The Georgian duration is associated with proportion and percentage. During this time, the Sliding Sash Window Company sash window became the standard. Early Georgian windows included thick glazing bars and little panes of glass (usually a "six-over-six" configuration) since big sheets of glass were technically difficult to make. As the period advanced and glass-making methods improved, glazing bars became thinner and more classy.
2. The Victorian Era (1837-- 1901)
The Victorian era saw a remarkable shift due to the repeal of the Window Tax in 1851 and the development of plate glass. House owners no longer required to optimize small panes; rather, they favored bigger, much heavier sheets of glass. This led to the "two-over-two" sash design. To support the weight of the much heavier glass, Victorian contractors presented "sash horns"-- ornamental lugs on the side of the sashes that supplied structural support.
3. The Edwardian Era (1901-- 1914)
Edwardian architecture was a response to the perceived gloominess of the Victorian period.

For centuries, timber was the undisputed king of window construction. Nevertheless, the 20th and 21st centuries have actually presented brand-new products that try to reproduce the look of wood with less maintenance.
Timber (The Heritage Choice)Hardwood: Oak and Mahogany provide extraordinary toughness however come at a premium rate.Slow-grown Softwood: Often used in initial windows, though modern-day fast-grown pine is less durable.Accoya: A modified wood that is becoming the gold requirement for period restorations. It is CO2 neutral and withstands rot and warping for decades.Metal (The Industrial Choice)
During the late 19th and early 20th centuries, steel-framed windows-- most significantly Crittall-- became popular. These offer a slim, industrial profile that is highly searched for in Art Deco and mid-century homes.
uPVC (The Modern Substitute)
While standard uPVC is generally avoided in duration residential or commercial properties due to its "flat" appearance and bulky frames, "timber-alternative" uPVC is now manufactured. These feature mechanical joints and wood-grain textures to mimic the appearance of real wood, though they are seldom permitted in listed buildings.
Repair vs. Replacement: The Preservation Dilemma
When dealing with initial windows that are draughty or decomposing, the very first instinct might be to replace them. However, in the context of duration homes, restoration is frequently the chosen-- and in some cases lawfully needed-- path.

These get rid of "allowed development rights," indicating preparation permission is needed to change any windows that face a highway or public area.The Double Glazing Challenge
Historically, double glazing was prohibited in many period homes because the thick "sealed systems" required heavy glazing bars that messed up the window's slim profile. Nevertheless, technology has actually evolved. Vacuum Glazing (such as Fineo or LandVac) provides the thermal performance of triple glazing but is only 6mm to 10mm thick, permitting it to fit into standard thin frames.
Maintenance Checklist for Period Windows
