I want to insulate my hot and cold water lines. They are exposed in my basement, so there is easy access. I have seen the 6 foot foam with both 3/8" and 1/2" walls, and I have seen fiberglass strips 3" x 25'. I like the foam idea, but wonder about the added thickness being worth twice as much, and if the fiberglass would be better than the foam.
