The Truths about StrawbaleThe Truths about Strawbale• Strawbale is an economically viable, safe, and appropriate 

building material in many regions of the country

• Strawbale construction builds local economies by creating skilled labor jobs in both the agricultural and construction sectors

• Strawbale with natural plasters contributes to superior indoor air quality, which has a proven beneficial impact on human health and productivityand productivity

• Strawbale’s superior insulation values dramatically reduce energy consumption, protecting  businesses and homeowners from rising p p g genergy prices and reducing our dependence on foreign oil

• Strawbale’s low embodied energy, sequestered carbon content, and insulation value make it a potentially significant tool for lowering our country’s greenhouse gas emissions
