Basement window wells in a foam-sheathed house
We typically design houses with continuous insulation on the exterior side of the wood sheathing, install vertical furring strips and then siding or other finished material, creating a rain screen behind the siding. We also align our rigid insulation so that it continues into the ground for our foundation rigid insulation. The question is how could we address areas of the exterior where we would have basement window wells? Would the rigid foam go into the window well, and be clad as the above grade walls are? See attached photo. We also cover the rigid insulation that is exposed at grade with an fiberglass reinforced plastic, not shown in photo.
