Flex Seal is a quick, cost-effective way to prevent spores and other contaminants from entering affected spaces.

Zeppelin Guys introduces the AIRWALL Flex Seal, an impermeable barrier for sealing wall cavities when a flood cut has been performed. Flex Seal is a quick, cost-effective way to prevent unwanted spores and other contaminants from entering the affected space during a flood cut. The current method requires the use of plastic and tape, as well as other construction materials, such as insulation; a room with 24 bays could take up to 5 minutes per bay, while Flex Seal requires roughly 5 seconds.

Flex Seal can be used in 2- by 4-foot and 2- by 6-foot walls with wood or metal studs. It also works in the common 16-inch on center and the less common 24-inch on center used in some regions of the U.S. It’s composed of flame-retardant material on the front and back that’s white to match the color of the drywall, while clear PVC material on both ends keeps “paw prints” to a minimum. A soft, poly-fill middle layer ensures the tightest seal in the wall cavity, and a structural internal spring provides both the shape and the tension needed to hold Flex Seal in place so professionals can work.
