Struggling with how to use foam on walkout over Canadian shield zone 7

I'm building a walkout basement (1000 sq ft) in zone 7 (NW Ontario Canada) and have purchased 1000 sq ft EPS at 5 inches and 1000 sq ft at 1 1/2" XPS (I was told its much better to use above the XPS since its much more rigid when walking on during the pour)..
I am struggling on how to best use the foam on the walkout side (I got a great deal so I have lots of EPS and XPS)..

Conditioned crawlspace — rim joist insulation

Yes, another conditioned crawlspace question, I think this is number 3 for me. Our building permit is finally approved and construction is starting. I've talked to two different insulation contractors who do conditioned crawlspaces in my area (Coastal Virginia, zone 4). Both of them use closed cell spray foam on the foundation wall, and both leave a termite inspection gap at the top. One of them uses the spray foam on the rim joist, while the other uses fiberglass batts.

Is a rubber/foam product a good choice for flooring underlayment?

Hi, Is a recycled granulated rubber tire and high density frothed polyurethane foam product on the market the best underlayment for a 2nd story 1883 farmhouse condo with plywood on top of sub floor where I am installing solid oak hardwood (2 1/4" strips)?
I like it because it has much published technical data that I can show my neighbor in the condo below where we are both interested in sound silencing. I thank you kindly for your expert advice.

Interior French drain — wall detail

We're installing an interior french drain to address water issues. The grading slopes away from the house and all down spouts are routed 10+ feet away from the house. We have elevated radon and the french drain will be integrated into the existing sub-slab depressurization system. The walls are currently uninsulated, but I plan to insulate the walls with rigid foam in the coming months. The floor will be insulated when the basement is finished in a few years.

Does rigid foam sheathing squeak?

I had a Styrofoam cooler in my car this weekend. If it got next to anything else, it made an extremely annoying squeaky noise with every little bump. Does foam sheathing make noise when the house shifts a little from winds or other loads?

Closed-cell spray foam application in an unvented detached garage

I have two questions concerning insulating my unvented detached garage. The first applies to the walls. The second to the cathedral ceiling.

Background: I am located in the Midwest at zone 6. I am converting a 420 sq. ft. detached garage into a workshop. I will be installing a GE Zone-line AZ61H15DAB heat pump. The space is unvented and will maintain the cathedral ceiling with no attic space. I hope to keep it conditioned year round as long as the monthly electrical bill isn't astronomical. The floor is concrete. Finished surfaces will be drywall. LED shop lights will complete the space.

Thick masonry walls

I have a friend who owns a 600 yr. old stone house in northern Germany.

In the 70's, interior 2 x 4 walls were added with open cell white foam board 1" thick, no vapour barrier and 1/2 drywall.

They are experiencing mould issues at lower portions of interior walls.

Their intention is to open up the walls and seek advice on possible solutions. One thought is to install dense pack cellulose insulation in 2x4 cavities.

My concern with that is temp change in winter could affect integrity of mortar(stone wall) at some point in its cross section.
