Properly set. The dialogue about if the emissions affiliated with insulation creation are truly worth it ought to be framed being a comparison to other insulation styles, not as being a comparison for the straw-man of not utilizing insulation or working with far too little insulation.
Justin, Note that the Tyvek making wrap serves as our water-resistant barrier (WRB) and is also the base layer of the rain display structure - a driving wind blown rain could get to this area & gravity movement to the base on the constructing.
Nearly anything can be done, which include your advised technique of eliminating poly. It really is just an amazing volume of work. I wouldn't propose executing it unless there were other good reasons to remove the prevailing sheathing.

It's not at all only fireproof but in addition protects the constructing by decreasing heat transfer along with the spread of fire in just framing cavities.
Roxul, especially, likes to develop these overall "rooms" product of rigid Safe'N'Seem batts at trade displays only to demonstrate how nicely they operate... but certainly, you would by no means go away the batts like that in the actual entire world.
This looks like it would reduce the exposure of froth to bugs when you’ve completed an excellent position encapsulating. [Certain dilemma: does the insulation must go onto the crawlspace wall initial, ahead of the vapor barrier? I understand some encapsulation corporations make this happen, but on poured partitions.

In NYC for many years EIFS programs have been banned by regulation - as a result of check here thick choking, blinding and toxic smoke made whenever a setting up burns - and the risk it posed to fireplace fighters. The challenges remain, as does much of your ban. Isn't really a DER with 4 levels of overlapped foam just another EIFS method, While using the identical humidity trapping / wood rotting background.
So now I am considering seriously about both the “breathable dwelling wrap” and “clever vapor retarder” references you elevated. I'm attaching various sketches and pics that will help point out the challenge places I would like to address:
