Hi,
I have a question about insulation. I currently have an structure built out of 2x4's for a chicken coop.
After some reading, I found out that Fiberglass batting is not a good idea for a coop due to humidity, it can be done but it has to be done with a vapor barrier on the inside wall and it could lead to sweating.
So I've decided to go with Rigid Foam Extruded insulation panels that I will cut to fit in the gaps between the exterior Plywood siding and an interior plywood panel , so there would be a gap of 3.5in (2x4's) between exterior and interior plywood that needs to be filled.
I'm planning on using caulking and expanding foam spray to make it air tight between pink and interior siding. Or would it be better to air tight it with the exterior siding?
I've done a rough sketch:

My questions would be:
A) Is it better to leave an air gap on the exterior or the interior side of the insulation? In the image you can see there is a 0.5in air gap between the exterior siding and the insulation panels.
B) Would it be better to have the air gap between both panels? So that the blue panel is touching the exterior siding, then spacer, and then the second insulation panel touching the inner siding?
C) Would it be better to have the air gap in the interior side? That is between the pink foam and the interior plywood panel?
Im located in Quebec, in a fairly humid area in the Laurentians, and the chicken coop interior will probably have also a lot of generated humidity I imagine.
Cheers!
