I have an engineered sunroom kit being installed. It is all glass and aluminum, being installed either on an existing slab (if found to be suitable) or a new fdtn. It is a thermally isolated room. How do these rooms meet the energy requirements for wall and floor? The code allows a reduction to r19 for the roof/ceiling (zone 4, 2006 IRC) but maintains r19 for the walls and doesn't address the floor/fdtn. It will be conditioned by a mini-split. How can an all glass wall meet r13 or is it satisfied if the glass is all U factor .50? The plans don't answer any of this.
