 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: 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. Great product and great fit

    Posted by Unknown on 21st Sep 2017

    Simply a great product and company


  2. 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

    Posted by Mike on 22nd Apr 2017

    I found the spilt insulation was not hard to install. Cutting with a knife was easy and seal was a snap with the self sealing pull off..

  9. Thanks...

    Posted by Tim H. on 10th Feb 2017

    I just wanted to drop you a quick note and say thanks for helping me make my home steam pipe insulation project worry free. Your web site makes pipe sizing and quantity ordering simple and accurate. Even small suggestions like recommending buying an extra roll of tape for the seams was right on the money. Your quick delivery was much appreciated as well. I'm not one to normally send a letter of appreciation, but as far as I'm concerned your company is top notch and my project came out great because of it.


  10. Works really well

    Posted by Joe on 2nd Feb 2017

    Sturdy, good adhesive, easy to install. Amazingly fast shipping.

    I really recommend the instructional videos on this site too - they're really helpful, well produced, and clear.
