We’re building a 3-season sunroom and don’t plan to heat it in the near future.

It’s been suggested that we insulate the interior now – while the walls are open- to make future conversion to a 4-season space easier (e.g., adding heat and upgrading windows later). We’ve already installed 2″ of exterior foam with this in mind. We plan to finish the interior with wood tongue and groove paneling.

Would insulating the walls now, without heating or cooling the space, potentially cause moisture or durability issues?
