Raised four-season room — insulation
We are remodeling a sunroom that had one supply vent. We are finishing our basement also and had hvac install another supply run and a return to sunroom. we live in St. Louis Mo. my plan 2” foam board against subfloor can foamed in place between joists. Then mineral wool insulation for a total or r30
can I also put some Tyvek on before the plywood and trim? Basically to hold everything up while I trim it.
Thank you kelli
