Securing it when laid on the chord isn’t as easy to do. Staying below the vapour barrier is something else you may want to consider (oops…vapor).

We're looking at a redo of a 13D that had CPVC in the unsprinklered trussed attic space under the insulation but above the bottom chord. OK or not? I've read the manufacture's pamphlets - and well, depending on which eye you want to close...
