 Product Description

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 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 the pipe insulation we ship is the new Owens Corning ASJ Max 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 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).

SSLII Double Adhesive Closure System: Owens Corning fiberglass pipe insulation comes with the advanced SSLII Closure System which utilizes two strips of adhesive rather than the standard SSL closure system which is has only one strip.  The SSLII system ensures a tight and secure closure of the ASJ Max jacket and prevents any unexpected opening of the jacket after install.

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.

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.

  1. Very easy to use and high quality

    Posted by Alex T. on 17th Mar 2019

    Fits all three pipe sizes I used snuggly. The split design with sealing tape made installation very easy and professional looking. Insulation is a tight design so if you need to cut lengths it is easy and does not compress or come apart.


  2. Great Insulation for Steam Radiator Pipes

    Posted by Roger in Brooklyn on 12th Mar 2019

    I just purchased an old brownstone with a steam radiator system. The furnace tech advised me to insulate the main radiator pipes in the cellar. After looking at inferior options, I found this tubular fiberglass insulation at buyinsulationproductstore.com. It was easy to calculate the insulation size I needed for my 2" cast iron pipes. The product arrived quickly and was easy to install. I ordered additional tape, but probably only need the tape that came with the 13 rolls I ordered. Now, I just need to install insulated elbows and tee's which I just ordered. I recommend this product highly.


  3. Pipe Insulation Fast & Easy

    Posted by Joe S. on 12th Mar 2019

    I had old asbestos insulation removed from my steam pipes. Chose to use 1-inch thick fiberglass. The jackets provided by BIP made the job go very quickly and easily. They also provided tape segments for the joints. The fiberglass was well made, easily cut or hollowed out to fit around pipe connections. They have several videos on line that show the proper way to install the jackets, angles and elbows also the sizing charts took out the guess work. Reasonably priced compared to the national retail stores and showed up at my door within 3 days of placing the order. Definitely would recommend to anyone needing to insulate pipes. Would recommend picking up an extra roll of tape.


  4. Well made product that will save us lots of money

    Posted by Rudy R. on 11th Mar 2019

    I purchased this pipe insulation for the long runs in my basement from the boiler to our radiators. First, each piece was very easy to install, Just pull up the tape, spread it open, wrap it around the pipe and seal the tape. Second, they look great. By the way, I used an old bread knife to cut pieces to length as needed.

    I was especially appreciative of pieces of tape that came with to seal up the seams between pieces. Made it look like one continuous piece of insulation. Looks very professional.

    Finally, and most important, the insulation works great. I used a temperature sensor to compare pipe I did not insulate with the pipe I did. The naked pipe was 135 to 145 degrees. The insulation was 75-80 degrees. That is an amazing improvement and I expect a nice cost saving.

    Thanks to BuyInsulationProducts.com for the great solution and service.

    *Rudy, thank you for the great review and enjoy those lower utility bills! ~ BIP


  5. Owens Corning fiber glass insulation.

    Posted by David B. on 4th Mar 2019

    Great company that sells insulating products.
    Accurate web site that has charts for you to decide. Tutorials are great. The products that I purchased were excellent. They were shipped promptly and was everything I expected.
    I will absolutely purchase from this company again.


  6. easy install good results

    Posted by George R. on 28th Feb 2019

    Great product, the double sided joint tape makes for a much improved install over my local supplier.


  7. Great quality

    Posted by John K. on 21st Feb 2019

    Don't bother with the "Home Depot Cheapo" junk if you want it to stay on. Plus, how can you beat next day delivery?


  8. Easy to install, great looking, too.

    Posted by Chris E. on 18th Feb 2019

    I purchased these pipe insulators to insulate pipes inside apartments. The old steam pipes were uncovered, unsightly and unsafe to touch when hot. These insulators have made a big visual difference, and help the upstairs tenants with their heating bill, too.

    So easy to cut and fit. I've added them to the basement pipes as well. It makes me feel good to be saving a few BTUs for my tenants who struggle with their winter heating bills.


  9. Excellent quality product

    Posted by Charles S. on 13th Feb 2019

    Product is of high quality. Easy to install. Works as advertised.
    No issues.


  10. Easy to use, fits well.

    Posted by Alex T. on 12th Feb 2019

    Pipe insulation fit all 3 sizes I purchased well. No trouble with the sealing tape, and the strips to seal the joints were a nice touch.
