Industrial Insulation Types

There are several factors to consider when specifying insulation for industrial applications. Two primary considerations are choosing the right product for your needs and determining the proper insulation thickness for optimal product performance and efficiency.

Pipe insulation products

Fiberglass Pipe Insulation

Fiberglass pipe insulation is a molded, heavy density, one piece insulation made from inorganic glass fibers and is typically produced in 3 foot lengths—with or without a jacket (though custom lengths may be available from manufacturers). It is used on piping systems in power, process, and industrial applications and in commercial and institutional buildings. Most fiberglass pipe insulations can be used on systems from 0° to 1000°F. Manufacturers’ specification sheets should be consulted to determine the exact temperature range for specific products.

Fiberglass Board and Blanket Insulations

Fiberglass insulation boards and blankets are thermal and acoustical insulation products made from inorganic glass fibers and available plain or with an FSK or ASJ jacketing. Boards and blankets may be used for piping, as well as heating and air-conditioning ducts, power and process equipment, boiler and stack installations, wall and roof panel systems, tanks, valves, etc. They come in a number of densities, thicknesses, and lengths and can be used on systems operating from 0° to 1000°F.

Rock Wool Pipe Insulations

Rock wool (or mineral wool) pipe insulations are precision cut pipe coverings composed of high density mineral wool. This type of insulation can be used in a wide variety of applications for hot and cold piping ranging from 120°F to 1200°F. This product is frequently used in high temperature industrial processes, like power plants, power stations, petrochemical complexes, for steam and process pipe work, and for hot/cold water systems. It is produced in two half cylinders and can be supplied either plain or with one of a variety of facings, depending on the application.

Rock Wool Blanket Insulations

Rock wool (or mineral wool) blanket insulations are flexible blankets that are easily wrapped around pipes, tanks and vessels up to 1200°F. Typical applications include cylindrical high temperature duct systems, large piping, groups of parallel pipes, breechings, and flanged fittings. The product is generally furnished with a facing or jacket and comes in various lengths and thicknesses.
