Proper attic insulation helps regulate the temperature in your home; it traps your AC's cool air in the warmer months, and stops warm air from escaping through your attic in the winter. You can look forward to a more comfortable home, and lower energy bills every month.
Attic insulation allows your home to maintain its appearance. When temperatures are kept stable, your roofing will last longer, paints won't bubble, and your interior rooms won't have extra moisture.
The R-value rating refers to the insulations thermal resistance - its ability to resist heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness, and density. Installing more insulation in your home increases the total R-value and the resistance to heat flow.
