We’re working on a remodel and I have a handful questions:
1. The house has a florida room on slab that is 15″ below the main level floor. We are finishing the room as living space and framing the floor over slab to be flush with the main level. If I lay a vapor barrier over the slab can I throw loose fill cellulose over the slab and in between joists to insulate the new floor?
2.) The exterior walls are 2×4 with brick. We are adding 2″ of faced rigid foam to the interior with taped seams as air barrier/thermal break. Any recommendations for a tape or caulk to seal the rigid foam to the subfloor?
3.) We gutted the basement and are considering adding rigid foam over the slab. Do we frame partition walls before or after the foam over slab?
4.) We’re building a detached garage on a frost protected mono pour slab. Should the slab be sloped or is flat okay?
