• LOGS are natural insulators

• Forget R-value, think thermal mass
  

• Unlike man made insulation, logs insulate by thermal mass which simply means
  they "store" heat and release it later
  

The national institute of Standards reports log homes use less energy.

• Spring..................................46%
  
• Summer...............................24%
