Double-Hung Window with Simulated Transom

Peachtree. The 300 series double-hung window with simulated transom reduces installation time and hassle, compared with a standard double-hung unit with a mulled transom, according to the manufacturer. The simulated transom is created by extending the height of the top sash of a double-hung and adding a 3-1/2-inch profiled simulated divided-light grille bar.
