 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).

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. Amazing product

    Posted by Diana on 3rd Oct 2018

    This fiberglass insulation was so easy to use and install. The self taping feature is amazing. I used a bread knife to cut it when needed. It just couldn't have been easier.

  5. Easy and neat!

    Posted by Todd M. on 7th Aug 2018

    The pipe insulation is easy to cut and install and is finished off nicely with the PVC covers. I'll be measuring the rest of my basement pipe for another order.


  6. Great product, great price, less shipping and handling then others I researched

    Posted by Christopher L. on 6th Aug 2018

    Great product, great price, less shipping and handling then others I researched. Easy to install, convenient PVC fittings for non hassle tees and 9o’s. I have ordered twice And will be doing so again.


  7. Easy to install

    Posted by Unknown on 14th Jun 2018

    This pipe insulation is easy to install and easy to cut out for hard to manage tight spaces and pipe hangers.


  8. Excellent Insulation at a great price!

    Posted by Justin S. on 2nd Jun 2018

    This winter during a very long cold snap in Minnesota I realized my hot water baseboard heat was not keeping up, even though it ran all day. I measured the heat at my first radiator and realized I was losing over 30 degrees in the 15 feet from my boiler to the radiator, which seemed like a ton. After searching around for good insulation and only finding cheap foam insulation I found Buyinsulationproducts.com and ordered some 1" fiberglass insulation. I covered the pipe from my boiler to the radiator and as much other pipe I could get to from the exposed ceiling in my basement and the change was dramatic. Now I lose less than 10 degrees, probably less than 5, really and my house is noticeably warmer and my boiler does not have to work as hard. Very happy to be able to find this in so many thickness options. So much better than foam insulation and pretty easy to install.


  9. Excellent pipe insulation and quality manufacturing

    Posted by Victor P. on 28th May 2018

    Product is easy to work with and the finished outcome looks like Bob Dylan did the job... Will be using it in my next project.


  10. 1" Thick Fiberglass Insulation and Fittings

    Posted by Alfred R. on 8th May 2018

    I have a hot water heating system on the shoreline in Southeastern Connecticut. The wind howls off the water in the winter and the insulation on my 1" copper insures that no heat is lost in my basement which is 80 feet long. Insulating my heating system is the better part of all the money spent on it, the best investment I or anyone else can make for fuel savings in the long run.
    This company sells a good product that is easy to install. Shipping is a bit pricey but that is to be expected with the length of the product.
    Highly recommend purchase from this company.
