Foam insulation wrap question

[BobbyJoe]

Hi everyone,

I have bare pipes under the kitchen sink and also in a cupboard next to my bathroom. Is it a good idea to put foam wrap on them and if so should the wrap be on both hot and cold water pipes or just the hot water pipes?

Thank you any advice would be appreciated.

always good to keep cold, cold. and hot, hot. so nothing lost in doing it.
