Fiberglass Pipe Insulation
Brand : Owens Corning / Johns Manville
- Unit Of Measure:
- Per 3ft Section
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 pipe insulation comes with a butt-strip tape (matching the white ASJ jacketing) that is used to connect two sections of pipe insulation 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 pipe covering, simply open the hinged part of the commercial pipe insulation and place the opening over the pipe. The fiberglass piping insulation 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.

Easy to install and working great
I bought this pipe insulation for the steam pipes in my basement. The product was easy to install and seals well around the pipes.
Good product ,it just comes in small lengths and can one purchase one at a time. That is very inconvenient .SMH
*Jay, I have reached out via email to understand further what the issue is so we can improve the buying experience. ~BIP
Great stuff. Easy to cut and install.
Product quality and customer service excellent in every way.
This is so much better than the stuff available in home centers. I paid less for the 1 inch thick product than they charge for the 1/2 inch pipe insulation at The HD and it is a much higher quality product. This also comes with pieces of tape to seal the sections together.
These are high quality insulation and you can tell right away. Dont hesistate just buy these, you wont regret it. Better than what you will find at Home Depot and at a better price.
Quality product - much better than 1/2 inch big box stores and less expensive as well.
Website is super-helpful--very happy to have the how-to-install video. Quick shipping of an accurate order. Customer service was helpful in advising on correct sizing. Insulation itself is as expected and pretty easy to install. Problem: Each roll shows a manufacturing date, and some were much older than others (i.e., years old--so why still in the inventory?). And so, the adhesive flap on newer rolls was in much better shape than older ones--not all of the older rolls adhesive peeled or worked as it should, and required application of additional sealing tape to shore up damaged or failed flap adhesives. Older rolls should still insulate properly, but were more difficult to work with/install.
This product is high quality and works perfectly I bought it to reduce heater pipes in my NYC apartment. Customer service are very attentive.
Good quality, good price.
