"After having seen several problems like this - here is my recommendation. You can try what ever you think is appropriate. Use the Armaflex (or similar) everywhere you can. Make sure you air/vapor seal all seams and joints. I would use a mastic and…"

"Just a follow up to Mark's post "cold waterlines in this space wont be exposed to outside humidity" I am actually more worried about the indoor summer time humidity.  Typical indoor conditions will be somewhere in the 50% -60%…"

"@Sean, by closed cell foam noddles, I think Mark is referring to the Armaflex or similar. I'm guessing he missed in your original post that that's what you're planning to use."

"Thanks for reply Mark - appreciate the follow up. Most of the piping will be routed through interior walls, so the VB would not be present. I am generally running continuous PEX lines from manifold to fixture stops, so will not have hidden…"

"Expanding spray foam in a can and also the closed cell foam "noodles" are options I didn't see mentioned. If your floor joist s are properly insulated & sealed off with a vapor barrier, cold waterlines in this space wont be…"

"Realized the comment above did not make total sense.  Of course our outside dew cycles has nothing to do with interior pipe insulation.  But yes we do have pipe condensation issues.  Cold water lines (incoming temp 40F-50F) are below…"

"Hi David,  Thanks for follow up. It is becoming common to insulate the cold lines to prevent condensation now that most new construction turns basements into living space.  We have a LOT of dew cycles in our climate (probably thousands a…"

David Butler replied to Sean Wiens's discussion Insulating Chilled/Cold Water Lines
"The wood itself provides some resistance (about R-1.25 per inch for a typical stud) so you just need to butt and seal the insulation tubes to the stud face. Injecting foam into the seam seems like overkill. I would just overdrill the penetration…"

"Thanks Sean - I do not have 'wet walls' most places I will be installing the supply tubes.  So definitely cannot drill holes larger enough to allow continuous insulation in the 2x4 sticks. And even a 2x6 would not be allowed by code…"

Sean Lintow Sr replied to Sean Wiens's discussion Insulating Chilled/Cold Water Lines
"It's called a wet wall - in this case it should be at least 2x6/8 or even 2 2x4 walls with a gap in center to run all the branches up then hopefully through scissor trusses or I-Joists (which you can drill out that large) Now you can drill out…"

Insulating Chilled/Cold Water Lines

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…See More
