The green coated zip board serves as a secondary water resistive barrier for protection against any water intrusion that might get behind the siding. The black zip tape seals all the joints to help create an airtight thermal envelope. Sheathing is run horizontally and blocked at all joints to create a more uniform wall surface. This is important to eliminate any waves in the siding which can lead to failure in high winds, not to mention a less than ideal appearance.
