Estimate batt packs or rolls from wall, attic, or floor area—subtract openings, add waste, and round up to whole packages.
Area to insulate
Total length of walls to insulate (sum of wall runs).
Doors, windows, hatches, and other areas you will not insulate.
Product & coverage
Presets are typical package coverages—always use the sq ft (or m²) printed on your product label for the chosen R-value.
Use 2+ when stacking layers for higher R-value.
5–10% for simple rooms; 10–15% for odd cavities.
Insulation needed
Cost estimate
Enter a pack price to estimate material cost (excludes labor and vapor barrier).
