I dug out my crawlspace one bucket at a time over a few winters to achieve 2 feet or wiggle room. I then installed R29 batts of insulation and held in place with tinfoil foam board using large washers and screws. I then spray foamed every seam, cut and taped it all with aluminium tape. My 1910 house is now greatly more comfortable and now even renewably powered with electric heated floor slabs.

Its a bit late but insulation only works properly when all 6 surfaces are touching framing or osb etc. as you have not filled the cavity, air will circulate ( convection ) in the space and so will much reduce the R value, filling the cavity reduces air movement and thus allows the fibre glass to work up to spec. Its like down or most other products it works by trapping small pockets of air/ gas. Also ridged expanded polystyrene Would work better as it would form a thermal bridge, the foam board should be glued and screewed to the frae to stop air infiltration. Assuming there is a path for humidity to move upward through the floor there should be no mold issues

Use an air permeable membrane, like the stuff they sell to put under roof tiles. put it higher, half way up the beam so that it is up touching the floor timber then it will not have a hot void.

Trying to insulate for a colder climate, use a vapor barrier and keep the rodents out. Not quite sure how to do all this from above. If we close up the foundation by pinning the ledge and pouring a footing, we no longer have access for any plumbing repairs for the kitchen as there isn't enough room for a crawl space.

I had to stick my phone under the house and make a video to even see it as my clearance is only 6 inches (don’t even get me started on that). After spending $500-600 on brand new R30….Guess what? Critters sure enough have pulled parts of it down, made themselves a home and now I’m having to take out the subfloor and redo this whole mess! USE HARDWARE CLOTH! It’s easy to do it from the top! You can still do the tyvek and that will help work as a barrier that also will allow the insulation to breathe. Or just use rigid foam! Either way, please do not do this without something protecting it from being pulled down! You’ll regret it, more than you even know.

Don't know if this is too late, but an animal could eventually tear through the housewrap though it is rather tough and may keep them from seeing the insulation (especially if you tape the joints with Tyvek tape).

I'm certainly no expert on the matter, but I know that housewrap is specifically designed to be breathable from the inside (side with no writing) to the outside. If you think about a normal wall with gypsum on one side sealed and caulked and osb on the other side with housewrap and then siding sealed and caulked, this would also technically be insulation sandwiched between two vapor barriers (housewrap on the outside and paper facing of the insulation on the inside). My thoughts were that the breathability of the housewrap provides enough air circulation for the insulation to breathe just like there is enough air in normal walls to keep mold from growing.

You could even apply a simple spray of diluted clorox first all around to knock down the spores. Lay down the barrier, and then apply this method-- with positive ventilation to keep that crawl space circulating dryer air. Real dilemma you have raised with no vapor barrier. Hmmm.

In principle, there's really no difference between the floor application and the way insulation is sandwiched between sheathing and vapor barriers in typical wall. However, the crawlspace itself needs to be properly ventilated. Regarding being tight against plywood, i don't think so. There are many applications where an air space is a critical part of the insulation. In this case, I'm not sure if it adds any r-value, but as long as the insulation is fitted well, i don't believe not being tight against the floor will make any substantial difference.

Having an air space between the insulation and underside of the plywood can even be an advantage. One can create a radiant barrier by (1) using insulation with a radiant barrier foil on one side and (2) placing the insulation so that the foil faces the air space and underside of the plywood. More generally one should consider how super heated air would flow through air spaces in case of a fire, particularly inside a wall cavity.

But isn't that a moisture barrier ?? A moisture barrier is to be used under the floor itself, which allows the insulation to breath. (you never moisture barrier the outer edge (cold edge) of an insulated area) By putting moisture barrier on the bottom - you are inviting moisture to form and saturate your insulation. Might look neat and clean - but it's going to promote rotting / mold, along with inviting rodents to chew through it to enter the "plushy" insulation. This will work for a year or two before you notice molding and critter infestation . The proper way would have been to line the bottom with foam board all the way across. It would not only stop the moisture worries, but rodents tend to avoid foam board and as a triple advantage - - By covering the bottoms of the floor joists - you would be eliminating thermal bridge loss through the joists. Top off a great job with the foil lined "bubble wrap" between the top of your floor joists and the top floor covering. Bridging would be completely blocked and the foil lined bubble wrap serves as the moisture barrier which you SHOUL apply on the area facing the warmed / cooled area (not the outdoor area Noce Idea - Just too bad you created more headaches for yourself down the road
