Royal Corinthian

Synthetic Stone Cornice

Synthetic Stone, Composite Fiberglass & PVC Cornice

In addition to our RoyaLite™ FRP fiberglass and RoyalThane polyurethane cornice, we offer cornice in our other materials: RoyalStone™ Synthetic Stone, RoyalCast™ Composite Fiberglass, and RoyalPVC Cellular PVC.

We don’t devote an entire section to the latter 3 for the following reasons.  For simple paintable crown molding or cornice, the clear winner as far as availability, ease of use, and affordability is polyurethane. For pre-finished or paintable large, complex cornice or entablature of incredible strength per pound, the clear winner is our RoyaLite™ fiberglass cornice.

However, on occasion, Architects like a certain product and would prefer to use it for reasons of product consistency, robustness associated with weight, or simply preference. For example, many architects have specified RoyalStone™ cornice, door and window surrounds, pediments, and other façade details in order to match our columns and/or balustrades.  We have the ability to match our RoyalStone™ products with our FRP products so we encourage Architects to consider both options.  The Architect is the one of vision and we are here to help realize that vision.  All of our products come with limited lifetime warranties so there is no wrong choice.

If you are interested in our RoyalStone™, RoyalCast™, or RoyalPVC cornice, you may read about the product composition in related product sections.  All of our products of a specific brand have the same material composition and properties.  For example, RoyalStone™ columns, balustrade systems, architectural components, and cornice are all made from the same material.
