Insulation keeps your home warm in the winter and cool in the summer. Insulation is measured by R-value, which refers to its ability to resist heat flow. The higher the number, the better the insulating power. Recommended R-values vary from area to area.
In the Chicago area, Zone 5, when replacing siding, R5-R6 insulative wall sheathing is used beneath the new siding. A properly insulated home can deliver comfort and lower energy bills during the hottest and coldest times of the year.
In addition to siding, look for other areas to improve energy efficiency, in particular, leaky or poorly installed windows.
