Fortunately for you, I’ve compiled a list of the best 15 sustainable building material companies in Tennessee. From rammed earth and cob to earthbags and straw bales, these companies have the necessary expertise to get your construction projects off the ground. Stay tuned!
Rammed earth is an eco-friendly material made from sand, gravel, silts, clay, and water. These aggregates are mixed into a homogeneous mixture and rammed into place in formworks to create walls.
The sustainability of rammed earth is based on the fact that the material has a high thermal mass and low carbon footprint.
A high thermal mass helps maintain comfortable indoor night temperatures using heat absorbed during the day without relying on a central heating system. This helps conserve energy, reducing the bills.
