What happens here

The exterior walls are framed next, consisting of a single bottom plate and a double top plate. These plates sandwich the vertical studs, forming the wall structure. It is common practice to install OSB or plywood sheathing (7/16 inch or thicker) on the exterior of the framed walls. This sheathing extends below the mud sill, covering the rim joist to provide continuous protection and structural rigidity. When these walls are stood up, the sheathing must extend below the mud sill to protect the mud sill from moisture and contribute to the building envelope.

Goal: Frame and sheath the exterior walls to create the building's perimeter.

These plates overlap and accept the other wall. This locks your
