Assembly for bonus room floor
I’m looking for advice on insulating the floor of a bonus room in Vermont that is currently not insulated. The bottom of the joists are around 6 feet off the ground, so the common advice from top to bottom would normally be: flooring, subfloor, joists and bat insulation, foam board, and then plywood. I’m looking to minimize costs (and foam) and I’m wondering if strips of foam and strapping furring out the bottom of the floor joists would work instead of a continuous layer of foam – in theory this should create nearly the same thermal break?
