Insulate that attic!

Energy-saving advice from DREMC’s Pat Garrett, residential energy advisor

No matter what kind of insulation you currently have in the attic, one quick way to determine if it’s enough 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 rockwool being the most common.

By increasing the attic insulation value, you may be able to reduce costs associated with heating and cooling the home while increasing comfort.

Attic insulation should also be distributed evenly across the joists. The wind, which enters the home through drafts and openings near ceiling joists, can blow insulation away from eaves and leave some areas with little or no insulation.

Proper insulation of the attic is one of the best ways to control heating and cooling costs. For optimal results, it is recommended that R-38 to R-60 are used. R-values measure a material’s resistance to conductive heat flow. The higher the R-value rating, the greater the effectiveness of the insulation.
