Landmark buildings with historic windows are meant to last for centuries, so why put in a product that might only last 10 years?

We are known for producing innovative, historically accurate windows for landmark buildings. Our reputation for historic windows is unsurpassed.

Here is how we provide you with some of the most innovative, highest performing, historically accurate windows:

  • Historically accurate sightlines
  • In almost every case, we can precisely replicate the original sightlines, down to the look of vintage, steel putty-glazed windows. It's not truly historic window replication unless it retains the same sightlines.


  • True divided lites
  • Historically accurate windows have true divided lites. They didn't use applied grid, ever. Applied grid is a modern attempt to simulate a historic window. To be historically accurate, you need individual panes of glass separated by true divided lite muntins.


  • The building process
  • Every window uses our proprietary building process, so you know that the window is quoted accurately, engineered intelligently, built precisely and delivered on time and on budget.


    Every historic building has its own story and its own special requirements. We have experience in these areas and can help make the process smooth and efficient.

    We can replicate nearly any historic sightline in a true divided lite window. This makes it easier to:


  • Get tax credits for your building.
  • Obtaining tax credits usually means building a historic window with modern performance ability. We have done this on countless projects. We can anticipate most of the issues in advance, helping to avoid complications.


  • Gain approval from historic districts.
  • We will work with you to ensure that any presiding historic districts approve the window provided.


    Replication is about the entire opening, not just the window. The product must be easy to install and anchor correctly. Appropriate sills and trim must be provided to complete the window and blend it seamlessly with the opening and the building itself. If a window doesn’t do all these things, it’s simply not good enough.

    We're not just interested in putting in a passable window. We're interested in the long-term preservation of the building.
