Are you aware, Low E is used to keep HEAT OUT is of less benefit to warm a space
Foam is always better as it has a much higher E value per inch.
And the low E glass blocks the passage of IR heat radiation.
That is most pronounced and significant from direct suns rays. It is much less useful when there simply is a temperature difference that is not due to direct sun. The Low E glass gives much more impressive results when it is a good double or triple pane.
Most of the heat loss inside to out is not due to IR but to conduction, convection and air leakage.
