The Defining Window of Historic Architecture
Historic Double-Hung Windows
The double-hung window is the most common window type in historic American architecture. We replicate historic double-hung windows with the accuracy and craftsmanship that preservation requires.
Replicating America's Most Historic Window Type
The double-hung window — with two independently operable sash that slide vertically within the frame — has been the dominant window type in American residential and commercial architecture since the colonial period. Its proportions, sash configurations, and profile details are defining elements of virtually every historic architectural style, from Federal and Greek Revival to Victorian, Craftsman, and Colonial Revival.
Replicating a historic double-hung window accurately requires more than matching the overall size. The proportions of the upper and lower sash, the width of the rails and stiles, the profile of the meeting rail, the muntin configuration, and the glass pane sizes all contribute to the window's architectural character — and all must be matched to produce a replica that reads as original to the building.
Components of a Historic Double-Hung Window
Upper and Lower Sash
Each sash is an independent frame containing the glass panes. We replicate both sash to match the original's dimensions, rail and stile profiles, and lite configuration — whether replacing both or only the deteriorated unit.
Meeting Rail
The meeting rail is the horizontal member where the upper and lower sash meet at the center of the window. Its profile, width, and fit are critical to both the window's appearance and its weather performance.
Rails and Stiles
The top rail, bottom rail, and side stiles form the perimeter of each sash. Their widths and profiles vary by period and building type — we match these dimensions precisely from the original window.
Muntins and Divided Lites
Muntins are the wood bars that divide the sash into individual glass panes. We replicate the original muntin profile and lite configuration using true divided lites — individual panes of glass in solid wood bars, not simulated grilles.
Built from Sapele for Florida's Climate
Our historic double-hung window replicas are built from premium Sapele hardwood — chosen for its dimensional stability, natural durability, and suitability for exterior wood windows in Florida's humid subtropical climate. Sapele resists the seasonal movement that causes wood sash to bind and stick, and its surface accepts paint and finish exceptionally well.
