On the log cabin I built - I liberally notched the logs with my chain saw and slid the tempered glass down the notches and into place. Between the notch on the bottom log and the one on the top log there was 4+ inches allowing for shrinkage as the logs dried. After four years of drying I applied a bead of regular old window glazer putty to the bottom outside edge of the window. At that time the glass could still be moved up/down about one inch in its notches. The cabin was built in the summer of 1976 and still stand proud to this day.
