Hold on! What size pipes do you have? That insulation you mentioned is for a large pipe such as drain, not typical water line. 2 1/8"? You need insulation diameter just larger than pipe size such as 3/4" for 1/2" line. Maybe a bit larger for space for the heat tape, however, like maybe 1".
Also, the heat tape needs to go on the pipe before the insulation is applied.
You might also consider fiberglass pipe insulation in a roll you wrap around the pipes. Also available on Amazon. That was how I used to wrap pipes before the other kind became popular (the 1960's).
I can't find anything locally short of buying an entire carton - we only need approx 12'. Amazon has this - but I'm not sure if ⅜" thickness is enough. And/or, we had planned to wrap it with the heat tape like the pipes in the barn are, but again — how much is enough - too much? If we have to give $100+ for a box of insulation, we might as well hire a plumber to do it. Open to any suggestions. Christmas day is supposed to be 65, and raining — go figure, only in MO. But it will turn cold again and we want to be prepared.
Thanks guys. DH not up to planning this and I'm flying blind. We can pull off the siding, reach in and wrap the pipes, then wrap with the heat tape and plug it in under the sink. At least that seems to be reasonable.
