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 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 pipe insulation and place the opening over the pipe. The fiberglass pipe 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.

Have an exposed drain pipe on my rv. This insulation with heat tape will be a perfect fit for winter, Slipped over the pipe easily and sealed nicely with the added tack strip. Plan to leave on permanently. Affordable,high quality,American made, perfect.
As advertised, works great for the steam lines in our brewery.
Wow!! Ordered on a Thursday morning and delivered next day. Couldn't wait to get started as the basement was a hot box after an asbestos removal. Completed everything - till I ran out of materials. (forgot to measure a section of pipe) Wrapping the elbows and tees was the hardest part. Best to use the tacks and tape for that. Should definitely use a miter box and serrated knife to get straight cuts for the insulation. Now the heat is in the living area rather then the basement. Very pleased with the results.
A decent quality product at a good price. Does what it is designed to do.
Headline says it all.
The fiberglass piping insulation I purchased arrived quickly and in good order. Very pleased with the quality of the product and the price (40% less than Home Depot) compared to the box store version.
Purchased these for home steam pipe insulation, and both times the orders were delivered within two days. This is far higher-quality insulation than anything you can find in big-box stores, at a very reasonable price, even taking shipping costs into consideration.
The jacket is surprisingly durable and the adhesive very easy to work with-- and the inclusion of cut-to-length and easy-to-separate strips of sealing tape are convenient. Would highly recommend the PVC covers for elbows, unions, etc. and picking up additional tape-- and some cutting tools, if you don't have them already, as making clean cuts isn't trivial with a standard short-blade utility knife (aforementioned jacket durability plus thickness of insulation/circular profile).
*Wenshu, thank you for the great product review! ~ BIP
We bought a ton (like four boxes) of pipe insulation after asbestos abatement to insulate our heating pipes in then basement. The insulation was easy to put on and cut to meet our winding system of pipes. When I contacted customer service (despite not being able to return (shipping back was more expensive than the product)) they offered excellent advice on using the mistakenly ordered pipe insulation (which was my fault entirely). Very pleased with the order - it arrived the next day and we’re probably putting in one more order to finish up all of the insulation.
*Maggie, thank you for the great review on our pipe insulation and our website! ~BIP
Wish the salesperson whom I spoke with briefly would have told me to order one size smaller than the diameter of my pipe so that the insulation would have fit more snugly.
*Robert, I am sorry to hear that the pipe insulation was not the correct size. Our customer service reps try their best to guide customers to the correct sizing based on the measurements and info provided. ~BIP
