Palusol is a unique material that is used as a "final stand" for protecting your firearms and other belongings from fire. When a safe becomes engulfed in a house fire the heat causes the Palusol to expand, sealing the safe around the perimeter of the door. This keeps the interior cooler overall and prevents flames from entering the safe through the edges of the door. With the safe sealed, the fireproof materials used in the walls is more effective at protecting your belongings inside. Found on Browning fire safes only.
