A no-VOC earth plaster for a breathable, bioclimatic home

Modern homes are often built so air-tight to provide good insulation that they don't allow for fresh air to enter. Earth plasters, also called mud plaster and clay plaster, can play a role in creating a breathable home, i.e. walls that allow fresh air to slowly enter. Also called mud plaster and clay plaster, earth plasters are simply a mix of sand and clay and optional chopped straw. They're powerful in their simplicity as they allow the walls to breathe, allowing toxic vapors to escape without any heat loss. On *faircompanies: http://faircompanies.com/videos/view/...
