Insulate that attic!

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

No matter what kind of insulation you currently have in your attic, one quick way to determine if you need more is to look across the span of your attic area. If the insulation is at or just below the ceiling joists, you should add more insulation to increase energy efficiency.

Using a ruler, measure the depth of the insulation; it 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 your home while increasing the comfort of your home.

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

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