True Divided Light Windows vs. Simulated Windows


It’s easy to confuse true divided light windows with simulated divided lights (SDLs)—but the difference is critical in historic preservation.

True Divided Light (TDL) Windows:


  • Each pane is individual glass
  • Real wood muntins separate each pane
  • Offers maximum historic authenticity
  • Required for many local and national historic designations

Simulated Divided Light (SDL) Windows:


  • One large pane of glass with surface grids
  • Often includes a spacer bar between glass layers to mimic depth
  • Common in modern builds or mass-produced replacements
  • Easier to produce, but lacks the craftsmanship of TDL

At Historic Window Co., we believe true craftsmanship deserves real materials. If your home is under historic review, true divided lights are often required to maintain architectural status. We work directly with local preservation offices in Kansas City, Overland Park, and Olathe to ensure compliance with historic standards.
