‘D’: Single double-hung window without lowlights or sidelights.

‘DD’: Wide double-hung windows are fabricated in banks of two or three sets of opening sashes or ‘DF’ or ‘DFD’ windows where a fixed light has been included in the window.

The fixed sidelight, lowlights and highlights have been designed to match the double-hung window using the same perimeter frame and fitting a sill adaptor to position the glass in the fixed sidelights to match the adjoining opening sash.The windows illustrated right show a ‘DD’ window with fixed arch highlight.On wide transom windows in high wind load areas the transom strength will become the weak link

‘DFD’: Like ‘DD’ and ‘DF’ windows we can also offer ‘DFD’ and ‘FDF’ double-hung windows.

Couplers: A large variety of couplers allow this window to be snapped to all other Vantage windows and doors.
