Avoiding cracks

We're in the early design stage for a new house in Maine, zone 6. What can we do to avoid the cracks in plaster and screw heads showing through the plaster skim coat? Using dry construction lumber should help, but would leaving the framing open for a while help or hurt?
Heidi' s recent experience with moisture in her walls in Vermont has me especially concerned.
We haven't gotten to the point where we're deciding on how to frame the walls, but any advice on heading off the problem will be appreciated.

Should I spray foam a cobblestone foundation?

The interior of my cobblestone foundation needs to be repointed. No stones are loose, but there are deep pockets in a lot of areas.

As part of a complete gut and remodel taking place this spring, several professionals have suggested that instead of repointing with mortar, that I could simply have the insulators spray the stone with foam as they are insulating the walls and ceiling.

Do 5/32" and 3/16" suffice as window panes?

Do 5/32" and 3/16" suffice as window panes? Can they affixed to each other to achieve greater thickness to abide by codes?

I have a bunch of 6 ft by 7 ft glass panes that are 5/32" and 3/16" inches thick, I also have shipping containers I am considering furnishing into a commercial business/cafe. Please take note I am an absolute novice in construction at almost every regard and still in the information gathering stages, so I am trying to acquire as much information as possible before I need to spend money and if I can make use of what I already own, that can save me lots.

Exposed steel beam that's causing a thermal bridge

I have a very contemporary style house that probably isn't the best for chicago's cold winters and hot summers.
There are exposed steel beams that penetrate through to the inside of the house and have cause a lot of moisture issues.
i have used closed cell spray foam on the inside of the house around the beams, but is there any way to cover the beams on the outside to further prevent thermal bridging?
the beams are both vertical and horizontal.
i've attached a picture of the house.
thanks for your help!

New wood foam!


Might not be news to all of you,
but it is the first time i read about it in this form.

Seems kind of promising in terms of base material used.
If it can be "foamed up" using co2 or other natural gases ...

If it uses a low % of material VS air once it is foamed,
it could be very very cheap to supply
( as in using a mix of many wood industry residues )

Even greener if the natural wood "glue" is used in the biding process!!

Then, what about resistance to insects and fungus ??
