Should I Insulate My Home?

Have an older home and haven't added insulation: in a recent survey, only 20% of homes built before 1980 were well insulated;

Are uncomfortably cold in the winter or hot in the summer—adding insulation creates a more uniform temperature and increases comfort;

Build a new house or addition, or install new siding or roofing;

Pay excessive energy bills;

Are bothered by noise from the outdoors—insulation helps to muffle sound;
