Low Embodied Energy

Low embodied energy

Clay plasters are regarded as having the lowest embodied energy of any interior finish. A recent study has shown that they have 50% less embodied energy than standard cement plasters(3).
 
Armourcoat Clime clay lime plasters incorporate naturally abundant materials such as clay and limestone which have lower energy requirements in production thereby reducing additional materials and processes required for creation. The processing of local clay soils into plaster requires only small-scale excavation, with no heat or complex mechanical processes involved.  Being locally sourced material, transport distances are often minimal compared to other materials.  Trees and natural ecosystems are undisturbed.
 
These traditional finishes were largely replaced in the last century with synthetic, non-breathable building materials.  A modern revival is underway with a move towards natural homes and work places, with many environmental and health benefits.
