Fiberglass pipe insulation, commercial pipe insulation, copper tubing insulation, Iron pipe insulation.

Knauf 1000 fiberglass pipe insulation is the insulation contractors choice of fiberglass insulation. It is produced in 3' lengths with a factory-applied ASJ jacket that acts as a vapor barrier to prevent condensation. Fiberglass insulation is ideal to retard heat loss or gain for copper tubing insulation, and iron pipe. Knauf insulation is an industry leader in fiberglass insulation products and passes most commercial building fire test requirements (please see below for more details).
Info on Knauf Fiberglass Pipe Insulation
Knauf 1000 Pipe Insulation is a molded, heavy-density, one-piece insulation made from inorganic glass fibers bonded with a thermo-setting resin. It is produced in 3' lengths with a factory-applied jacket. The jacket is a white kraft paper bonded to aluminum foil, and it is reinforced with a fiberglass scrim. The longitudinal lap of the jacket is comes with self-sealing adhesive, and a butt-strip is furnished for each section.
Knauf 1000 Pipe Insulation is used in to retard heat loss in power, process and industrial applications, and in commercial and institutional buildings where maximum fire safety, resistance to physical abuse, and a finished a appearance are desired. Additional weather protection is needed outdoors. Please email us for additional weather protection and jacketing. Insulation inner and outer diameters comply with ASTM C 585.
