Cork insulation as finished facade
anybody out there have experience with the expanded cork insulation out there? here’s my situation: the higher density facade grade cork is just too expensive to make it work for my application. the standard grade would work, but it’s not recommended as a facade. the cork in question would be used as insulation + facade (no siding), but would be in a very low-exposure area, and subject to less weather extremes (it’s under a covered area).
i’m trying to get the ‘coolness’ of cork, plus like the idea of needing less siding material.
any thoughts?
thanks!

i should make it clear: i'm trying to figure out if using the lower density material would be folly? otherwise i'm going back to mineral wool + furred-out wood siding
Jonathan,
Have you read these GBA articles on cork insulation?

Jonathan,
I don't recommend using cork insulation as a siding material (exposed) unless it has been rated as suitable for a facade.
i've read those articles, thanks. it seems, then, that cork is now out of my range. at >$2.60/bf, it just doesn't make sense on this project... oh well.
