Answer: 
Aluminum HVAC tape. HD has quite the selection. Thinner stuff works better for this fragile/soft pipe wrap.

Answer: 
Hey Rich,
The foil side goes outside, so the insulation can more effectively insulate the pipe.

Hey Rich,
The foil always goes on the outside, so that the insulation effectively wraps around the pipe.

Temp rating/ Use on Boiler pipes?

This question is from 3 in. x 25 ft. Foil Backed Fiberglass Pipe Wrap Insulation
Asked by
Read all my Q&A
October 3, 2016
One Frost King answer indicates that the temperature rating is 165˚. Other answers say that it is OK to use on boiler pipes. My boiler runs around 180-190˚F. So which is correct, is it rated for 165˚ or is it safe for use on boiler pipe? It doesn't seem as though both can be true.

It cannot be used in the first 3 feet of pipe coming out of boiler. After that it is ok.

Rated 4.0 out of 5 by 16 reviewers.
Rated 5.0 out of 5.0 by Just what I needed Running some pipe thru a cement slab, needed to protect it from soil movement. Cheap and good! October 7, 2016
Rated 3.0 out of 5.0 by messy but cheap Wrapped this around 4 inch pvc pipe that carries plastic hot water pipes. it is easy enough and appears to help. Hot water heats up quicker because it is retaning heat many feet away from boiler. However, it is very messy. Expect to be coverved with fiberglass particles especially if your pipe is overhead. Dress appropriately. So over all I'd say it works but not something you want to work with much. July 19, 2016
Rated 5.0 out of 5.0 by Perfect for furnace pipe. It was the right width and length for the furnace pipe. April 12, 2016
Rated 5.0 out of 5.0 by Irrigation System This wrap is the thing to have to wrap around my well water lines so they will not freeze in the winter. Very easy installation and will get around any part of the lines. March 1, 2016
Rated 5.0 out of 5.0 by Very good product! This stuff is si easy to use and handy to keep around! I use it on my faucet stands outside and on my camper pipes and drains, January 12, 2016
Rated 4.0 out of 5.0 by It did the trick............. Working with fiberglass is always tricky. The wrap did the job to keep the pipes warm. That's all that mattered. But be sure you wear goggles and a mask. We were working under the house and had to look up when we wrapped the pipes. Got a lot of fiberglass in places we didn't want it. December 26, 2015
Rated 3.0 out of 5.0 by Functional Product, once placed serves its purpose. When removing from packaging the foil portion immediately wanted to detach from insulation. Fumbling with keeping the foil intact was a minor frustration otherwise easy to apply. January 5, 2016
Rated 3.0 out of 5.0 by Foil Backed Fiberglass Wrap Insulation for Pipes The tape was wrapped in a clear plastic sealant. It was easy to open and unroll. I was able to wrap a pipe with the tape without any help from a pro. January 5, 2016
