In its launch of Terralite Cement, designed with a proprietary blend of cement binders, special additives and a tiny, lightweight aggregate, Terra Bona emphasizes the material’s potential to deliver increased R-values and performance over conventional lightweight concrete.

Terralite Cement yields a product that is easy to mix and place; exhibits sound and thermal insulation properties; and is freeze-thaw and fire resistant. Suited to interior and exterior conditions, Terralite-based concrete is 20 percent the weight of traditional concrete, making it ideal for roofs, floors, walls and geotechnical fill, while offering increased strength over cellular concrete and predictable mechanical behavior.

“The need for energy efficiency is driving an increased focus in the building science community to find sustainable products and material to address this issue,” says Terra Bona President Terry Cotton. “Terralite delivers very high thermal value and has been successfully used in Europe for over a decade, resulting in energy cost savings of up to 40 percent when compared with standard building structures and materials.”  —
