One Hour Fire Rated Modular Wall Systems

ASTM Certified 1 Hour Fire Rated

Panel Built has installed numerous One Hour systems throughout the country. Both military and commercial customers come to Panel Built for their laboratory tested ASTM certified One Hour Fire Resistant panel system. This specially designed sandwich panel is composed of 5/8” Fire-Shield gypsum board with a mineral wool insulated core and held in place with 26 gauge galvanized steel studs. 20 gauge steel channel is used to secure the wall panels.

Tested by a certified independent laboratory, Panel Built’s One Hour panel has “successfully met the conditions of acceptance as outlined in ASTM Method E119-00a Fire Tests of Building Construction and Materials for a fire endurance rating of 60 minutes.”

For instances where One Hour Fire Rated is not required, but Class A does not suffice, Panel Built has developed a "hybrid" panel. For more information, please contact your Panel Built representative.
