I have a camp in northern Michigan that was built in the fifties. At that time the wood siding was installed on top of the studs. I am in the process of taking off the existing siding and fixing any insulation problems and installing 1/2" OSB and house wrap. I plan on putting 1" styrofoam insulation but not siding for sometime. I'm wondering what I can use to cover the styrofoam until I decide to put siding on.
