The higher the R-value, the a lot more reliable an insulating product is. Your house's R-value rating will direct you toward the kind of insulation you require.

- Energy costs vary greatly over each zone
- Installed insulation costs vary greatly over each zone
- Heating and cooling equipment efficiency varies from house to house
