I would support it more often then every 32 inches, but that's just

I am also curious about the double insulation??

Very simple really,

Use the 4 ft foam insulation sticks from home depot. Then wrap
that with 3 1/2 " fiberglass wall insulation in a spiral, and finally
wrap clear plastic (loosely so as not to over compress the fiberglass)
around that to hold it all together.

Water sitting in the pipe stays hot/warm for hours after a shower.
