Proper insulation of the attic is one of the best ways to control heating and cooling costs.
Regardless of the type of insulation currently in the attic, the key is having enough to meet energy efficiency guidelines. One quick way to determine if your attic insulation is adequate is to look across the span of the attic area. If the insulation is at or just below the ceiling joists, more insulation will increase energy efficiency. Using a ruler, measure the depth of the insulation. The depth should be no less than 13 inches for an R-38 value, depending on the material used: fiberglass, cellulose, spray foam or rock wool are the most common.
By increasing the attic insulation value, you may be able to reduce heating and cooling costs and increase comfort.
Remember that attic insulation should also be distributed evenly across the joists. Wind can enter the home through drafts and openings near ceiling joists and blow insulation away from eaves, leaving some areas with little or no insulation.
For optimal energy efficiency, it is recommended that R-38 to R-60 be achieved with attic insulation. R-values measure a material’s resistance to conductive heat flow. The higher the R-value rating, the greater the effectiveness of the insulation.
