There are lots of reason to use fire-rated panels. These panels are special solutions that thermally insulate one area from another & contain a fire to allow the occupants of the facility time to evacuate. DuraWall panels are listed for 1- and 2-hour fire ratings depending on thickness. Feel free to reach out to DuraSystems today to find out more about our DuraWall fire rated panels. for more: https://www.durasystems.com/panels/durawall-fire-rated-panels/
