Ventless (sealed) crawlspace
Anyone have personal experience with the pros and cons of a ventless crawlspace?
We're a few days from breaking ground on our next new home, so I've been doing considerable research on this topic.
Prior new construction has been vented crawlspace or full basement, this house will have a "stoop-over" crawlspace.
Here, in western North Carolina, the trend for "knowledgeable" construction is towards ventless, with two techniques, either sprayed-on foam or a combination of 10 mil plastic vapor barrier and ridged insulation.
Here are a few sites to explain the procedure (not my endorsement, merely for illustration)
what are your thoughts?
