Fiberglass Pipe Insulation
Brand : Owens Corning / Johns Manville
- Unit Of Measure:
- Per 3ft Section
- Size is NOT Diameter:
- Refer to Sizing Instructions
Fiberglass Pipe Insulation covering is intended as a thermal insulation for both hot and cold service piping from -20°F to 1000°F. The pipe insulation is molded from heavy density resin bonded glass fibers that come in 3 foot long hinged sections. The fiberglass is wrapped with white All-Service Jacketing with a self-sealing lap (ASJ/SSL) for a quick and secure installation. Each 3 foot section of commercial hot and cold pipe insulation comes with a butt-strip tape (matching the white ASJ jacketing) that is used to connect two sections of fiberglass pipe insulation covering together.
Typical Uses Include:
- Domestic Hot & Cold Water Pipes
- Hot Water Heating Pipes
- High Temperature Pipes
- Dual Temperature Pipes
- Steam Pipes (Low to High Pressure)
- Condensate Lines
- Refrigerated / Chilled Liquid Pipes
Choosing The Correct Size: There are two sizes you need to choose when ordering, the "Pipe Size" and the "Insulation Thickness". The insulation thickness is the wall thickness of the fiberglass which varies from 1/2" up to 3" thick. For help selecting a fiberglass pipe insulation thickness see our Fiberglass Thickness Guide To determine which Pipe Size to order please see the link below (Note: Pipe Size is NOT the same as the pipe diameter):
To install hot and cold pipe covering, simply open the hinged part of the commercial pipe insulation and place the opening over the pipe. The fiberglass piping insulation covering will self-close around the pipe. Once the fiberglass is fitted snug around the pipe, peel the release paper from the self-sealing lap and press the ASJ/SSL jacket closed from the middle towards the edges of the pipe insulation. Make sure to rub the jacket closed to ensure a secure seal. Seal two sections together with a piece of butt strip tape making sure to rub the tape to create a secure seal. Additional ASJ MAX Tape is recommended for large projects and projects that require multiple cuts of the insulation. Use of PVC Fitting Covers for elbows, tees, unions and other pipe fittings should be installed after installing fiberglass pipe insulation.

White ASJ Jacketing: A large majority of common size pipe insulation we ship is the new ASJ Max / HP ULTRA pipe insulation while some larger sizes and (3 x 1/2, 3-1/8 x 1/2, 4 x 1/2, and 4-1/8 x 1/2) will be Johns Manville Micro-Loc HP. The new ASJ Max / HP ULTRA jacketing has a poly top-coat over the ASJ paper which makes it easier to wipe clean and slightly water resistant (cannot be left exposed outdoors).
NOTE: Each unit is 3 linear feet of pipe covering. For example, if you need 9 linear feet, you only need to order 3 units.

My wife and I used the Owens Corning fiberglass pipe insulation in our DIY project to make our residential boiler system more efficient. The product is high quality and application is simple. We particularly appreciate the adhesive system, which works well and promises to be durable over time.
Nice product. Easy to install. Good price. Fast shipping.
Great Product. And service Thank You
Easy to install. Changed my hot NYC apartment into somewhere livable in a few minutes!
Very good quality. Used hundreds of feet of this in various sizes to cover radiator pipes in early 1900 home.
Easy to use and cut to shape. Tape feels very long lasting. Looks fantastic, especially with the PVC fittings.
Excellent quality insulation. Paying for shipping isnt ideal but the quality makes it worthwhile.
Removed the old asbestos insulation years ago and finally got around to putting on new insulation. This was high quality stuff, easy to install, with plenty of tape to seal the joints. Very happy customer.
Pipe insulation for a forced hot water pipe in a garage. Very easy to install and delivered in mint condition with the right measurements. Diameter sizing can be slightly larger than specified on a few of them, but great quality overall.
