Raised slab – insulation and vapor barrier
I have some raised slab questions.
New build in Pender County, NC.
Climate zone 3a…warm humid.
Simple rectangle envelope.
Front door facing N (slightly NE).
52’x40′ exterior frame dimensions.
Wrap around porch (front and east).
I want the aesthetics of a crawl space (raised) but without the potential issues, so I would like to build on a raised slab like this…
Pros/cons of this method? Would insulating the slab be necessary for my climate zone? If so, how should insulating be done? Rigid foam underneath like with a non-raised slab?
