Default 1/2 inch white Stryfoam vs single pane

Styrofoam results

On one side of the window's half section the Glass was left exposed.
The other window's half was covered with 1/2" thick Styrofoam sheet 2'x3ft. top to bottom.

Test #1
Bare single pane glass - 54*

(1 sheet ) Styrofoam - 63.2*

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Test #2

I added one more sheet of Styrofoam, for a total of 1 inch thickness.

Bare single pane glass - 53.2*

(2 sheet) Styrofoam - 63.3*

Outdoor Temp was 31* in both tests

About a 10 dgree improvement.
Strange there was no gain from the 2nd sheet of Styrofoam, I double checked the Data.
