Choose the Best Insulation for Efficiency

When it comes to attic insulation, you’ve probably heard about R-value and what it does. If not, here’s a brief explanation: “An insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value — the higher the R-value, the greater the insulating effectiveness. Installing more insulation in your home increases the R-value and the resistance to heat flow.” That’s great information but how do you know the right amount to use in your home? You need to remember that R-value is additive. If you have exterior siding or 2×6’s in your home, your R-value will be higher than a home without…
