The Victorian era saw a dramatic shift due to the repeal of the Window Tax in 1851 and the innovation of plate glass. Homeowners no longer required to optimize little panes; rather, they preferred bigger, heavier sheets of glass. This caused the "two-over-two" sash style. To support the weight of the much heavier glass, Victorian contractors introduced "sash horns"-- decorative lugs on the side of the sashes that supplied structural reinforcement.
3. The Edwardian Era (1901-- 1914)

For centuries, wood was the undisputed king of window building and construction. Nevertheless, the 20th and 21st centuries have actually introduced new materials that attempt to duplicate the look of wood with less upkeep.
Wood (The Heritage Choice)Hardwood: Oak and Mahogany offer incredible sturdiness but come at a premium price.Slow-grown Softwood: Often utilized in original windows, though contemporary fast-grown pine is less long lasting.Accoya: A modified lumber that is becoming the gold requirement for duration repairs. It is CO2 neutral and withstands rot and warping for years.Metal (The Industrial Choice)
