A very weird pic, no? If you look at the far end, those strips look

like furring strips or similar. If you look at the near ends, they

morph into somthing flat and thin vertically.



Nope, not a great architectural drawing granted, but they're just cut at

a diagonal at near end, at least on the rendition here...the vertical

thickness still shows at the front edge, just the rear along the slice

is hidden...


Not what I see here. The far end laying on the joist does look like strips
one could use and they look wider than they are tall. At the near end,
they are tall, thin, little thickess, more like strips of sheet metal standing vertically.
