ALLEY-K™ Pipe Insulation
Knauf Insulation Earthwool® 1000˚ Pipe Insulation is a molded, one-piece insulation made from inorganic glass fibers bonded with ECOSE® Technology. It is produced in 3' lengths with or without a factory-applied jacket. ASJ+ is the newest generation all-service jacket composed of aluminum foil, reinforced with a glass scrim bonded to a kraft paper interleaving, with an outer film layer. This jacket leaves no paper exposed, allowing for easier cleaning.
Manson ALLEY-K™ Pipe Insulation is available with or without the standard all service jacket (ASJ).
