I found this tutorial (PDF) about how to make the Type 56 Library. It's old, using WINDOW 5, but the basic steps still apply to WINDOW 7 as making glazing systems and windows has remained pretty much the same.
Basically, you need to generate a DOE-2 report from the window library, and then get the information from that report into the format for the Type 56 window library.
The WINDOW 7 User Manual, found on the WINDOW documentation page, has information about the format of the DOE-2 report on page 7-25
Here is a direct link to the manual
