 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. So simple to install. Very high quality.

    Posted by Philip R. on 18th Jan 2018

    Simple to install, and helps tremendously. Shipping was really fast and packaged perfectly.


  2. Great pipe insulation

    Posted by GM on 17th Jan 2018

    Bought this product because it's made by Owns Corning and was not disappointed. Easy to use and looks nice.


  3. High Quality and Low Price

    Posted by Bill R. on 12th Jan 2018

    First, a quick comparison to the big box stores.
    The big box stores only have 1/2" thick insulation, limited sizes, and the adhesive on the jacketing is weak. I've had to use additional tape to keep the insulation sealed.
    Buyinsulationproducts.com has multiple thicknesses (I purchased 1"), any size you need, and a double sided adhesive on the jacketing. And, buyinsulationproducts.com was still cheaper than the big box stores! I got twice the insulation thickness at a lower price!

    Delivery was fast and it included extra tape for each of the butt joints!

    My heating bills have decreased, all of the radiators are now getting hot, and the house is more comfortable.

    *Bill, I am glad to hear that you are saving money on your heating bills and that you are happy with our pipe insulation quality! ~BIP


  4. Pipe cover

    Posted by Unknown on 11th Jan 2018

    The product worked well. I would recommend it.


  5. Quality & price spot on!

    Posted by Chris on 9th Jan 2018

    MUCH better quality and half the price of the big box shops! Shipped both times right after my order and I had it in 2 days! If I have any other insulation needs I will be a returning customer. Someone removed all my asbestos insulation I had in my basement and I was throwing money away heating my basement. Now that its all insulated what a difference! My radiators are actually HOT! Thank you

    *Chris, we are glad that your radiators are working properly again with the help of some insulation ~ BIP


  6. Great Product

    Posted by Joe on 2nd Jan 2018

    Used this to insulate my steam pipes in the basement. High quality, easy to install, and a great insulator. Highly recommend.


  7. Great Quality and Price

    Posted by Albert D. on 21st Dec 2017

    The product was very easy to install and does a great job of insulating the exposed steam pipes in our basement.
    The prices were about 30% less then anywhere else we could find including Home Depot and Lowes.
    We could also get various sizes to fit different pipes. In the other stores you were limited to about 2 or 3 sizes.
    Our home was built in 1900 and the sizes vary when it comes to a boiler and their pipes.
    I will be purchasing again to complete the job.
    I will definitely refer all to this site.

    *Albert, thank you for the great review and we look forward to your future purchases ~ BIP


  8. 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 with pricing. ~ BIP


  9. Easy install

    Posted by Unknown on 1st Dec 2017

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


  10. 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
