Our windows are constructed with traditional mortise and tenon joinery for a traditional look and a long-lasting joint. All of muntins (glass dividing bars) are True-Divided. We use insulated glass for better energy efficiency than traditional single pane glass and modern weather-seals to create an air-tight seal. We replace fixed sashes, casement windows, transoms, storefronts, awning windows, and more. Of course, all of our products can be customized to incorporate traditional single-pane glass, restoration (wavy) glass, metal weather-seals, historically accurate brass hardware, and custom sticking profiles/sash horns.
