The amazing air quality available in Enviro-Ment Buildings is thanks, in part, to lime's ability to transfer, not trap, water vapor. In conventional construction vapor is absorbed into the walls where it condenses and can cause mold, mildew, and other biological growth. In Enviro-Ment Buildings, the stucco, mortar, block ,interior plaster, and insulating grout are all made with the same material. The microporosity of the components (shown above in blue) allows for vapor transfer and healthier walls. Click here for more.
