Au contraire, you'll get another US R1, or perhaps more, with low-e.


okay i can go with that...

If 250 Btu/h-ft^2 (full sun) were to hit the storm window (unlikely, given
the angles involved) on a 30 F day and the window passed 225 and the screen
absorbed 20% of that, ie 45 Btu/ft^2, and that heat moved to the outdoors
via an R1 storm with no air leaks and to 70 F indoor air via an R2 window,
the net heatflow out of the storm window would be (70+45xR0.5-30)/(R1+R0.5)
= 42 Btu/h-ft^2, so the temperature near the screen would be 30+42xR1 = 72 F.



Nick, not sure what this has to do with a storm window harboring heat and
warping vinyl jambliners, but thanks?
