Fiber Cement Siding

Green Facts:

• Contains 50% recycled content in the form of fly ash.
• Fly ash is a by-product of electric generation at coal-fired facilities. It has been used as an ingredient in concrete for more than 60 years. U.S. concrete suppliers routinely use fly ash in their concrete mixtures.
• CertainTeed is committed to resource conservation:
  • Our manufacturing facilities recycle the water used in our plants, resulting in a savings of more than 2 billion gallons per year.
  • The majority of wood fiber pulp used in our fiber cement products is supplied from sustainably managed forests.
  • By using fly ash in our product, nearly 100,000 tons of this material are diverted from landfills each year. Recycling fly ash also lessens the demand for virgin materials that would require quarrying, and substitutes for materials that may be energy-intensive to create, such as Portland cement.
• The fly ash used in CertainTeed’s fiber cement products allows the creation of a stable chemical matrix, resulting in optimum product performance.
• The innovative use of fly ash in our formulation not only improves the strength and durability of our products, but also makes them more flexible and easy to install. At the same time, the product has retained its superior paint adherence properties.
• This formulation has ICC Building Code approval (reference report #ESR-1668).
• As a result of this innovation, we are able to offer a lighter weight board without sacrificing quality and integrity. Boards made with fly ash are lighter than our previous formulations, which translates into less energy used to produce and transport.
