One of my dear friends commented on my last post
(Information on the 400 square feet house.)
and asked some good thought-provoking questions. With that said, I have been checking out the types of woods used and available for building log homes I suppose of any size but mainly for the tiny house. I also have been checking out durability and protection from pest such as wood boring bees and other invasive insects.
Here is some information I would like to pass along to you. First the type of wood used will probably depend on where you live. In other words if you live in the Southeast as we do the manufacture/builder will use the best would for your area. Not only is that good for keeping the pest away it is cheaper. Using locally sourced would bring the cost way down and the type of tree selected will have some natural defense against the bugs.
I have read that there are 80 or more commercial woods used in the United States and Canada to build log homes. These woods are used because they are readily available in their areas.
East and Northeast: white pine, red pine, Eastern white cedar.
Southeast: white pine, yellow pine, cypress.
Central: white pine, yellow pine, Eastern white cedar, hardwoods (oak, poplar, walnut).
West and Northwest: Western red cedar, spruce, fir, hemlock, ponderosa and lodgepole pine.
Next there is information that indicates that some trees are more decay and insect resistant, therefore manufacturers will capitalize on this to maybe indicate that the wood they are using is a bit better. Here is the facts: All trees produce a natural toxin in them that helps them fight off fungi and insects. Some trees are better at this than others it just depends on how much the tree produces. This naturally produced toxin is found in the heartwood. Species that produce a greater amount of heartwood and less sapwood seem to be more resistant to decay and insect infestation. When you smell the aroma of wood, you are actually inhaling its naturally produced toxins that make it resistant to fungi and insects.
The building company we have decided to use, Green River Cabins, exclusively uses white pine logs in constructing the exterior portions and main interior beams in our log cabins. The logs we use are acquired exclusively from Ellis Lumber Company and Logs in Shelby, North Carolina, which acquires and mills its logs for us to the optimal 4’’x12” commercial size. The logs go through a drying process. Green logs should never be used in making log cabins or any other commercial product. Logs need to be placed snuggly and sealed so that boring insects can not get in and infest the home.
The Green River Log Cabin company has excellent information on the processing of the logs and the treatment of them in the building process. One thing is to not paint your logs. Paint may be used to cover up mold, mildew, and fungus. There are different stains that can be used to help maintain the life of the logs in your cabin.
Finally logs need to be clean,dry, mold and mildew free, and sap free. It is suggested that two coats of stain be applied. Remember to consult with your build for what is right for you and the type of wood that is being used in your cabin.
