Answer: Instant ducts are made by capping off a section between two studs. The same thing can be done in the floor joists. Objects like gypsum boards, sheet metals are nailed with joists or cavities to make rigid pathways of return or supply. In fact there are companies that advertise their insulating sheets that can aid in such practices. You should know that using building cavities as return air plenums is one of root causes duct leakage.
