BRICK
Clay bricks can last hundreds or even thousands of years.
building. Tests conducted by the Oak Ridge National Laboratories of this benefit have shown energy savings as high as 13 percent.
Durability
CLAY BRICKS can last hundreds or even thousands of years. Other than stone, no other construction product lasts as long as bricks. This construction durability adds value to any property when considering life-cycle costs. Masonry durability reduces both the monetary and environmental costs of maintenance as fewer new resources are needed to repair the structure over time. In addition, the durability of homes and buildings built with bricks add a generational sense of community to towns, cities, village and neighborhoods all over the world.
Flexibility, ease of use
BRICKS CAN BE USED to achieve sustainability goals in every type of building, from single-family homes, hi-rise condominiums and office buildings to public institutions. Within a location, it can be used as an interior wall, floor, ceiling, fireplace profile and as a passive solar energy collector.
Additionally, bricks are used across the world in every economic region. The abundance of clay the natural, predominant material in bricks contributes to its universal manufacturing and application.
Humans have always used, and still use, clay bricks' thermal mass capabilities as an asset to construct long-lasting livable, attractive structures and can be used to effectively achieve today's sustainability goals, creating a stronger environment for tomorrow.
Revolutionizing the Environmental Impact of Masonry
CalStar Products is addressing the need for a high-performing brick that achieves a traditional look and feel, while offering significantly improved environmental credentials, by changing brick manufacturing.
Reducing the carbon footprint
The traditional brick-making process, during which clay is mined, dried and fired in a kiln powered by fossil fuels, releases about 0.9 pounds of carbon dioxide into the atmosphere, meaning nearly a full pound of greenhouse gas is generated for each brick. CalStar's propriety technology does not require firing and produces only 0.1 pound of carbon dioxide per unit, representing an 85-percent reduction from traditional bricks.
CalStar achieves this by using fly ash as the binder in the bricks. Each CalStar brick contains about 40 percent fly ash, a byproduct of electricity generation that would otherwise go into a landfill. This recycled content allows CalStar bricks to contribute to projects seeking LEED certification. CalStar's bricks also contribute to regional materials credits, for projects within 500 miles of CalStar's plant in Wisconsin.
Performance and sustainability
CalStar bricks meet or exceed ASTM standard performance requirements, and provide reliable performance and usability. CalStar bricks are easy to cut and lay. The bricks are freeze-thaw resistant, demonstrate exceptional dimensional consistency, and have the one-hour fire rating required of bricks of that size. They are available in modular and utility sizes.
Making a difference
CalStar bricks can be used in any design in which bricks are specified. They contribute to the sustainability goals of individual projects, while reducing the environmental impact of the building industry as a whole. Take, for example, the average elementary school with 30,000 square feet of modular brick. Replacing conventional brick with CalStar brick saves over 1 billion BTUs of energy; avoids nearly 81 tons of CO2 emissions; and recycles nearly 160 tons of material otherwise headed for a landfill.
For projects that seek to achieve the traditional look of masonry, while simultaneously reducing the environmental footprint, bricks from CalStar Products provide a solution that is comparable to clay in performance and price. To learn more, visit www.calstarproducts.com.
