Kingdder Pipe Insulation Foam Tube 6 Pcs Self Adhesive Insulation Wrap for Copper Pipe Pre Slit Clamp Highly Insulated Foam for Outdoor Winter Irrigation, Sprinkler(1.3 Ft x 0.6 Inch)

Great quality and easy to use.

I've got a tankless water heater on the side of my house and once a year or so we get temps cold enough to freeze the intake/output pipes from the unit. The original insulation that the installer put on had degraded over time and it was freezing up more regularly. I finally broke down and got some heated wire to keep the pipes from freezing and needed to insulate over the top of the pipe and wire.I got the 1" set and was happy to find 3 or 4 feet of sealing tape included in the packaging (I had ordered a roll of tape separately). I assume that this was to securely seal the insulation bits end-to-end. I was also very happy to find how strong the outer silver layer was and how well all of the adhesive bits adhered. There was a lot of overlap, so several inches of extra silver material wrapped around the black foam insulation. I was able to wrap the pipes under my water heater, modifying the foam to fit around all of the valves, wire heating wrap, fittings, etc. It all came out very nicely and I'm very happy w/ the product.

Update: After getting through a couple of layers of wrapping plastic I discovered that this does have the self-adhesive foil wrap. It stops short at both ends and will certainly need foil tape for jointing. In fact I plan to fully wrap in foil tape (spiralled around) after installation for longer life.

we ordered this for our exterior driveway spigot pipes and they are exposed to cold weather etc and these work great. The foil also makes them very visible.

The foam was very pliable and thick, which is good for lines not so straight. The radiate covering was long enough to completely wrap the product on the line, and very good adhesion. It would be nice to get these in longer lengths, but they join together very nice.

Easy

I wrapped outside pipes.Easy to apply to pipes..Adhesion is great...

Much better solution for my rooftop a/c condenser line than what I picked up at the depot - I'm hoping the silver liner tape will make the foam last longer - the installer had used a foam wrap held with tie lines, and in 5 years it was gone in many places. It had no protection against the sun, same thing with the foam at the store - the 6-foot tube was also not long enough, so having the extra bit allowed me to complete the installation without having to buy a whole another foam tube at the store.Having it in sections also made installation much easier, and it comes with the tape to secure the sections together. Unexpected! I had gone up there with silver foil duct tape, but the included tape has some cloth-type material, the same as the tubes. An excellent solution that was installed in minutes!EDIT - have to modify review to add the sticky tape they provide does not stay on - I wrapped the whole thing in foil duct tape and called it a day --
