Understanding Insulation Requirements
Proper insulation is crucial for energy efficiency and comfort in buildings. The science behind insulation involves understanding thermal resistance (R-value) and how different materials and climate conditions affect insulation requirements.
R-Value Explained
R-value measures thermal resistance - the ability of insulation to resist heat flow. Higher R-values indicate better insulation properties:
- Basic Principle: R = thickness / thermal conductivity
- Metric: m²·K/W (meters squared Kelvin per Watt)
- Imperial: ft²·°F·h/BTU (square feet times degrees Fahrenheit times hours per British thermal unit)
- Additive Property: Total R-value is the sum of all layer R-values
