Energy Efficiency
Studies have shown log homes to be as, if not more energy efficient than conventionally framed houses. Log homes derive their energy efficiency through Thermal Mass, the process of absorbing heat and storing it. When the temperature in the home drops below that of the log wall, the stored heat energy is radiated back into the home. With log siding you are adding logs onto walls that already have insulation installed, only adding to the energy efficiency.

Shrinkage
Shrinkage is all about moisture content. When logs settle or dry out shrinkage occurs. Builders must make allowances and prepare for shrinkage of  approximately 1/8 (one eighth) of an inch per 8 inches of log height, especially when logs are 'green' or 'wet'.  Drying and shrinking is actually the process whereby the water/moisture evaporates out of the woods cells.  Once the cells no longer contain water or 'dry' they become smaller.

Maintenance
You’ve spent time, money, energy and put your heart and soul into your home, now it’s time to protect it.  Just like conventional homes, log homes need to be maintained in order for them to keep their brilliance and strength. It’s important to visually inspect your home annually to catch any problems quickly.

One point in particular to keep an eye on is damage from insects, mould or sun/UV damage.  The southern wall will bear the brunt of the sun's harmful rays. The finish can flake off and slowly erode from theface of the log. Once this happens rain can get in promoting mould and rot.

To prevent all these problems a clear Ultra Violet protectant should be applied as needed, though most houses will only require a maintenance coat once every 4 to 5 years.
