We are building a house in Hanover, N.H.
Based on discussions from GBA, we are adding 2 1/2" XPS to the exterior of the sheathing. What is not clear is what (if any) treatment occurs near the ground level -- i.e., on the bottom edge of the 4x8' panel of XPS.
If left exposed, is it susceptible to rodents, bee nests, etc? The siding will be Hardiboard.
