Gents, so i am at the point whilst waiting for concrete that I need to get cracking on insulation, in order to start sheathing before it gets too cold here in TN.
I have been kicking around a few ideas for insulation, I don't need it to hold heat in like my house, however I would like a little something more than bare metal inside the walls.
I am planning on sheathing with sanded plywood in order to hang things up in any place that I choose once the building is complete. i am also planning on running all of my electrical in exposed conduit on the walls in order to facilitate changes in the future if I see fit.
The builders did not insulate the walls with the double bubble insulation on the exterior and recommends that I use rolled batts in between the studs in order to insulate.
My issue with this is that I am already planning on rolling out the red carpet for mice and other pests as I live in the woods. I have seen rodents turn rolled fiberglass insulation into 5 star resorts before and would like to avoid that scenario.
Spray foam is out of the question as it costs $1000 more than my concrete quote on the low end. So that leaves me with foam board insulation.
I was considering 1 of 2 options.
1. Using GAF POLYISO 0.5" thick foam board insulation between the studs and securing it to the metal with liquid nails then sealing up the gaps and cracks with DIY spray foam. I have heard great things about this product, based on its minimal thickness it provides an R-value of 3.6 at its 0.5" thickness which is pretty good for its size.
2. Using the same product, but sheathing the entire interior of the building, taping the joints and then sheathing over the insulation board with sanded plywood. That would leave a 6" gap between the metal and the insulation board to allow air flow, however I wonder if this will be too much airflow and eventually cause moisture to build up in between the walls.
I would really prefer to not use rolled fiberglass due to previous rodent experiences, however I would consider it if anyone has better suggestions on how to manage critters getting in the walls.
Would either of these options be better than the other or would both of them be about the same as not insulating at all? Like I said, I realize that the R-value of 3.6 isn't that much, but I will have a wood stove in the building for the winter and potentially an AC unit for the summer eventually.
The biggest reason for wanting to use this product is because I already have about 1500 square feet on hand from a previous siding project.
As you can see by the pictures below, the building has been studded out horizontally between the posts.
Thanks!
