Double Sash / Box Windows

Historically accurate double box windows.

Often compliance with the historical building reconstruction or renovation requires the use of double sash box windows.

Utilizing our extensive experience with historical construction, we have perfected the manufacture of this type of window.  We can now produce these windows inexpensively with Building Department Certificates of Compliance, using our automated modern production lines and facilities.  We have incorporated historically accurate elements, including historically accurate sash, mullions, transoms, beveled sash bars, exterior sash drip profiles, and true-divided lites.

Frequently in response to the need for a window that meets modern energy conservation requirements, we have provided inner sashes with multilayer insulating glazing to protect against temperature differences and exterior ambient noise.

Operational and aesthetic hardware concerns are also of utmost importance to us.  We can provide period hardware with modern functionality.
