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 commercial hot and cold pipe insulation comes with a butt-strip tape (matching the white ASJ jacketing) that is used to connect two sections of fiberglass pipe insulation covering together.

Fiberglass Pipe Wrap Uses:

  • 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 fiberglass pipe insulation, 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 hot and cold pipe covering, simply open the hinged part of the commercial pipe insulation and place the opening over the pipe. The fiberglass piping insulation covering 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 common size fiberglass pipe wrap insulation we ship is the new ASJ Max / HP ULTRA 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 / HP ULTRA 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.

BUY INSULATION PRODUCTS.COM ONLY SELLS AMERICAN MADE FIBERGLASS PIPE INSULATION PRODUCTS.  DEPENDING ON SHIP TO LOCATION AND/OR PIPE SIZE WE MAY SHIP OWENS CORNING ASJ MAX OR JOHNS MANVILLE MICRO-LOC HP / HP ULTRA INSULATION. PLEASE CONTACT US WITH ANY QUESTIONS.

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.

    Product Helps Immensely

    Posted by Lindsay J. on 2nd Feb 2024

    The fiberglass insulation was super easy to install on the steam pipe in my apartment. I had to cut the insulation in a few places due to the location of the pipe, but it fits great and looks clean.

    The website sizing chart was very helpful when selecting my item. As a DIY project, the pipe insulation was easy to work with. As nice to have, would have been a few premade T and elbow pieces but I Micky moused them with white duct tape from my local DIY Box store.

    Better than anything else Ive found

    Posted by Sam on 25th Jan 2024

    I needed to quickly insulate steam mains in a house we just purchased, and the price and quality here was above and beyond every local store. Fast shipping, easy installation, and the tape holds much better than other insulation I've used in the past.

    Great product

    Posted by Mark D. on 8th Dec 2023

    I was totally satisfied with this product. It was easy to use and put up. I had no problems and was able to fit around other pipe connections with a simple cut with a razor tool. I taped them with duct tape for extra insurance they would stay up, but the sticky tape looks really strong on its own. I would recommend this product.
