Double-Hung Windows Defined

Double-hung, also known as double-sash, are rectangular windows similar to single-hung designs. The difference with double-hung windows is they consist of two operable sashes, an upper and lower, instead of only one operable lower sash. The ability for both sashes to open provides superior ventilation and an added level of safety for homeowners with small children.
