Finials are an old form of detailing found in many architectural designs. Ornate headboards and railings often have finials, drapes and chandeliers can have finials, and garden finials are very popular in outdoor décor.
Many homes in the United States still use finials today. Antique and modern finials are constructed out of brass, wood, and wrought iron. Classic or traditionally styled homes use finials on the home’s exterior and interior. Finials produced by Solar Innovations® are constructed out of cast aluminum or copper, and are utilized on outdoor structures, including conservatories, greenhouses, pool enclosures, and sunrooms. An addition of a finial is an affordable way to add charm to any structure.
There are varying styles and heights of finials avilable through Solar Innovations®. In cast aluminum, there are seven fleurs-de-lis available along with six ball and spire combinations. The ball and spire combinations can be matched in different pairs to create a custom finial unique to your specific project. Another great aspect of the ball and spires is the ability to act as a lightning rod. This is done by threading the finial and then connecting to the ground wire.
Lightning protection is a subject often misunderstood in the construction industry. It requires a subjective decision based on an examination of the relative critical nature of the structure’s location and its contents. Architects and engineers take site specific lightning flash density into consideration to determine the required lightning protection.
A Solar Innovations® structure can be designed to include a professionally designed lightning protection system by a third party lightning protection engineer with required two paths to ground and main size lightning conductors.
Solar Innovations® recommends a full lightning protection system for all structures. To do this, customers should bond the metal structure to its own earth-ground or tie it directly to an existing building’s grounding system.
Solar Innovations® can also integrate lightning protection and electrical bonding into various decorative accessories, such as finials and ridge cresting.

Aluminum or copper can be used for grounding systems. Copper is normally considered the better choice for electrical grounding because it is a better conductor than aluminum. This allows for the use of a smaller cable; however, when installed in an aluminum structure, there are concerns with dissimilar metal properties. This can be avoided by using aluminum components within the Solar Innovations® system and then converting with the appropriate isolation component outside of the structure to copper and terminating it at a ground rod location.
Lightning protection can be utilized in an aluminum or wood system. Solar Innovations® does not provide the ground wire. Most finials, with at least a minimum thickness of 3/16″, can be used as a lightning rod.
