Types of Exterior Cornices: Which One Is Right for Your Home?
When it comes to finishing the look of a home, few elements make as much of an impact as a well-designed exterior cornice. Cornices aren’t just decorative—they help define the architectural style of a building and provide practical protection by directing rainwater away from the structure. Whether you’re restoring a historic home or finalizing a new construction, choosing the right type of cornice can elevate the entire exterior appearance.
At Architectural Mall, we specialize in fiberglass cornices and offer more than 200 unique profiles, giving homeowners, contractors, and architects unmatched flexibility in design. Understanding the most common styles and materials can help you make the best decision for your project.
Common Styles of Exterior Cornices
One of the most frequently used styles is the box cornice, which encloses the roof rafters to create clean lines and a polished, finished look. It’s especially popular in more modern or classical designs where symmetry and sharp profiles matter. On the other hand, an open cornice leaves the rafters exposed, offering a more rustic or traditional appearance—perfect for Craftsman-style homes or buildings aiming for vintage character. Some homes may require unique profiles, which is why we offer custom cornices as well. These are often used in historic restorations where preserving architectural authenticity is essential.
Why Fiberglass Is the Best Material for Cornices
The material you choose is just as important as the style. While wood has traditionally been used for cornices, it’s not always practical due to its tendency to rot, crack, or require constant maintenance. That’s where fiberglass (FRP) comes in—it’s lightweight, highly durable, and can be molded to replicate virtually any look. Fiberglass is especially ideal for larger or more complex projects where longevity and low maintenance are important. It’s also paintable and performs well in all climates, making it a go-to material for architects and builders across the country.
Other materials like polyurethane and PVC are also used for cornices, particularly in smaller or more decorative applications. Polyurethane is a good lightweight option and resists moisture and insects, though it’s best suited for areas that don’t need the strength of fiberglass. PVC works well for basic trim or fascia boards, but it lacks the flexibility and detailing needed for larger, custom cornice work.
For most exterior applications, fiberglass remains the top choice thanks to its durability, crisp detailing, and ability to match existing architectural elements. It offers the best balance of form and function, especially when you’re looking for a long-term solution that looks great and lasts for decades with minimal upkeep.
