CalStar chiseled cast stone unit

Words: Dan KamysCalStar is expanding its line of cast stone products with a 24-inch-long (nominal) unit with a chiseled appearance that emulates natural, cut limestone.

The chiseled-texture units have a bed depth of four inches (nominal) and are available in four heights: four, eight, 12 and 16 inches (nominal). CalStar’s cast stone starts with molds mastered from real stone, contributing to an authentic look. By using several different faces per size and an alphanumeric installation guide inscribed on each piece, CalStar ensures installers can place the units in patterns that are not repetitive to the eye. The CalStar staff will assist designers with developing an installation hierarchy. In addition, units are available with a chiseled end for use in corners.

Unlike some products, the units are suitable for at-grade applications and, therefore, eliminate the need for starter courses. Other uses include band courses, wainscoting and window accents.

The cast stone products are made with CalStar’s process that incorporates up to 18 percent recycled content and eliminates the need for Portland cement, used to bind concrete masonry products; for calcium silicate materials, which require energy-intensive autoclaving; or for kiln-firing, typical of traditional clay brick. As a result, each product requires less energy to make as well as having a lower carbon footprint. The chiseled-face units are available in any of CalStar’s monotone colors.
