Using traditional materials, joinery and profiles and modern technology, such as high-performance, energy-efficient glass with “warm-edge spacer bars,” we developed a line of reproduction true divided-light wood windows with insulated glass and historically accurate muntin bars as narrow as 7/8-inch. True divided-light sash reflects light differently than simulated divided-light sash and are generally required by historic district commissions.
Our true divided-light windows have been approved by every landmark commission that has reviewed them.
They are available as double-hung, casements, awnings, hoppers, fanlights, etc. As with all our products, numerous options in profiles, glazing, hardware, and weather-stripping are available.
Our windows have been tested in accordance with AAMA/WDMA 101/IS2 and have been computer simulated for thermal performance. Energy performance, however, varies with the type of glass specified. Glazing options include insulated glass made from reproduction hand-blown cylinder glass, beveled glass, bent glass, tempered, laminated, Low-E, or argon-filled glass.
With our proven weather-stripping and glazing systems, our windows meet or exceed the performance standards for structural integrity, air and water infiltration, resistance to forced entry, and ease of operation.
