I’m ready to cedar clap sides of workshop/shed. Found article re. rain screens very enligthening since I had to repair some water damaged siding on house last yr.. Since author stated use of core-a-vent as means for air flow channel, and used to “stabilize” water table bd. could this also be used as the vertical strips? It would seem to prevent ANY potential for water wicking into plywood furring, and allow for horizontal air flow also. Your thoughts appreciated. Should spacing of furring strips be 16″ or +/- to prevent cedar claps from cupping/sagging.

Yes that would be the ideal senerio, only if money is of no concern. You could also use a 3/4 stock furring strip primed, it would be less money and do a great job. Good Luck. Ron
*In response to father buffalo's question, plastic furring strips would be ideal, especially if they were comprised of post-consumer waste. High and low I searched and couldn't find a darn thing that was affordable and available. That is why I chose wood. Regarding corevent as a vertical spacer, not a good idea. The vent channels go perpendicular to the product which worked on a horizontal water board when additionally supported 16o.c. by the furring strips.The corevent applied vertically would compress and deform thereby creating a substandard product. I would not recommend using corevent as a furring strip. Good luck. Mark Averill Snyder aka Dusty board
*I'm not sure what the best material is for this application, but the idea is excellent. If ridge vent plastic strips could be found to provide adequate compressive strength. I think it would be especially useful to aiding with drainage and drying of sheet type claddings such as Hardipanel.The advantage of this material would be ease of application (presumably one could simply staple it in place vertically along the stud lines) and the fact that it wouldn't substantially change all the typical detail conditions, as it would only move the cladding outward 1/8" or so from the building paper/drainage plane. With 1x wood furring, many of the typical detail conditions require much extra material and labor to execute properly.
