How much insulation do i need for a 2100 sq ft home?

The amount of insulation needed for a 2,100 sq ft home depends on various factors, including climate zone, type of insulation, and the areas being insulated (attic, walls, basement, etc.). Generally, the recommended R-value for insulation varies by region, ranging from R-30 to R-60 for attics and R-13 to R-21 for walls. It's best to consult local building codes or an insulation professional to determine the appropriate R-value and amount for your specific home and location.
