Install Base Trim and Lower Vertical Panels

What happens here

This step begins the actual installation of the vertical siding. A horizontal composite plank is first installed at the base of the framed wall, likely serving as a starter strip or trim piece. Following this, the first few vertical composite planks are installed, starting from the bottom and working upwards. These planks appear to interlock or have a tongue-and-groove or shiplap profile, allowing them to stack neatly and uniformly. They are being placed over the existing wooden framing (studs) and house wrap (Tyvek). Fasteners are not clearly visible in the video but are implied to secure the planks to the studs, likely hidden for a cleaner finish.

Goal: Establish the base for the vertical siding and begin installation of the lower panels.
