Improve the Energy Efficiency of Your Siding

The ability of a product to restrict the flow of heat is measured in "R-value"*. The higher the r-value, the better the product's insulating ability.

As you can see from the chart below, siding products provide minimal R-value because they weren't designed to help you combat energy loss. Therefore, if you want to insulate your exterior, you must add insulation under replacement home siding. The United States Department of Energy says "When new siding is to be installed, it's a good idea to consider adding thermal insulation under new siding."²

Fullback^®FC siding insulation is designed to be installed under new fiber cement siding and adds R-3.4 continuous insulation to your wall system. This breaks the thermal bridge and helps to reduce your energy bills.

There is never a more cost-effective time to add insulation to your home's exterior than when you choose to replace your home siding. Choosing to add Fullback^®FC to your house siding replacement will save you energy dollars every day that it is on your home!

Visit http://www.ftc.gov/os/1999/08/rvaluefr.htm for full information regarding R-value. The wall system R-value range is an industry range based on the collective R-values of all insulated siding products offered by various manufacturers.
