Your measurements
Use one product, thickness and pack size at a time. Enter the product's stated coverage for that thickness. For loose fill, use its coverage at the specified installed depth and enter one layer.
Example only. Replace these numbers with your job measurements and plan.

How this insulation calculator works
Area to cover = (area minus openings) × entered layers. Multiply that area by (100 + waste percentage) ÷ 100, divide by coverage per pack, and round up once to whole packs. Coverage must match the product, thickness and installed depth in your plan.
Check a worked example
Arithmetic only: (500 − 50) × 2 = 900 sq ft across two layers. With 5% extra, that is 945 sq ft. An invented coverage of 40 sq ft per pack gives 23.625, rounded up to 24 packs. No example coverage, layer count or thickness is a recommendation.
Before you order
This is a quantity estimate. It chooses no insulation type, R-value, depth, vapor control, fire rating or wall assembly. Do not combine packs with different coverage in one calculation. Confirm the material and assembly with your engineer or architect. The yard confirms the requested pack and availability.
