Pucks were used to float the floor only with insulation between the 2x4s. Let me know if your opinions change or if this is still recommended against. I was wanting to apply this to walls, not the floor. I'm taking Rick's advice on leaving the floor as an isolated slab, I just need to apply a parge coat of mortar when the shell is done to give a finish floor effect to the slab.
Yeah....sorry. I'll actually start a new one to reflect where I am currently with the exterior leaf. A lot to learn and I get a little carried away. Sorry for posting on your thread Wag.
