Cooler in the summer and warmer in the winter? Proper attic insulation (and air circulation) is the key to a healthy roof and year round reduced energy bill as well as a more comfortable place to live and work. In fact, properly installed attic insulation is arguably the #1 way to increase the energy efficiency of your entire home or business and maximize the lifespan of your roof system - no matter what material it's comprised of. Do you have rooms that feel drafty or cold floors? Too hot or too cold? Utility bills that are getting higher? Do you experience fluctuating temperatures as you walk from room to room in your home? When you're upstairs, is it significantly warmer than the downstairs? All of these things and more could be signs that you don't have the proper amount of insulation or your attic insulation has been damaged by moisture.

Fiberglass Insulation is by far the most common material used. It is inorganic, non-toxic, non-combustible, odor free and cannot absorb moisture. It is available in two types– blanket (batt) and loose-fill (blown-in).
Adding Attic Insulation
When adding additional insulation, you do not have to use the same type of insulation that currently exists in your attic. You can add loose fill on top of fiberglass batts or blankets, and vice-versa.
How Much Should I Add?
Insulation levels are specified by R-Value. R-Value is a measure of insulation's ability to resist heat flow. The higher the R-Value, the better the thermal performance. The recommended level for most attics is R-30 minimum, or about 12 inches.
Comfort – Savings
Adding needed insulation keeps interiors cooler in summer and warmer in winter. Comfort levels are improved. Energy is saved. Noise is reduced. Insulation pays for itself year after year.
