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.

    Perfect for my old steam pipes

    Posted by Eric B. on 23rd Dec 2021

    Removed the old asbestos insulation years ago and finally got around to putting on new insulation. This was high quality stuff, easy to install, with plenty of tape to seal the joints. Very happy customer.

    Pipe insulation for a forced hot water pipe in a garage. Very easy to install and delivered in mint condition with the right measurements. Diameter sizing can be slightly larger than specified on a few of them, but great quality overall.

    Delivery

    Posted by Al on 3rd Dec 2021

    I ordered 200.00+ in pipe insulation, received a delivery date of 12-1 no show, then 12-2, no show, then 12-3 yep no show. The tracking on buy insulation keeps showing out for delivery as does the FedEx link they have, but when I checked with FedEx directly they say they havent received it and they have no date when it will arrive. So my conclusion is that Buy Insulation has been flat out lying to me. If they dont contact me and tell me the truth I will be canceling my order.

    *Al, our online tracking links pull information from the FedEx site. Unfortunately delivery times are out of our hands however I have emailed you about the information we received from FedEx on this delivery. ~ BIP

    Split-sleeve fiberglass pipe insulation

    Posted by DAVID W. on 1st Dec 2021

    I used several length of this insulation over 6 inch diameter heating/cooling ducts on the ceiling of an un-insulated tuck-under garage. I covered them with a PVC wrap and used 90 degree and 45 degree PVC covers for the bends in the system. I used PVC tape to secure the joints. This has greatly reduced the heat loss from the ducts. This has made the rooms served by the ducts much more comfortable. The installation looks quite neat and should stay clean. The insulation is designed for 6 inch inside diameter (schedule 40) steel pipe so the I.D. of the insulation is about 6.6 inches. This leaves about a 0.3 inch gap around the 6 inch O.D. duct tubing. This was not a serious problem.
