Maybe I should have said heat conductor. If it's a moist coating on the walls,
it seems like it might conduct heat into the wall-board and the 2x4 studs inside.
I'm not sure what would happen. But, I tend to think making a wall thicker is going to give it a better R factor.
If I had Clay on the walls, it seems like I would still need to 'water' it.
Just like I'm
watering the air right now.
I guess the idea is to have this reservoir of water sitting in the walls, ready to come out,
when things starting to get dry..?. I guess it's mostly a stabilizer..
Hey, with all that water, it's going to be a
Thermomass!
It's going to hold heat from during the warm part of the day..
A temperature stabilizer too..
Might not be a bad idea for a passive solar home in NE..
I'm starting to like it!
