Question of the Day - #96 Pex to be insulated?

Postby RDavidson » Fri Dec 05, 2014 9:22 am

2015 Minnesota Residential Energy Code section R403.4.2 requires that certain hot water pipes be insulated to a minimum of R-3. A plumber tells you that PEX plastic pipe is exempt because it doesn’t conduct heat like copper does. Do you require him to insulate the pipe or not?
