Double-wall Cordwood on Manitoulin Island, Canada

Double Wall Cordwood on Manitoulin Island, Ontario, Canada.

They built each stackwall in two parts – an inside surface and an outside one, both using 7 inch long logs, with two layers of 1 1/2 inch extruded polystyrene foam between them and some air space. Wire ties every 18 inches extend from one side of the stackwall to the other, binding the two log assemblies together through the foam, creating a total wall thickness of 17 inches. This wall thickness makes for some deep and cozy window sills as well.

David Migwans is an Ojibwa artist who carves wood, stone and antler, works with clay and paints. He spent weeks at the Willson house adding carved details into wooden lintels, door and window trim using hand tools and his uniquely Native artistic vision.

Chuc and Linda sell vegetables and preserves from their organic garden. They also grow much of their own food, and this means they have good use for a large food prep area, a design feature that’s part of the floor plan in a big way.   The link to the entire article

    Hi
    Really a nice house.
    What I am wondering about is, if the slightly protrudung logs are a good idea instead of using the plaster flush with the surface.
    if there is a recess it might be more damaged or affected by water.

    Also I find the use of polysterene not really consistent with the idea of buliding s.th. ecofriendly.This puts me off a bit.
    Polysterene is not a all a material I would use in such a building as there ar lots of better alternatives ( if tihe u-value is not the only important reason)
    sawdust with limepowder,, woodfiberboard, cellulose-fibers,mixture of clay with woodshavings etc.

    • Hello,
      I agree completely with your analysis. In my books and sites and writings, I give as many alternatives to mortar as have been successfully tried. Clay, hemp hurds, wood fiber, lime putty, papercrete are all examples of alternative mortars. We do the same for insulation and often use sawdust. This is merely an example of how one couple approached their cordwood building. Everyone has to choose their own level of sustainability. This worked for them. Would I use something different, absolutely.
      Thank you for your comments.

        Hi Richard
        i was only astonished about the combination of a sustainable construction with natural materials and the co-use of a completely environmentally unfriendly product.
        Sure its not up to you what other people do.

        I myself try to advise people in applying natural materials instead of polysterene, pvc etc, even if those materials might have a better r-value or supposedly better technical specifications.
        (usually its not true anyway and if, it does have has other disadvantages)

        But this is also in Germany and Austria a point which is often discussed.

        Anyway its interesting to see what other possibilities there are in the building process.
