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 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.

The delivery of my order was in one day unbelievable, fantastic service
Great Product. This insulation was used to insulate, Hydronic Copper pipes. The best product I have found so far. Thank You
Great product and arrived on time
Cheaper, easier install & better R value.
I purchased this to wrap my 4” dryer vent. Excellent product. Worked perfectly. Highly recommend.
Excellent quality. Reasonable price. Quick shipping
Great product. Easy to install
Almost half the price of the big hardware stores.
High quality brand name insulation was delivered quickly.
The price was much lower than any other suppliers.
good product but the adhesive strip and tape does not hold up
*John, Please keep in mind that the lap tape is a PSA (pressure-sensitive acrylic) which needs to be rubbed in to break the adhesive crystals which creates a permanent bond. ~ BIP
Why didn’t I buy this years ago. Installed 84’ of 1” steam pipe insulation and can not wait to see how much we will save in heating cost. Great quality, perfect thickness and comes with extra tape! I did purchase an additional 150’ of tape and it does come in handy
This insulation was easy to cut to fit and is a great improvement over what was on our backflow valve. Very pleased.
I have an older home and this kind of product readily available at the usual big box stores and local distributors . I found the products on this site to fit every need. Great prices professional staff prompt shipping
