Bonfiglioli strapping size
Does anyone know why Bonfiglioli uses 1×3 straping instead of instead of 1×2?
In addition to additional cost, it requires 2 different assemblies: 1 centered for wall studs and 1 offset for plates and corners. The only functional benefit seems to be having additional nailing surface, which might be necessary given need to accommodate 4 mechanical fasteners: insulation to strap, then assembled furring to studs, then drywall to furring, and then trim/cabinetry/pictures on drywall.
Any concern with ripping down Zip-R to strips versus site-assembled?
The only differences I can come up with are assembly is fully adhered, OSB instead of lumber strap, strap has to be same width as insulation, and Polyiso not EPS
If Zip-R, with need for 1 less mechanical fastener, what size to rip strips?
