Comment on 2x2 lumber at Home Depot is now 1.28x1.28. Nominal size is supposed to be 1.5

That was one example, you can also strap roofs to install sheet metal cladding. Is that not structural?

I figured if I gave you a real world example you could do a little research of your own.

No, that’s not structural since the furring strips are not integral to load bearing capacity of the structure.

In your sheet metal example, they are only there for visual reasons - to help keep the roof flat. The roof can be put down without the furring strips. It might bend, but it still function as a roof.

  What…? Roof trusses go parallel with the length of the cladding panel, you require furring strips on the perpendicular to install them. Just like in a wall with the studs vertical, you need horizontal furring to install them.

  Furring strips are not visual lmfao. They are structural components in a lot of assemblies.

    Those aren’t furring strips in that photo. That’s dimensional lumber. In this case, those spans are large enough that they require the strength of actual lumber.

    Yes I literally just explained that in detail in the comment you responded to……
