Free calculator that gives you an instant insulation cost, material, and R-value estimate, before you call a contractor.
Enter your square footage and insulation type (attic, spray foam, or blown-in). It detects your climate zone from your ZIP and applies the right DOE R-value target automatically, something most calculators skip.
See a full breakdown: material cost, optional add-ons, and final R-value. No sales calls, no guessing.
