Fiber Cement over 2″ Rockwool Comfortboard 80
I’m finding a lot of older articles on this, but not recent ones since it’s become common.
Is wood battens the current state of the art for installing lap siding fiber cement over 2″ exterior mineral wool board? Are 1×4 battens recommended over 1×3, and are nailing patterns well established?
In some places we would be installing it above synthetic stone veneer, which we planned to install on Dorkin Delta Dry & Lath directly over the rockwool. Any tips for detailing that border?
