The R value of reflectix is dependent on usage. This is a better discussion:
It is very good for radiant heat loss but not so good at conductive. I'd rather have a CCF pad between me and the ground but a reflective bad behind me facing a fire. OTOH we often run into a basic issue of how much is enough. Often the answer is "not much" so most answers work OK. Now a reflective CCF pad would be interesting...
I don't know. I've spent well over my due time on a PT mat on cold concrete or dirt. It doesn't make me warm, but I don't feel the cold.
This past weekend, lounging on my reflectix pad, I could feel the mylar radiating heat where I was contacting the pad. This was the 3rd trip this particular piece has been on so it's not as nice as it first felt, but at least it lays flat now.
On our Ohio Hang people were trying it out, ground was frozen, butts were WARM. I trust it's conductive efficacy.
