Wood accent wall
Sean Cotter| Posted inGreen Products and Materialson
Zone 5b. Spokane wa. concrete foundation walls. 2″ of xps, framing with roxul. planning for drywall but would like to have one or two wood accent walls on ext surface. what would be a suitable surface behind the wood planks? the boards will be spaced slightly to give some shiplap look to them. Something black would be best. would like to avoid both drywall and the planks. would 60 min paper work? Maybe a roofing tar paper? inspector has ok’d the assembly with just planks and no drywall and no vapor barrier along the drywall only sections.

Sorry for the truncated, misspelled, anti-grammer original post. I had forgotten the detachable keyboard for my MS Surface and the touch-type on screen keyboard was not my friend.
At any rate, we'll probably be doing the Japanese shou sugi ban technique on some big box (cheap) cedar planks to give ourselves a cool looking accent wall. Potentially butted right next to each other, but perhaps with a small gap between them to give it some dimension. The roofing paper/building paper would do double duty - protect the insulation while we finish the rest of the space and install the accent wall planks and also be a black/infinity background behind the planks. Does this seem reasonable? I found all the '60 minute' paper I needed for less than $13, thicker roofing material was a bit more (more chemicals, perhaps?).
Thanks for any insight.

Sean,
I always like to see an air barrier between air-permeable insulation and the interior of a home, but I have to admit that in your case, the air barrier isn't strictly necessary (although it might discourage mice).
The inexpensive way to go is to install asphalt felt or building paper, as you propose.
If money is no object, you could install a WRB / air barrier product intended for use behind gapped siding; I'm thinking of Cosella-Dörken’s Delta Fassade S. (For more on this product, seeNew Green Building Products — September 2010.)
As always, thanks for the info, Martin. I'll check out the WRB.
