Is it ok to let the bark siding sit in the weather prior to being installed?
The bark shingles should remain in an appropriate selected environment after coming out of the kiln and before being used. Bark that sits in the weather for extended periods prior to being installed can pick up moisture from the surrounding environment. Bark will swell or expand, and, when drier conditions exist, the bark can shrink on your home, exposing cracks. So over time some of the benefits that were gained from the kiln drying would be lost.
