Armacell now offers flexible AP Armaflex pipe insulation in up to 10-inch inside-diameter tubes for large pipe applications. Mechanical insulation contractors will save time with easier-to-install tubes that curve naturally to fit snugly over large pipes and glue together faster than flat insulation. Added savings will come from reducing the scrap material that comes from cutting sheets down to size for large pipes. The insulation’s closed-cell structure will not wick moisture and needs no additional water-vapor retarder. The 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 mechanical system.
