George -- you mean on milled log homes there is no chinking
-- and technically that foam strip is chinking
-- there are still a bunch of places around here that will sell you a "shell" cut from logs dowelled together in the traditional fashion. With foam insulation and modern chinking compounds the r rating ends up at least as good as the log thickness. Believe me I am not commenting on one over the other -- I think any log home is great and building or renovating any of them is a worth while accomplishment.
It's just that after several weeks of chinking, I was trowelling and smoothing the stuff in my sleep!
