Soffit Systems

What is a Soffit System?

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.

Soffit ceiling is the covering that forms a ceiling on the underside of the roof in the area that extends beyond the walls of a home. Simply put, it covers the gap between the wall and the fascia, also referred to as the eave. It can also cover the underside of arches, stairways and balconies.

The frieze or frieze board is a trim board that runs along the top of the house’s wall, forming a corner with the soffit.

Traditionally, in a timber framed roof the rafter tails or truss tails were the portion of rafter that extended beyond the exterior walls.  With the common prefabricated truss system rafter tails are generally components that are attached to the soffit for aesthetic purposes. They are sometimes left square but often have a decorative profile at the end.

The function of these combined parts is to seal the upper part of the building envelope below the roof, provide protection from the elements, create additional shade- reducing solar impact and not least of all they add detail and character to the overall architectural design.

The components of a soffit system were originally made from wood and later vinyl and aluminum. The problem with wood is that it is susceptible to pests, mold, rot and requires continual upkeep. Vinyl fades, is flammable, is more susceptible to movement, and is not very aesthetically pleasing. Aluminum can bend, dent and pit, and is not easy to repair or refinish once installed.

Now, with newer technology, Free Foam Cellular PVC, often called cellular PVC, has resolved these issues. This material resists termites and other insects, pests, mold, rot, heat damage and many other problems that have traditionally plagued the soffit system.  It has excellent paint adhesion and is easy to install.  It’s available in a variety of styles which add beauty and character to your home.

Hardie Boys, Inc. is the leader in high-quality cellular PVC soffit systems.
