ICF U-Value Calculator
ICF U-Value Calculator: A Comprehensive Guide
Introduction & Importance
Insulated Concrete Forms (ICF) are a popular choice for energy-efficient construction. The U-value, a measure of heat transfer, is crucial in ICF design. This calculator and guide will help you understand and calculate ICF U-values.
How to Use This Calculator
- Enter the thickness of the ICF wall, insulation, and the R-values of the insulation and foam.
- Click ‘Calculate’.
- View the results and chart below.
Formula & Methodology
The U-value is calculated using the formula: U = 1 / (∑R). Here, R is the thermal resistance of each layer in the wall assembly.
