In the mid-70’s Cliff Shockey of Vanscoy, Saskatchewan, Canada decided to build an energy efficient home of recycled cordwood, but since he lived where the temps would go down to -50, he decided to build “double wall.”
This double wall cordwood home is on Vancouver Island in British Columbia, Canada.
He built a post and beam framework and laid up 8″ of cordwood on the outside. Then he put 12″ of stiff fiberglass insulation (there are many insulation choices) and then another 8″ of interior cordwood. He had 20″ of wall with an R-value approaching R-50. Cliff won the Harrowsmith award for Energy Efficiency in 1997. His design continues to inspire folks to this very day.

A number of folks thought this was a good idea and decided to build double wall and try and improve on Cliff’s design.

Bruce & Nancy Kilgore’s beautiful double wall cordwood home in upstate New York.
Bruce & Nancy Kilgore built a trapazoidal structure in upstate New York with double wall. Where Cliff went all the way with his mortar, Bruce and Nancy used 3″ of mortar, 2″ of sawdust insulation and 3″ of mortar on each side of their double wall creation.
Greg and Clare are building a wonderfully unique double wall home near Houghton, Michigan. They are using Lime Putty Mortar and blown in foam for a higher R-value.

Alan Stankevitz’s double wall beauty near LaCrescent, Minnesota is an excellent example of double wall with renewable energy. Alan is almost at a break even point when it comes to energy used and energy produced. You can learn more about Alan at www.daycreek.com by going to the Journal.

All of these stories are written about in the Cordwood Conference Papers 2005 and/or 2011. The attention to detail and the sweat equity of each project is significant and profound and needs to be seen to be believed.
