Hi all planning to run copper pipe through stud wall to feed a new shower in the bathroom. Question is how can I reduce the chances of condensation building up in the stud wall from the cold copper pipe ? Using copper as not a big fan of the plastic stuff. Going to use sound proof  insulation in the stud wall as it will back on to the now small box room.is there a chance this can get damp from contact with the cold pipe it's the wool type I am going to use . many thanks Jason. 

Insulate pipework with climaflex 

I veed the Celotex where the pipes run in my walls. Then foamed and fitted the top section of the V back in. Foil taped over the top.
