This customer in Winter Garden, FL, asked us to get rid of their old sliding glass doors and wanted a new 15 light French door unit. We did this transformation in 5 hours and left them completely thrilled with their new French door unit featuring the ODL Triple-Glazed Doorglass. The 3 layers of glass enclose both the blinds and grilles. This Triple-Glazed design greatly reduces heat and sound transmission. This unit comes with the 20 year ODL glass seal warranty. It is also 2015 Energy Star compliant.
