1898 Window Series
All-Wood Single-Hung
Rivertown Window’s 1898 Window Series is the culmination of decades of experience building windows for structures built at the turn of the last century. The window features a 1-11/16" sash thickness, which was commonly used in windows of this era. This single-hung window features a 7/8" insulated glass unit (IGU), which allows for better insulating properties and more Argon gas (when specified) than our previous window design. For the balance system, we partnered with America’s oldest spring manufacturer to integrate a concealed-balance system that preserves the historically accurate sight lines of the window.
