What's the best field joint detail for rainscreen clapboards?
I'm installing horizontal cedar clapboard rainscreen siding. I was intending to face screw each board just above the lower course into 1x3 pine furring strips, installing 3" wide splines of aluminum behind the butted field joints. Unfortunately, the stainless screws at these joints will penetrate through the aluminum spline reducing it's effectiveness, made worse over time by the galvanic action between the stainless and the aluminum. I'm looking for options. Would an un-splined scarf joint be a better detail?
Thanks for your help,
