Hello!
I am running THERM 8.0.12.0 and I am trying to model a two-pane system. Currently, I am opening the sample-sill.THM file in the library, deleting the glazing system/spacer, and then evening out the frame cavity so it is just a horizontal line. At this point, I go to libraries to add the glazing system, but whenever I try to add the system, I do not have the option to add a spacer (photo of screen below). Please let me know if there is a way to add a spacer since I am unable to run calculations without one. Thank you!
