Making a well-built window box (also called window buck) for your cordwood home is crucial.  Done properly your windows will open and close with ease in perpetuity.  There are a couple of important points to follow.

  1.  Buy your windows first so you can make the right size window box. Window boxes 1.jpg
  2.  Make the window box out of dimensional lumber for added strength adding 1/4″ to each side (called the rough opening).  Have windows of all the same size:  make a template like in the picture above. White Earth small pixel window boxes with keyways on inside and outside.jpg
  3.  Secure the window box to a post, top plate, lintel or framework.  Window box with top plate and masons line.jpg
  4.  Brace the window box diagonally so it stays square, level and plumb.Window install into window box.jpg
  5. Stack your windows safely out of the elements and then install carefully to keep them level on the outside of the window box.  If they come with a nailing flange, make sure it is nailed securely to the outside edge of the box. Cordwood window with logo.jpg
