Questions & Answers

What is the diameter of the hole in this insulation?

Are you basing the description of the pipe, as in the ID is 1 1/4" while the OD is 1 1/2"?
Asked by: glenn32
The product description indicates this is for 1 1/4 inch copper pipe. I installed it on 1 1/4 inch copper supply/return lines for in-floor, radiant heat. The insulation fits loosely on the pipe (thus providing an air gap to help with insulating the lines.

Rated 2 out of 5 by from Bad tape It's insulation, right. What can be bad about insulation. As other reviewers have said, the tape on this product doesn't work. Day after installation, it will open up. Don't buy t

Rated 1 out of 5 by from Garbage After getting rid of the all the asbestos insulation headed to HD for some replacement - just about fell over at the price, but had to get it. Then after spending a day in the basement installing them I was VERY DISAPPOINTED to come downstairs the very next morning to see all the adhesive failing and the foil literally falling off the pipes..... pure garbage, but i am stuck with them as they are paid for and installed. Now I have to find a way to get some type of high temp white paper tape to hold them together...... avoid at all costs

Rated 5 out of 5 by from gets the job done. fits perfectly around 3 Inch pipes and stops the sweating of pipes. should use gloves and long sleeves cause insulation is very itchy when it comes in contact with skin.

Rated 3 out of 5 by from Does the Job Read the other 'poor' reviews before purchasing and have to agree with most of what was reported. Product DOES go on easily and once you develop a technique for getting the self-adhesive seal to work the job goes more quickly ...BUT the adhesive is poor and will come apart so take the advice of another reviewer and use 'cable ties' or good duct tape at the ends of each unit. I used duct tape to join the units together and this eliminated the 'paper separation' issue. I used this product on in-floor, radiant heat copper supply lines so I do not get temps above 115 degrees. ...and did NOT have any problem with the insulation coming apart due to high temperatures. I DID like that the fiberglass was easy to trim/fit around pipe joints and between pipe hangers. I did like that the insulation opened for easy installation (take care not to spread it too wide as this may cause the insulation to come apart and may cause it to separate from the paper sheathing. I installed 70 feet and YES, I thought it was quite expensive ...more than it's counterparts on the shelf. But I did NOT want foam insulation and opted for the fiberglass. I tried the 'wrap-type' first. It was inexpensive but it DID NOT WORK well. Took it back and got the product being reviewed. Expensive, yes. But it is doing the job and over the long run it will pay for itself by reducing heat loss from the boiler supply line. DO WEAR gloves as the fiberglass will get on your hands/wrists with the typical results of handling fiberglass. Since I was installing this above my head I also wore a hat/glasses and face mask.

Rated 3 out of 5 by from so-so product The product is easy to install and cut, but a few problems: - the adhesive fails at high temps. if using to insulate steam pipes, use cable ties - some of the fiberglass tubes come out of the paper wrapping fairly easily. handle with care - why is this product so expensive? wish it was a little cheaper.

Rated 5 out of 5 by from fiberglass pipe insulation Wear googles and long sleeves to prevent getting fiberglass in you eyes and on your skin. Respirator mask is a good idea too. Nice to have tape to seal seams. Be sure to order good quality tape to seal ends so fiber is not exposed.
