Insulation works by creating a thermal barrier that keeps warm air inside during winter and blocks excessive heat from entering during summer months. Homes throughout the region benefit from proper insulation, whether you live in an older neighborhood near downtown Raleigh, a newer subdivision off Capital Boulevard in Wake Forest, or a lakefront property along the shores of Lake Gaston. Rural homes scattered along Highway 158 toward Henderson and properties tucked away on country roads near Littleton and Valentine often have unique insulation challenges due to their construction styles and exposure to the elements.
