Reflective Barrier, in a crawlspace?!?

Living in Idaho, I have a relatively large house, and I am installing a reflective barrier in the crawlspace for some additional heat savings. What is the total heat to be saved from such an endeavor, and any tips would be handy to have.

thanks, ;)blue

Howdy, Do not do it- save the money what are you hoping to reflect heat rises. To insulate the floor add un faced R22 fiberglass batt insulation it allows moisture to escape. If no plastic on the dirt add 6 mill overlap seams 10 inches and run bead of caulk at the overlap.
