Then the Insulation Industry Buried It The United States government proved it in 1925. Structures built from compressed earth endure indefinitely and cost less than two-thirds of a standard frame house. That finding was filed away. Thirteen years later, Owens Corning patented fiberglass insulation and needed the market to forget it ever existed. What followed was not a single decision. It was three interlocking systems, a thermal metric designed in a corporate laboratory, a federal mortgage standard built around that metric, and a national energy code written in 1975 by a committee of insulation manufacturers with no earthen builder present. Each system reinforced the next. Each made it harder to build with a material that has been proven across 9,500 years and on every inhabited continent. This episode covers what those systems buried: the physics of thermal lag and why a 140-pound cubic foot of compressed earth outperforms fiberglass despite losing every R-value test; the 1938 Owens Corning patent and the metric they invented to sell it; the FHA mortgage standards that locked earthen construction out of the postwar housing boom; ASHRAE Standard 90, the 1975 energy code written without a single adobe builder in the room; the 2-year Arizona ban on adobe construction; and the Oak Ridge National Laboratory study showing a rammed earth wall rated R-13 performing at the equivalent of R-25, results the Department of Energy published and the building code ignored. It also covers the revival already underway: New Mexico's Earthen Building Materials Code, now referenced internationally; portfolio lenders financing earthen homes again; and the soil sitting on your property right now that may already be the building material you need. 📚 Sources: Easton, David.
