Interior walls & ceiling.

[CatoRockwell]

I am looking at options for finishing our interior walls & ceiling.

We have rigid foam

insulation

already installed, & our plan for preventing

moisture

issues is an ERV system. We are looking for a a material to finish & enclose the walls & ceiling.

My wife hates drywall, so that option is off the table for us. We were looking at tongue & groove pine, but I can't find anything online about whether it will be flexible enough to curve along the walls.

For the ceiling our plan was corkboard.

With the ERV system I'm hoping that the forced air change will prevent any mold issues, but I'm open to feedback on that. My big question is, will tongue & groove work or do we need to look at some other kind of walling option?
