Hey Fellow Builders and Consultants,
I've got a semi-unique weatherization project that I'm about to start and need some advice.
The building in question is a 24' x 24', single level, four-season cottage on piers, ranging from 3'-4' tall from grade, with a loose-fitted board skirting on 3 sides, and open on 1 side; very high and dry and well ventilated "crawlspace"......sort of.
The floor deck is 12" I-Joists with 8" fiberglass batts and 1' rigid foam rips, loosely stuffed into the joist bays. (Very leaky!)
