Apply Water-Resistive Barrier (House Wrap)

What happens here

The final visible step in the video is the application of a water-resistive barrier, commonly known as house wrap (e.g., Tyvek or similar brands). A worker is shown rolling out large sheets of black house wrap over the newly installed plywood sheathing. This material is cut to size using a utility knife and then fastened to the sheathing, typically with cap nails or staples. This layer provides crucial protection against moisture intrusion, acts as a secondary drainage plane, and reduces air infiltration, thereby enhancing the durability and weather resistance of the pavilion before the final siding is installed.

Goal: Install weather protection layer over exterior sheathing
