Flooring questions

Hi guys,
I just did the flooring in the basement, and on a different forum in the midst off a question got told off for the flooring I did.

I did concrete slab, 6 mil poly, 1 inch XPS, 1/2 inch OSB.

I was planning to put floor finishings on top. However I was told that it needs to be redone or else the wood will rot.

Does what I did look that bad? Is there a way out of it short of a re-do?

Thanks

Should I consider using waterproof concrete for my foundation?

I have been looking carefully at my options for waterproofing the basement foundation of my future house in Vermont. I expect that the foundation will experience periods of hydrostatic pressure, so I am looking for the best waterproofing system with reasonable costs (e.g. up to $4000). I will, of course, install footing drains and a free draining layer on the outside of the foundation, and until recently I was planning to use a professionally applied elastomeric spray-on waterproofing product.

HPWH, HRV, bathroom vent, stove-top vent, make-up air, and balancing house ventilation

So ventilation or rather balanced ventilation seems so distant, especially when using a comprehensive ventilation strategy for all the appliances that need ventilation.

The house will be built in zone 6A, and is all electric, with PV - hoping for Net Zero.

Hardwood flooring question

Have about 3000 sq-ft area that needs to be covered. We would prefer Bazillion Cherry but not sure whether we want pre or on site finish?

Pre-finish:

Pros: Factory durable finish and the beveled edges which is what we like.

Cons: Shorter/inconsistent plank lengths

On site finish:

Pros: Longer plank lengths

Cons: Finish depends on the installer but might not be as good as pre-finish

Questions:

What finish (on site or pre-finish) and what time of surface finish (oil or water based) do you guys advice?

Would appreciate any and all feedback?

Thanks

Insulating a parallel scissor truss roof

The new side of my reno and expand project will have a 8/12 cathedral ceiling with parrallel scissor truss. I am planning R80 so 24" of batt or blown insulation in the truss space.

My question is.... since this insulation will be applied from the inside (well after the roof sheathing and then shingles are applied) how do I provide a space between the underside of the roof deck and the top of the insulation?

If one is using 3" of rigid foam (EPS) underneath a 4" slab-on-grade, does one still need to install a vapor barrier?

4" compacted AB
3" EPS (termite treated)
4" concrete

Densglass & Stucco

Can one apply EIFS or stucco directly to DenGlass or does one need to treat DensGlass like wood/OSB sheathing?

Can DensGlass be used on a soffit with it directly being applied to the OSB sheathing?

Do I need to use concrete screws for plywood over an insulated floor?

i am following your advice on using XPS on concrete basement floor followed by two layers of 1/2 inch plywood. My concrete floor is 15 yrs old will I have trouble with concrete screws in older concrete? Can I just fasten the second layer to the first layer of plywood or can I use adhesive on the first layer or do I need the concrete screws?

Laying out mini-splits for a new home

I have a new home in the design stage and have been working with with my HVAC sub and the wholesaler to layout and locate mini-splits for the project. The house will be 2550 sq.ft. on a slab with R40 walls, R75 ceiling and very tight. We are in zone 5, floor plan is attached. We will be installing an ERV for fresh air.

The HVAC guy and the wholesaler want to put a head in each bedroom as well as the entry, office, family room and great room and run them off of 2 separate outdoor units. Their concern is to provide uniform temps throughout the house.
