Polyurethane Cornice

What is Polyurethane?

High Density Polyurethane is made of polyurethane foam created by mixing isocyanate and resin. The mixture is kept under pressure in a mold as it expands to the desired shape. The result is a high-density, thermoset material that is perfect for interior or exterior molding applications. Polyurethane is a wood alternative product with a closed cell structure that makes it impervious to rotting, insects, cracking, and any other negative attribute of wood. Our polyurethane moldings are shipped to your site primed twice with a durable primer ready for final paint finish. Please download our catalog for standard profiles or email us for our standard profiles as well as stock items. As with any of our products, we never shy away from custom profiles. In fact, most exterior cornice moldings are custom.

How is Polyurethane Made?

We are able to ship custom cornice pieces straight to your jobsite with low lead times. The very first step of the process is to get together with the client and find out what exactly is needed. Once we have determined the exact requirements and specifications, we get to work on the molds. Our in-house CNC capabilities allow us to make exact molds of massive size while still conserving the most minute of details. Once our molds have been programmed, cut, and inspected, we polish the surface to a mirror finish to keep any imperfections from transferring to the final piece. Once the molds are done, we mix together isocyanate and resin and pour them into the mold. Thanks to the expanding nature of Polyurethane, we are able to replicate even the most ornate designs while keeping the weight and costs minimal. Once the piece has finished curing, it is carefully removed from the mold and inspected to our standards. We then apply two coats of durable primer to prepare the product for the customer’s final paint finish. Once all of this is done, we then send the cornice to the jobsite where it is painted, framed, and installed by the contractor or homeowner.
