How to Use the Insulation Calculator
Step 1: Enter Dimensions
Input the length, width, and height of the area you want to insulate. Our calculator works with both metric and imperial units.
Step 2: Select Insulation Type
Choose from fiberglass, cellulose, spray foam, or rigid foam insulation types, each with different R-values per inch.
Step 3: Set Target R-Value
Enter your desired R-value based on your climate zone and building requirements. Higher R-values provide better thermal resistance.
Step 4: Get Results
Instantly calculate the thickness needed, total square footage, and estimated material costs for your insulation project.
