Supplys for a basement shower are in the same joist cavity as HVAC run. They also travel a short distance on the warm side of exterior wall (though wall is to R12 insulated ). I have wrapped the majority of the copper with insulating sleves however there is some portions of the pipe that is flush with the joist hence the sleve wont fit....Could I simply spray these sections with a canned spray foam such as Dow Great Stuff. My logic would be to guard against any possibilty of a pipe freezing and in the summer months to avoid any condesation isssues with the pipes that share the same cavity as the HVAC run.
