Does PEX Sweat?


Closing up a ceiling in a basement,I have only covered the existing copper pipe.
Haven't covered the newly installed PEX.
Do I have to cover it to prevent sweating,or not.
Thermal efficiency is not an issue.
Thanks in advance for useful answers

Ditto. Does it seem to be sweating now? Make sure it is not a slow leak following the path of the tubing before you encase it or whatever.

The PEX isnt sweating now,just looking to save time if additional newly installed piping didnt need it.

Covering is more of a pain on the new runs as they are laying on top of floor joist plates,but cut away I must,no sense in ruining my future sheetrock installation with water damage.

What can I say,I'm lazy as the next guy.
