Steve,

That is really a great idea.

I guess the main reason against it is that I am living in the house, and the bathroom (a mini wet room) and kitchen, both of which I use multiple times a day, are in that space.

Having construction going on in your own domicile is very disruptive, as I'm sure you and your wife know all too well. As it is, I have several big projects going on right now in my home, and I struggle to hang on to some modest assurance that I am still participating in 'civilized life'.

Also, my current plan and future plans for the kitchen space, are based on having easy access to the under-side of the kitchen floor.

I don't think I'll act on your idea, but it really is a great idea.

If your idea had been presented to me at the outset, I think I would have gone for it in a heart beat.

Thanks for the suggestion.

-AC

Thermal bridging visualized

There is also cold air washdown caused by this thermal bypass problem in the image below from the attic that I have since fixed using rigid foam which was spray foamed in place to stop the air and then covered with loose fill cellulose. The fiberglass insulation not being encapsulated is also an issue. I'm going to build out the framing to expand the cavity to about 10.5" thick and use insulweb and dense pack cellulose to get that space air tight and get to almost R40.

She reminds me regularly! I don't even notice the mising plasterboard or piles of tools anymore.
My parents always had a renovation project (that we lived in) on the go as I grew up so for me the idea of living in as finished house is novel.

However our son will soon be mobile so I need to get in the habit of having a safe and clean environment for him.

Steve,

Sounds very familiar.

When my girlfriend comes to visit my 'construction zone', she fears for the safety of her dog!

Water causes more damage in homes than all other things combined.

Never have 2 moisture barriers in the same wall, floor, ceiling, build-up.

A/C cool relics, your plastic down on earth should work fine.

On the log sub-floor underside, Closed cell spray foam thick enough to be a moisture barrier (3") $$$ IF THERE IS NO OTHER MOISTURE BARRIER

Things are progressing nicely in the crawlspace..



Foam panels are going into place, with spacings as close to 1/4" as irregularly-installed floor joists will allow.



I can start foaming in the gaps as we go.

I don't believe the fanfold insulation is thick enough to qualify as an air barrier, but there are foil faced products in fanfold and in a thin roil that would work if they are not punctured

Default Foam Sealing - Part 1

The foam board is progressing.

We are starting to use foam-in-can to seal the seams.


It is difficult working overhead, and getting an adequate seal without waste.


The excess I'm not too worried about as it can be trimmed after it sets up.

However, I'm sure there will be gaps, however and they need to be found and filled.

We are also finding voids and gaps around the edges of the foundation, which will take foam and creativity to fix.

Best,

-AC
