Timber Frame Wall U Value Calculator

Introduction & Importance

Timber frame walls are a popular choice for construction due to their strength, durability, and aesthetic appeal. However, understanding their thermal performance is crucial for energy-efficient design. The U-value, a measure of heat transfer through a building element, is a key factor in this regard.

U-value is defined by the U.S. Department of Energy as the “rate of heat transfer through a building assembly… measured in units of Btu per hour per square foot per degree Fahrenheit (Btu/hr-ft²-°F) or Watt per square meter per Kelvin (W/m²K).”
