Hardie Boys Cellular PVC Soffit Systems typically have 4 components - fascia, soffit panel, frieze board and rafter tails. To begin, it's important to understand what these components are, and also their vital functions.
The fascia is a finishing edge board which is installed around the outside of a home and is attached to the ends of the roof trusses. The fascia board covers the outside perimeter like a decorative molding piece around the area where the soffit forms the ceiling. It provides a smooth continuous appearance to the edge of the roof.
