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):

Installation Instructions:

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.

BUY INSULATION PRODUCTS.COM ONLY SELLS AMERICAN MADE FIBERGLASS PIPE INSULATION PRODUCTS.  DEPENDING ON SHIP TO LOCATION AND/OR PIPE SIZE WE MAY SHIP OWENS CORNING ASJ MAX OR JOHNS MANVILLE MICRO-LOC HP / HP ULTRA INSULATION. PLEASE CONTACT US WITH ANY QUESTIONS.

TIP: We highly recommend ordering a roll of ASJ Max Tape with your order of Fiberglass Pipe Insulation to ensure you have enough tape to completely seal your piping system.  Every cut made between fittings (tees / 90s etc) will result in the need for more tape. ASJ Max Tape also comes in 25'er Short Rolls for smaller projects.

    pipe insulation

    Posted by John on 18th Mar 2020

    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

    It’s just too easy!

    Posted by Desiree D. on 27th Jan 2020

    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.

    Great insulation, but wear protection

    Posted by Eric B. on 20th Jan 2020

    Quality pipe insulation (much better than HD), arrived very quickly and installed easily. As someone else mentioned, having extra ASJ Max tape on hand speeds the install. The measurement help online was great when you've got a lot of varying sizes of old steam pipe. But I should have been more careful with the loose fiberglass fibers. Steam was on, so I was working in a T-shirt and got fibers "everywhere." Definitely my fault, but don't let it happen to you!

    Great Quality & Great Price !!

    Posted by Gene D. on 4th Jan 2020

    Initially bought an inferior product at a higher price from HD. After a bit of research online I found this website & decided to give it a shot.
    VERY pleased to find that I received a MUCH BETTER product for a lower price AND UNBELIEVABLY FAST SHIPPING.
    Also - The instructional videos were MUCH MORE informative than ANYTHING that those BIG BOX stores can offer.
    I RARELY make recommendations but in this case I have already told 2 people about the website !!

    THANK YOU !!

    *Gene, thank you for the great review, we really appreciate the compliments and the referrals! ~BIP

    Great Product - Not so great chart

    Posted by Andy from New Hampshire on 10th Dec 2019

    I purchased the 1" thick pipe insulation for my residential steam system. Anecdotally speaking... my basement is now less warm, my living spaces are slightly warmer, and my boiler is firing less to keep the temperature the same. Goals accomplished.

    Tips for any other clueless homeowners, such as myself.:
    -The self-adhesive strip really needs be rubbed on to get it to stay adhered.
    -Try to keep the outer jacket of the insulation dust free (difficult in my crawlspace) as it will help with the self-adhesive strip.
    -You will use more ASJ Max tape than you expect!
    -Use sharp/new razor knives to cut it. Cuts easy!

    It's a great product, and easy to work with, but rated 4 out of 5 because I found the sizing chart confusing. It's difficult to access some of my pipes so I used calipers to measure the OD. Some of my pipes were different sizes from what was listed in the chart so I had to "guess" as to what to order. Lucky for me only 10 pieces were unusable so I ordered a second batch a size up/down from my original order.

    When in doubt... call 888-367-8931
