I have a pane of glass that has a 1" space on the inside and is 18" x 20" in size. Each side of glass is 3/16 inches thick. There are 3 layers of clear plastic inside the glass pane, each of which is 1/32" thick and are evenly spaced, allowing for 4 air gaps.
Can anyone tell me what the R-factor would be for for this space and does the R-factor exponentially increase from one air gap to the next? Or, is the R-factor equal between each of the air gaps?
Thanks for the help!
