I applaud the makers of bark siding. It is a way to use the entire tree and results in a siding that is naturally more resistant to insects, fire, rot, etc. Plus, it never needs painting, looks great, and lasts a very long time. We are putting bark siding on a mountain home we are building and it is gorgeous.
