The Victorian era saw a significant shift due to the repeal of the Window Tax in 1851 and the innovation of plate glass. Homeowners no longer required to take full advantage of little panes; rather, they favored larger, much heavier sheets of glass. This led to the "two-over-two" sash design. To support the weight of the much heavier glass, Victorian home builders introduced "sash horns"-- ornamental lugs on the side of the sashes that offered structural reinforcement.
3. The Edwardian Era (1901-- 1914)

For centuries, lumber was the undisputed king of window building. However, the 20th and 21st centuries have actually presented brand-new products that attempt to replicate the look of wood with less upkeep.
Lumber (The Heritage Choice)Hardwood: Oak and Mahogany offer amazing toughness but come at a premium cost.Slow-grown Softwood: Often used in original windows, though modern fast-grown pine is less resilient.Accoya: A customized wood that is becoming the gold requirement for duration repairs. It is CO2 neutral and resists rot and warping for years.Metal (The Industrial Choice)
During the late 19th and early 20th centuries, steel-framed windows-- most especially Crittall-- became popular. These supply a slim, commercial profile that is extremely searched for in Art Deco and mid-century homes.
uPVC (The Modern Substitute)
While traditional uPVC is usually avoided in duration properties due to its "flat" look and bulky frames, "timber-alternative" uPVC is now made. These feature mechanical joints and wood-grain textures to imitate the appearance of real timber, though they are rarely allowed in listed structures.
Repair vs. Replacement: The Preservation Dilemma
When dealing with original windows that are draughty or decaying, the very first impulse might be to replace them. Nevertheless, in the context of period homes, repair is typically the chosen-- and sometimes lawfully needed-- route.

Historically, double glazing was prohibited in numerous period residential or commercial properties since the thick "sealed systems" needed heavy glazing bars that destroyed the window's slender profile. However, innovation has developed. Vacuum Glazing (such as Fineo or LandVac) offers the thermal performance of triple glazing but is only 6mm to 10mm thick, permitting it to suit standard thin frames.
