Re: Anyone use EPS rigid foam insulation in their floor, between the joists?
Installing sheathing under yurt deck framing? Just an educated guess but I've never seen sheathing under floor framing in 41 years of carpentry.
It's not likely anyone would make the effort to sheath the bottom of a floor frame, but in case someone gets the idea to attempt it, consider that fabric covered yurts have the potential to leak, especially in wet climates. Water and water vapor that can't evaporate and pools on the sheathing installed to the bottom of the floor framing could potentially trap alot of over time. Mold rot termite damage to the floor frame could ensue as time goes by, especially in wetter climates.
Sheathed walls and roofs is different than flat below the floor. In particular under bath and kitchen I'm thinking isn't such a red hot idea. I've done extensive repairs to the framing below the baths and kitchen in my sister in laws house in CA from serious termite action, mold and rot due to the foundation not breathing.
