Modern man has developed ways to solve these problems. Find out what type of poison and what concentrations they are using. One of them is that you can put a stain and sealant on your logs immediately. The last benefit to kiln drying is something I touched on earlier and that is quality control. The poison has residual properties and can continue to kill molds, fungus and bugs for a long time to come. No matter, if they leave gaps above the windows and doors to allow for the log wall to shrink and settle or have slots where they nail doors and windows to a log walls, their logs are green enough to demand some sort of mechanical solution to compensate for the shrinkage. All logs will check and this can't be stopped, but, by kiln drying, you can discard logs that check too badly or you can turn them in such a manner that bad checks no not collect rain water and lead to trouble spots on the outside of your log home. You can see this easily if you ever go into a lumberyard. Insects likewise do their part. While still alive, a tree plays host to all sorts of organisms. As for the insects, they are a bit more complicated as some insects will love dry wood as well as moist wood. Green logs are very heavy. Armed with this information you should be better able to make informed decisions when talking to log home manufacturers and dealers. When you look at a log, there is no way of guessing how it is going to dry. The inner part of the bark is called the cambium layer, and it is where the tree's sap rose and fell moving nutrients and water between the roots and the leaves or needles of the tree. So all we need to do to stop them is dry the wood out and then keep the wood from getting wet. If the manufacturer protects the logs under a shed, it will keep the rain off and speed up the drying process, but the amount of water in a home build of green logs can be huge. On one extreme you have the log home manufactures that build with fully kiln-dried logs. The log home manufactures that bring the internal water content down to 13% - 16% will leave them in a kiln for up to 30 days and will slowly move the temperature up to as high as 180 degrees. This is important as the bark used to protect the inter parts of the tree like skin protects our bodies. All log home manufacturers remove the bark to destroy this important habitat for the bugs, molds and fungus.In our case, we want to break this natural cycle and preserve this tree trunk using it to build a log cabin or a log home. Let's see how this is used to kill off the bugs, mold, and fungus and get rid of the water. If we are going to be able to control these potential enemies, we need to understand how they get there, how they live and what they need to survive. As long as there is moisture in the log, this will be a viable environment for our molds and fungus and they will continue to consume the tree trunk. Checking is another big issue with logs. These log home manufacturers place the whole log into a large kiln.As soon as the tree is cut, it begins to decompose.Let's first look at those that build with green or wet logs.In conclusion,.
