The Victorian age saw a significant shift due to the repeal of the Window Tax in 1851 and the creation of plate glass. House owners no longer required to optimize little panes; rather, they preferred larger, much heavier sheets of glass. This resulted in the "two-over-two" sash design. To support the weight of the heavier glass, Victorian contractors introduced "sash horns"-- decorative lugs on the side of the sashes that offered structural reinforcement.
3. The Edwardian Era (1901-- 1914)

For centuries, wood was the undeniable king of Window Restoration Services building. Nevertheless, the 20th and 21st centuries have actually introduced new products that try to reproduce the look of wood with less upkeep.
Wood (The Heritage Choice)Hardwood: Oak and Mahogany provide amazing resilience but come at a premium rate.Slow-grown Softwood: Often used in original windows, though modern-day fast-grown pine is less long lasting.Accoya: A modified timber that is ending up being the gold requirement for duration repairs. It is CO2 neutral and withstands rot and warping for decades.Metal (The Industrial Choice)

Nevertheless, technology has developed. Vacuum Glazing (such as Fineo or LandVac) provides the thermal efficiency of triple glazing but is just 6mm to 10mm thick, enabling it to fit into standard thin frames.
