  • the insulating sheathing was secured to the wood buck using 16 gauge, 13 ⁇ 4′′ Senco staples with 7/16′′ crown and a pneumatic fastening system.
  • the staples were fastened at 3′′ on center at all edges and 6′′ on center in the field. Staples were installed at a depth where they were considered to be firmly resting on the paperboard layer of the sheathing upon insertion.
