* "Woven" indicates normal batts of the indicated type, installed so they weave around the studs. Near the studs, they are compressed between the stud and the adjacent gypsum board, as shown in the figure at right.

Batts of insulation not described as "woven" were installed in the inter-stud cavities as shown here. Note that most batts are compressed to some degree between studs and the gypsum board on the opposite face.
