Clean room? Would tyvek or similar plastic barrier material make a better seal? Does this need to be so structural and permanent.

I am just thinking that drywall really doesn't lend itself to a cleanrooom situation. And, if you are not doing drywall, do you need the structure that it demands?

Sorry for the left turn. If you are making a paint room for example, there could be easier, cheaper means.

Good luck. Nice barn!
