Armacell AP Armaflex Pipe-Insulation Tubes
AP Armaflex pipe insulation is now available in up to 10-in.-inside-diameter tubes for large-pipe applications. The new sizes eliminate the need to piece sheet or roll material around piping. The tubes curve naturally to fit snugly over pipes and glue together faster than flat insulation. Featuring a closed-cell structure, the insulation neither wicks moisture nor requires additional water-vapor retarder. Meanwhile, the flexible-but-durable fiber-free foam resists punctures and will not crack or flake over time.
