 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 (ASJ) which has a self-sealing lap (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 an 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 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 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).

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. Half the price of other stores!

    Posted by Greg J. on 6th Dec 2017

    I looked online and found **** had the 2-1/8 x 1 (they say size 2-5/32") and they were $12 each piece! I kept looking and found it here for more than half the price! The site is also much easier to navigate and had instructional videos, guides, charts, etc. I spoke to a woman on the phone and she was extremely nice and double checked everything with me before I placed my order. They shipped out the very same day and it arrived 2 days later!

    *Greg, Thank you for your great review and we are happy to have saved you money. We had to edit your review to exclude store names. ~ BIP


  2. Easy install

    Posted by Unknown on 1st Dec 2017

    Very easy to install this fiberglass pipe jacket.
    Fits extremely well.


  3. Perfect for the DIY-er

    Posted by Bruce L. on 13th Nov 2017

    Very satisfied with this company and the products I purchased. They arrived the next business day, and I've been happy with the quality.

    I needed to insulate the pipes for a forced steam heating system. The tools and instructional videos on this website made me realize I could do this myself. I recommend getting the pipe caliper to make sure you order the correct size. It was important for me because my basement has both iron and copper heating pipes, and the main system and the branches were different thickness. In addition to providing the fiberglass insulation in the correct sizes, they offer PVC joint covers for 45's, 90's and T's give it a tight and finished look.

    *Bruce, we are glad you decided to take the project on yourself! ~ BIP


  4. Easy to install, excellent product

    Posted by Rudy G. on 13th Nov 2017

    This product exceeded my expectations. I am not a pro and have never done this type of work before but I found it very easy to complete this job. The connecting tape that was included with my order made the job look professional. Even my wife was impressed. Only problem is that it may have added to my to do list since she now knows that I CAN do things.

    *Rudy, I'm glad your project came out better than planned, and we apologize for adding to your chores at home!~ BIP


  5. Excellent product!!

    Posted by Timothy T. on 3rd Nov 2017

    Where do I begin?! This fiberglass pipe insulation is extremely well made. Not only is this cheaper than the stuff available from Home Depot or Lowe’s, but you can immediately tell the quality is far superior. These feel much more sturdy, and the adhesive holds much better than the ones from big box stores. The stuff I purchased from Lowe’s feels cheap and the adhesive came apart on its own in a few days...

    *Tim, its great to hear that you are happy with our products! ~ BIP


  6. Great product and great fit

    Posted by Unknown on 21st Sep 2017

    Simply a great product and company


  7. High quality and easy to install

    Posted by Tom S. on 19th Sep 2017

    The fiberglass pipe insulation is very easy to install and has a good finished look after the joints are covered with the tape that comes with the sections of insulation.
    One tip that I found helpful is to wait until all the sections are in place before removing the paper that covers the final seal along the insulation opening.
    This cannot be done on any pieces that are covered by a fitting ( T or elbow ) but all other sections can have the final seal applied after everything is in place.

    *Tom, thanks for the tip! ~ BIP
