#Poly bridge 2 double duty full

I will never live in a house without a full slab for this reason, in my opinion its a comfort game changer.

So much of my walls are glass anyway, especially on the south, are you really going to feel the 1 degree cooler drywall when there is a 9' wall of glass 3 feet away? A tight house facing south with proper glazing will be 87F inside with windows open on any day above 10F. Design sacrifices are made for northern glass, extra sf, not a perfect rectangular layout, etc, etc. I would also think a thicker wall assembly makes even more sense if you're really going all in. To be clear, I still think continuous exterior makes a lot of sense but I'm not building passive houses. I guess its a question of how warm exterior foam is really keeping your walls. I don't think it would be that much less work than continuous though I suppose it would use a lot less foam. I've seen the method you linked to in the past.

Thing is, my county is now requiring R22 walls which means either source the silly stuff labeled R22 that you stuff and compress into the wall or do 1' of ISO on the exterior to get to somewhere between R24 and R27 depending on who you ask. I am the labor and I could easily wrap this house with 1' in a day. Labor or learning curve is not a problem for me. I think those are the things that matter most. Both buildings had heavy roof insulation, air tight details and were sited correctly with intentional landscape. All you can do is watch how the building performs at different seasons. But like I've said, I've lived in houses I've built with 3' of foam and others with no foam and the difference in comfort was minimal.I think. I'm not completely trying to be a smart ass here but it is easy to get caught up in the science of all this, I know and I have. Too much, better for your ego than your comfort level. I believe there may be a sweet spot in each climate zone. So the question starts to be, why even do 1'? Go big or go home may apply when it comes to continuous insulation.but don't go too big because that's a waste too. I've already done that so I guess I'll buy a second swing for the dungeon? Maybe there are some test out there that show these progressions but my good ol gut tells me that you'd need at least double that to start noticing the performance outside of a few pennies of savings on your electric bill. For example, you'd probably be better off putting the money toward fatter windows to feel less radiating cold/drafts as opposed to 1' of foam. My point is, there must be a minimum thickness of foam in an extremely air tight structure where the comfort level goes up and I don't think the minimum allowable amount of 1' is really going to do that. For example, if I build a sex dungeon with the savings, is that going to help me figure out if 1' of continuous insulation is really making a difference in comfort in an air tight building? Assuming all the low hanging fruit has been picked and licked in the new dungeon, exterior foam shows up to the party. I don't think it matters at all what the money would go to.
