Here are the best cordwood photo galleries I could find. They include good basic info and links to other cordwood resources. Enjoy.
“Also known as Stackwall, Stovewood, Firewood or Cordwood Masonry. Short lengths of debarked trees (cordwood) are laid with a mixture of mortar and insulating materials – such as sawdust or spray foam – in between the mortar. The longer the length of the logs, the better the insulation qualities. 12 inches to 18 inches is most common and wood species will also determine insulating value. On average, a 12 inch wide wall will have a 20-25 R value.”

Cordwood Building: The State of the Art by Rob Roy
“Cordwood masonry is an ancient building technique whereby walls are constructed from “log ends” laid transversely in the wall. It is easy, economical, aesthetically striking, energy-efficient, and environmentally sound.
Cordwood Building collects the wisdom of more than 25 of the world’s best practitioners, detailing the long history of the method, and demonstrating how to build a cordwood home using the latest and most up-to-date techniques, with a special focus on building code issues.
Author/editor Rob Roy has been building, researching, and teaching about cordwood masonry for 25 years and, with his wife, started Earthwood Building School in 1981. He has written 10 books on alternative building, presented four videos—including two about cordwood masonry—and has taught cordwood masonry all over the world.
