Cellulose Insulation Calculator
Calculate the amount and cost of cellulose insulation for your attic or walls. Determine material needs, R-value, and coverage based on your project dimensions.
Step 1: Area & Insulation Type
Understanding R-Value
R-value measures thermal resistance. Higher R-values provide better insulation. Recommended attic R-values are typically R-38 to R-60 in colder climates.
Step 2: Costs & Calculation
About Cellulose Insulation
Cellulose insulation is made from recycled paper and provides excellent thermal performance, sound absorption, and fire resistance when treated properly.

Cost Breakdown Analysis
Calculation Formula
Bags Needed = (Area × R-Value) ÷ (Coverage per bag at R-1)
To calculate cellulose insulation needs: Multiply the area by desired R-value, then divide by the coverage per bag at R-1. Add installation costs if applicable.
