k8RQsvj3yc | Posted in Building Code Questions on

Referencing GBA diagram “Plan detail // cement board lap siding // 1 1/2″ rigid insulation” as a starting point, If I am attaching the furring thru the foam to the studs, what is the fastening requirements, specifically screw size, spacing and stud penetration depth? Thanks
