NFRC now has a procedure for adding applied films to substrates in Optics5 and importing those applied film constructions into WINDOW5 to be used in a whole product calculation.
The information presented below is provided to help simulators with this process. Feel free to contact us at [email protected] with questions or comments.

Bug with Coated Substrates
In Optics 5 (version 5.1 Maintenance Pack 2) the program does not calculate the correct results for applied films on coated substrates -- it calculates the same result as the applied film on a non-coated substrate.
Example:
Uncoated substrate with Applied Film:
Layer #1 = CLEAR-3.LOF
Add Applied Film = Southwall VK75.swt (V-Kool 75)
Coated substrate with Applied Film:
Layer #2 = LOW-E_3.LOF
Add Applied Film = Southwall VK75.swt (V-Kool 75).
All the Transmittance and Reflectance values are identical for both new layers, which is not correct.
