Help Please

Question?
What is aerofoil and where do you get it?
can someone help me as I am using a survival blanket but heard that aero foil is the way to go.

you mean mylar? High Tech Garden Supply

if that's too rich for your blood, than you can get the cheap silvery wrapping paper that has a silver backing. supposedly it is made out of mylar, but from what i've seen it will work pretty good.

Panda Film is the way to go IMHO.... Good strong material, that is white on one side and black on the other. The White side reflects 95% of the light, where as the black side obsorbs 100% of the light. This is good stuff. I built my room out of it and some stick framing. Most hydro Stores sell it.
