I 'm designing a new apartment project with raised poured-in-place concrete planters immediately adjacent to the wood-framed exterior wall of the apartment.
I first thought about simply building the wood apartment wall on top of he planter stem wall, but then I would need to furr-out on the inside of the bedroom for insulation, losing valuable floor space.
I'm not looking at doing a double-wall, where the wood-framed apartment wall extends down to slab-on-grade, and there is a second, separate raised planter wall next to it.
Question: years ago I remember something in the code saying I had to separate these 2 walls with a 2" air gap. Is that still in the code?
All I could find was a requirement in IBC 2304.12.1.3 to keep untreated wood walls out of "direct contact" with the raised concrete planter, with no specific gap measurement mentioned:
