 Um, so what I would do nowadays, I think if I was doing a basement, I'd probably get the same batting insulation, you know, with the paper face, I'd staple that right on the, uh, uh, the, the, the studs of that wall. And then I'd take a box knife and I'd slice through the paper, um, and break down that vapor barrier. And, uh, that's what I'd use for insulation.
