How to Measure Attic Insulation

PLEASANTON — Attic insulation is a key component of an energy-efficient home. By keeping hot and cold outside air from entering the home, a well-insulated attic can go a long way toward minimizing your heating and air conditioning bills. However, simply having attic insulation isn’t enough—you also need an adequate amount of it. Otherwise, you won’t achieve the optimum level of energy-efficient performance.

Fortunately, it’s easy to determine whether you have enough attic insulation—all you really need is a tape measure. Simply stick your tape measure down into your insulation and measure its thickness. The minimum recommended level of attic insulation is R38, which is between 13 and 14 inches thick. So, if your attic insulation is at least 13 inches thick, you’re all right. If it’s less than that, you might want to consider adding some more to maximize your home’s energy efficiency.
