire rating comes from testing a complete assembly: the panel, joints, fasteners, penetrations, and door frames. If the installed wall doesn't match what was tested, it may not carry the rating on your drawings. We install to the listed details.

ThermalSafe uses a side joint called LockGuard, a double tongue and groove that has to be fully seated. Our work in Dallas included ThermalSafe panels up to 8 inches thick.

Other mineral wool panels

Your architect or the local authority sets the required rating. If your spec calls for a different manufacturer's mineral wool panel, such as Kingspan K-Roc, we follow that manufacturer's listed details.
