Attic Insulation Thickness Calculator – Lowes
Attic insulation thickness plays a crucial role in maintaining a comfortable and energy-efficient home. Our calculator helps you determine the ideal thickness for your attic, ensuring optimal performance and savings.
How to Use This Calculator
- Select your climate zone from the dropdown menu.
- Enter your attic’s floor area in square feet.
- Click the ‘Calculate’ button to see your results.
Formula & Methodology
Our calculator uses the following formula to determine the recommended attic insulation thickness:
R-value = (Climate Zone * Attic Floor Area) / 1000
The R-value represents the insulation’s resistance to heat flow. Higher R-values indicate better insulation.
