Subsurface rigid insulation and boring critters
I was speaking with my passive house consultant the other week, and she expressed concerns about boring critters and subsurface rigid insulation. She had such an experience with some insulation in her garden (It was put in one season and removed at a later time as she got back to completing the project.)
Now, I know all about the ate/termite protection used in these insulation products, but what about larger critters that would love to have a warm dry home?
My consultant is thinking that having a concrete porch extending beyond the sub-surface insulation (of a frost protected slab may help - maybe having the insulation encased with gravel beneath the porch?
Or is this just a non-issue?
I would think that a area that doesn't freeze would be quite attractive to mice/groundhogs/moles etc.
