Understanding these standards helps builders create log homes that maintain energy efficiency while meeting building code requirements.

Energy efficiency requirements vary significantly by region:

Region	Roof R-Value	Wall R-Value	Special Requirements
Mountain (e.g., Colorado)	R-38+	R-21	Higher insulation values for ceilings and floors
Coastal (e.g., Florida)	R-30	R-13	Enhanced wind resistance (150+ mph)
Wildfire-prone (e.g., California)	R-38	R-19	Fire-resistant treatments, materials

Fire Safety Regulations

Fire safety is critical for log structures due to their combustible nature:

• ICC 400 Section 303 establishes fire-resistance requirements for log walls
• Log walls used as fire separations must have minimum dimensions of 6 inches
