Armacell now offers AP Armaflex® pipe insulation for large pipe applications. The new sizes answer the demand for larger tubes, eliminating the need to piece sheet or roll material around large 8- and 10-inch piping. The closed cell structure means that it won’t wick moisture and needs no additional water vapor retarder. The flexible, but durable, fiber-free foam resists punctures and won’t crack or flake over time. When installed and maintained properly, AP Armaflex insulation should last the life of the system. The new sizes include: 8- and 10-inch ID x 1-inch wall; 8- and 10-inch ID x 1.5-inch wall; and 8- and 10-inch ID x 2-inch wall.
