Here’s a siding option that is starting to make a comeback—tree bark. Proponents of this exterior cladding applaud the way it reduces the visual impact of the home on the surrounding environment and its low-maintenance longevity—bark siding can last as long as 75 years. When harvested properly (without chemicals), bark is also an environmentally friendly product. Typically sourced from poplar trees, this by-product of the furniture and plywood industry would otherwise be discarded or turned into mulch. Opting to use it as siding helps make full use of trees are already felled for other purposes. Kiln-dried bark is apparently best, as the heat sterilizes the product against fungus and insects. Again—no chemical pesticides or fungicides used. Now before you go running off to find a local supplier, I suggest doing a little extra research. I’m not certain in what regions this siding performs best. The last thing a homeowner wants is a failing first-line of defense.
