 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. The self adhesive for 10 of the 17, 2 inch covers would not seal together..

    Posted by Lou M. on 7th Feb 2019

    The plastic strip which covered the adhesive was stuck to the pipe cover and would not come off. I had to install the cover and go back and tape the covers all separately. The 3/4 and 1 1/4 covers all worked correctly. The shipping cost were very high but, claimed 1 day. They didn't come for 2 days. 2 day shipping should be much cheaper.

    *Lou, I am sorry to hear you were not pleased with our Owens Corning product or our shipping speed. I have passed this info on the malfunction of the SSL-II release tape to Owens Corning. We will reach out to you via email to discuss solutions to your problem. ~ BIP


  2. Excellent insulation

    Posted by Matt Y. on 4th Feb 2019

    I have used various sizes and it works well. The size scale makes ordering easy


  3. Easy effective pipe insulation

    Posted by Tom C. on 30th Jan 2019

    Easy to measure, thanks to your guides, easy to install. Our entire basement looks and feels much better. Thanks so much!

    *Tom, this is great to hear, you are very welcome ~ BIP


  4. Superior quality

    Posted by Paul N. on 10th Jan 2019

    I am not a professional installer but the finished product looks wonderful. My steam boiler had areas of insulation removed leaving bare hot pipes and exposed edges of asbestos. The insulation I bought was easy to cut and altering the thickness of insulation for joints was easy using stock knife. Using z tape and plaster wrap to blend into previous insulation was a little messy but left a nice blended result My furnace room is now s lot cooler and none of the insulation has popped open along seams. Much more professional looking than the wrap that was on there before and it ended my issues with exposed asbestos.


  5. Pellet stove pipe insulation

    Posted by Ralph G. on 5th Jan 2019

    I applied your pipe insulation product to cover a 4 inch metal pipe going up inside masonry chimney for my pellet stove. I chose your product for two reasons. First it will withstand 1000 degrees F, which is much more than needed. Also the outer covering should keep everything in place for long life. I did not require the split as I was lowering the product down the chimney from the top. The included joint strips worked well to join the 3 foot sections (6 total). The final section required shortening to about 14 inches. This was done with a sharp utility knife no sweat. This product is available in a number of diameters. I recommend it.


  6. Superior product-Great service!

    Posted by Alan M. on 3rd Jan 2019

    I recently ordered fiiberglass steam pipe insulation. The product was very easy to install due to the design of its adhesive fastener. In addition, extra tape strips for use in joining each length were included. My basement is now much cooler, which tells me heat is going up into the house, where it belongs. Thanks very much! I will definitely do business with you again.


  7. Highest Quality, REALLY Sticky Tape, Fast Delivery

    Posted by Charlie E. on 1st Jan 2019

    I bought two boxes of 2 different size pipe insulation for boiler pipes in a basement rental. The boxes arrived in 2 days, way faster than I was expecting... or was prepared for! The count of blended sizes was perfect.

    The insulation is better made (higher quality) than can be found in box stores, and the peel-off sticky tape held more firmly than I expected, as well.

    I will buy from BuyInsulationProducts again in a heartbeat. They were recommended by my boiler maintenance guy, the (steam) Boiler Whisperer.

    Thanks! Charlie E.


  8. Quality product

    Posted by Michel N. on 29th Dec 2018

    Excellent quality product, way superior than what can be found in the well known Home Centers.
    Size chart for selection and staff very helpful.


  9. Could not be happier!

    Posted by Timothy S. on 27th Dec 2018

    I could not find what I wanted in the local big box stores (you know who they are). It was such a relief to find this site and be able to order what I needed at a great price and have it delivery quickly trouble free. For now on I will check here for all my insulation needs and save myself wasting time driving around trying to find products the others don't have.
    Thank you, Tim


  10. Were it not for the shipping costs...

    Posted by Humberto R. on 25th Dec 2018

    I'd give them a better rating if I didn't think their shipping costs were excessively high! Just can't figure out why they're so expensive. It's not like the rolls of fiberglass insulation for pipes are heavy (it's foam!) nor long (at 3 feet). The high costs of shipping made me think about the purchase 3 or 4 times and looking through the big box stores to see if I could get the same insulation with their free shipping to store option. I wasn't able to.

    As for the pipe insulation, the winter here has been quite quite mild! So it's hard to say if the insulation has been effective. It was easy to put on aside from crawling around in the crawlspace under the pier & beam house. That's never fun! Product was easy to cut with long kitchen knife. I ended up not using the recommended tape and just tied things up using some velcro since I want to be able to remove the rolls of insulation should the need arise! Used them on 3/4" PEX & C/PVC plumbing. I'd recommend going with the 1/2" pipe insulation despite their chart recommendation of 3/4" as I noticed the 3/4" insulation hole was a little too big for the 3/4" plumbing. The 1/2" pipe insulation fit better, a bit more snug.

    Maybe January will hit us with some freezing temperatures but so far hard to say if they'll work. I think and hope the pipe insulation does work! So I can avoid having to use heating pipe tape and not worry about possible fire hazards!

    Would I buy from them again? Yeah! But only after checking out other options for possible shipping costs relief! Their instructional videos were very nice, just not 25%-of-the-total-price-of-the-purchase-in-shipping-costs-nice.

    *Humberto, unfortunately shipping costs for pipe insulation are expensive compared to the price of the material. The boxes we ship are very large and bulky even though they are light weight they still are expensive to ship. Stores that offer free shipping are building the cost of shipping into the material cost so we recommend comparing total costs for an accurate comparison. Also please note that 3/4" Pex Tubing is the same as copper tube size so 1/2" is the correct size to use from our site (order 1/2 x). We are sorry to hear that you were not 100% happy with our products and service. ~ BIP
