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 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 commercial pipe insulation and place the opening over the pipe. The fiberglass piping 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 common size pipe 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.

    Wonderful customer support and great product

    I searched high and low to get good advice, and a good source, for buying insulation for the hot water pipes in my basement that feed my radiators. The customer service folks at Buy Insulation Products were patient and knowledgeable and helped me pick out exactly the right product, which I could not find elsewhere. The fiberglass pipe insulation I got is super easy to install, reasonably priced, and is completely insulating my pipes.

    Pipe Insulation Price/Availability

    I was surprised when the initial order of pipe insulation was at my door within 2 days. The second order was 10X as much insulation and that arrived within 5 days. Prompt delivery is key to quality service. Thanks

    Super High Quality

    Posted by Marylyn K. on 16th Feb 2021

    We are installing this insulation ourselves on antique heating pipes in our basement. We find it very well made and easy to handle. Since its fiberglass, we are using masks and goggles. We can see it is making an immediate improvement in energy efficiency, even before we finished installing. (We have yet to wrap the elbow joints.) Our heater is not running as frequently or for as long a period, yet the house temperature is the same. The Customer Service folks were friendly and helpful in guiding me to order the right sizes, since our antique pipes are not labeled and our hand measurements didnt always match the sizes on the charts. Wish we had bought this years ago.

    Steam pipe insulation, 1 inch thick

    Posted by Benjamin on 8th Feb 2021

    This is better than the Frost King stuff you buy at Home Depot. You get a choice of R-values (thicknesses). The plasticy cover is better than the paper-feel cover on the Home Depot stuff.
