Standard modern house exterior wall here would be brick veneer. That would be a brick, 0.5" chipboard/beaverboard, 9" fiberglass batting, 0.5" drywall.

Standard old house exterior wall would be "double brick". Two bricks (three for the ground floor), ~3" of crappy insulation, 0.5" wood lath, ~0.5" of horse hair and plaster.

Used to be different, but every apartment/condo built since the early 70's, units are separated by at least 4" of reinforced concrete.
