Details on layer composition: Walls, Roofs, and Floors

[amaccarini]

Hi,
I am trying to better understand the layer composition of the different constructions listed. For instance, in the file Insulation Wall.tsv, I see options such as Option=Wood Stud, R-15, Option=CMU, 6-in Hollow, R-19 and Option=Brick, 12-in, 3-wythe, R-7 among others. However, what exactly do these names mean? Is there any documentation that provides details about the thickness and composition of each layer?

Take, for example, Option=Brick, 12-in, 3-wythe, R-7. According to the documentation, this wall has a total thermal resistance of 10.3 h-ft²-°F/Btu. But how is this resistance achieved? How many inches of brick material and insulation are included? Is it possible to find more detailed information about the layer breakdown for these constructions?
