Even with spray-glue and cardboard there will still be "hot-spots" if you use Mylar, or any flat foil.

I highly recommend Reflectix insulation.

It's about as stiff as good cardboard.
Very lightweight and easy to work with.
The surface is "bubbleized" to prevent hot-spots.
It reflects 97% of full spectrum from both sides. (excellent insulator).
Relatively inexpensive. A 4' X 25' X 5/16" roll runs about $50.

I love this stuff. Am using a panel of it outdoors. to reflect sunlight. (Try that with Mylar!)

Lined a small, 2' X 3', air-conditioned room where I ferment wine and have to hold the temp at 68 degrees F. 24/7.
Ambient is about 82 F.
With the Reflectix installed it only eats 1.14 Kwh. per day to hold 48 cubic feet to + or - 1 degree F.!

We pay $.44 per Kwh. here.
(:cursingon't get me started)

So that's about Fiddy Cent per day or $15 per month!
A bit more than a good refrigerator of that size, but not by much.:thumbsup:

Put away the glue and cardboard, Shove', the future is now!
