Ice and Water Shield on Walls?
I live in northen NH. My home has a stepped foundation which puts some of it within 2-4 inches from the ground on the eve side. It has a steel roof and no gutters so rain splash soaks the walls. My builder put I&W on the first three feet of the walls to combat the soaking that can happen from snow build up and splashing against the vinyl siding. If I make sure I allow drying to the inside of the walk in basement, and keep humidity in check, will I be ok? Or am I asking for rot from dew point? I can’t see how it could rot with not much air between the I&W and the outside sheathing… Foamboad on the outside is not an option which is too bad.. I do have 2in on the gables.
