    Alley-K pipe insulation is a preformed fiberglass pipe insulation product composed of high quality glass fibers bonded together with a thermosetting resin. The 36" pipe sections are available with all service jacket (ASJ), which is reinforced with glass fibers and come with a factory-applied, pressure-sensitive self-sealing lap closure system (SSL). 

    Manson Insulation fiberglass pipe insulation is intended as a thermal insulation product for hot and cold service piping. Typical uses include domestic hot and cold water, hot water heating, high temperature, dual temperature, steam, condensate and refrigerated lines. 

    This product uses ECOSE® Technology, a patented, plant-based binder - a smarter alternative to the phenol/formaldehyde (PF) binder traditionally used in fiberglass products. The bio-based binder holds the product together and gives the product its unique appearance. All of Manson's product are formaldehyde-free and made from sustainable resources, such as recycled glass and sand. Manson products are made with a minimum of 50% recycled glass—resulting in recycling of an average of 26 million bottles each month.
