Magna board is a "low tech" and "energy friendly" product. Magna board production is simple, energy efficient, and produces extremely few "greenhouse" gases... The manufacturing process of Magna board is eco friendly. Unlike, for example, the gypsum based drywalls that produce thousands of tons of green house gases annually in the manufacturing and drying process; Magna board is naturally dried and cured with no chemicals or heating, eliminating the power intensive drying process. Magnesium Oxide, the main ingredient in the boards covers over 8% of the earth's surface so the product is very sustainable too.
