Insulating cold and chilled water lines in dwelling - Best Practice?
Good day folks,
I am wondering what best practice is for insulating chilled and cold water pipes inside a dwelling regards to protecting from condensation.
I will have both domestic cold and chilled space conditioning PEX circuits throughout the home.
I plan on using Armaflex continuous coil elastomeric rubber insulation (1/2" thickness) for the runs between fittings.
But what do you do at framing penetrations. Obviously I cannot drill out a 1-3/4" hole in 2x4 plates and studs, so what is best practice to seal at these points to prevent condensation?? Specifically worried about double plates or multi-ply studs.
Also, what is best practice around manifolds, valves, etc.? I have some Armaflex flat stock. Should I just make an air tight box around the device leaving things like valve handles accessible?
Any advise would be greatly appreciated.
(PS I know not to insulator circulator motors, zone actuators, end the like)
