Best Longevity Strategy for Rain Screen Furring
I’m installing 1″x 3″ furring strips to build a rain screen on my one-story new construction home. I’ll be putting yakisugi (aka shou sugi ban) wood siding vertically over a diagonal rain screen with Cor-a-Vent SV5 at top and bottom. All that is going on top of Zip sheathing. I’ll be needing to put up about 2,500 lineal feet of furring. The site for the home is Puget Sound coastal and gets heavy wind and driven rain in the winter months.
My question is whether it makes sense to try to increase the lifespan of the furring strips, given the theoretical extended longevity of the yakisugi siding?
Beyond just installing plain rough sawn 1″ x 3″ furring, I could also go with treated furring lumber, or pre-paint the furring with an exterior paint, or even seal the furring strips with Zip flashing tape after installation before the siding. Or maybe something else I haven’t thought of….
Any thoughts on whether I should protect the furring somehow and, if so, what’s the best option?
