Peel & stick - Under or over the strapping

I'm in the process of building a thick foam covered wood framed house.
It's a 2x6 wall with 2.5" of XPS, followed with 1.5" of polyiso foil faced and taped. In order for me to apply my vinyl siding i need to add 1x4 strapping and 2x10 windowbucks as the foam is so thick

I'm uncertain on whether of not to put the peel and stick membane over the 1x4 strapping or under?
My windows are new contruction and have nailing flanges

I have included a picture of what is going on... if i go over the 1x4

What is the perferred way to ventilate a basement?

I built a house in VT zone 6A. The unfinished basement has a musty smell to it. The 2 floors of living space are fine.

I only have 2 (1'x2') basement windows in the east side of the house. I'm planning on finishing the basement and looking to install a HRV ventilator for the basement only. The house is heated with radiant floor heat and wood stove. Basement is 1,400 sq ft.

Why would there be 2 air returns in a bedroom with only 1 supply?

I recently purchased a tri-level home built in 1962. It hasn't seen a lot of love over the years so I'm trying to make some cosmetic improvements before moving in. In each of the 3 bedrooms there are 2 air returns, one near the floor and the other directly above it about 6 feet up, on the wall opposite the supply registers. For aesthetic reasons I would like to close off the upper returns but hesitate to do so without understanding why there are 2 of them and is closing one an OK thing to do. Any advice would be appreciated.

Will this insulation assembly work?

I have a situation and I was wondering if I could get some input on an assembly I may be doing. Please refer to the PDF drawing I have attached to this. it will explain a lot more than words can. I am in Washington State in Marine Climate 4. I am working on a remodel of my house.
I realize there are many better ways that this assembly could be done, but that isn't what my questions are about.

Does anyone know anything about "Smart Foam" used for insulating walls and attics?

There is a company out of Nebraska that claims smart foam has an R value of 10 and is the best for attics and walls.

What are the effective options to insulate existing walls?

If this question has been answered please point the link - I am unable to find past material.

The home is over 50 years old. The wall cross section is: brick veneer, cavity, celotex type material, framing, and plaster on board inside. There is no other insulation material in the wall cavity between the celotex and the plaster.

The blown in insulation folks say they are the best option. The injection foam folks say they are the best in R value and performance - that the blown in settles over time and that it does not control air movement enough. Of course the foam is more expensive.
