Still kinda wondering if aluminum siding would work better then foil.

Oh...I think I misunderstood the 1st time. You mean side the exterior of little doghouse. Good idea and it would look better, too.

I was just fixated on the interior for some reason.

ThankQ

Anything that makes an electrically continuous box. Screen works, if the mesh is fine enough.

it is not easy to make a good electrical connection "aluminum to aluminum," so the box/container edges, with siding, require attention.
