The White House windows are restored with Bendheim’s Light Restoration Glass®, the finest mouth-blown glass found in our country’s most prestigious restorations, including – in addition to The White House – Mount Vernon, Beauvoir, and Monticello. Light Restoration Glass® is gently distorting and identical to glass found in structures built in the 19th and early 20th centuries. Its subtle imperfections allow historically-accurate detailing of buildings and furniture.
