CorniceStone^TM is an exterior composite material that provides tremendous flexibility by introducing decorative elements to exteriors in new construction or renovation. CorniceStone^TM offers a wide range of advantages for architects and designers including the capability for it to be made into large parts that would otherwise require more costly support structures and increased installation costs (as compared to other materials such as precast or GFRC).

CorniceStone^TM is an FRP composite made with natural aggregates and pigments to resemble limestone. This lightweight Class A fire and smoke rated product is ideal for exterior cornices, column cladding, panels, trim details and spandrels in both new construction and renovation. CorniceStone^TM is available in two standard textures and a range of colors, and is installed with minimal lifting assistance and jobsite disruption.






The CorniceStone^TM surface consists of a UV stabilized Isophthalic neopentylglycol (NPG) polyester gelcoat and aggregates. The back-up laminate consists of layers of glass fiber and polyester resin. Through a unique and proprietary manufacturing process, it achieves a face finish that resembles a limestone texture. The CorniceStone^TM composite material has a Class 1 (or A) fire rating. When CorniceStone^TM is molded into shapes, the geometry of the shape imparts physical properties to the parts, such as strength and stiffness. For example, the design profiles of CorniceStone^TM parts that include recesses, projections, grooves, curves or ornamentation, make the part stronger. The nominal shell thickness of parts is 3/16". However, areas of parts that have flat regions are cast thicker by encapsulating core materials into the laminate that provide added strength and stiffness.







In most cases, CorniceStone^TM molded parts are secured to the building structural framing or light gauge steel substrate with concealed fasteners. Joints between are generally minimized and advantageously positioned in consideration of part size and design, overall appearance, and installation. CorniceStone^TM parts are typically supplied with pre-made corners to minimize field mitering.








Typical Cornicestone^TM applications include facade panels, columns, cornices, pediments, storefront entries, cupolas and other decorative elements such as friezes and signage
