Owens Corning ASJ Max FIBERGLAS™ Pipe Insulation

Manufacturer: Owens Corning
Product Description

Owens Corning has revamped the ASJ SSL to ASJ MAX. Now Owens Corning ASJ Max FIBERGLAS™ Pipe Insulation is a durable, cleanable, poly-encapsulated paper jacket that doesn't support mold or mildew growth. The new SSL® Max closure system was designed to work specifically with the jacket to provide a tight, reliable seal that doesn't need glue or staples. It can tolerate intermittent, short-duration precipitation during construction. It has a maximum operating temperature of 1,000? F (with heat-up schedule).

Product is intended for professional installation in commercial and industrial applications only.


Standards, Codes Compliance

Key Features

  • The ASJ Max jacket is tougher than standard ASJ. It has a polymer coating that helps resist water staining and yellowing, and does not support mold or mildew growth, when exposed to intermittent, short-duration precipitation during construction.
  • ASJ Max is designed to have a compatible finished job appearance with standard ASJ.
  • SSL II® Positive Closure System has a new, advanced adhesive that fastens and installs with no need for staples or mastic. Closure system is fast, neat and foolproof, and combines with the butt strips to provide effective long term vapor sealing of the longitudinal and butt joints.
  • Short pieces of insulation can be cut without jacket loss and the section will not come apart in handling. Butt strips come in sealed bags inside the carton so they can stay clean until the moment of use.
  • Fiberglas™ Pipe Insulation’s low thermal conductivity contributes to lower operating costs of heating and cooling equipment.
  • ASJ Max can resist short durations of liquid water exposure that can occur during construction.
  • Our FIBERGLAS™ Pipe Insulation now operates at a maximum temperature of 1,000°F (with heat-up schedule).
  • This product does not contain decaBDE.
  • UL Labeled for flame spread rating of 25 or less and smoke developed rating of 50 and is full building code compliant.

Product Applications

Insulation of hot, cold, concealed and exposed piping operating at temperatures from 0°F (-18°C) to 1,000°F (538°C) (with heat-up schedule) in commercial buildings, industrial facilities, and process or power plants.
