The Victorian age saw a dramatic shift due to the repeal of the Window Tax in 1851 and the development of plate glass. House owners no longer required to take full advantage of little panes; rather, they favored larger, heavier sheets of glass. This caused the "two-over-two" Sash Window Refurbishment style.

For centuries, timber was the undeniable king of window building. Nevertheless, the 20th and 21st centuries have actually presented brand-new materials that attempt to reproduce the look of wood with less maintenance.
Timber (The Heritage Choice)Hardwood: Oak and Mahogany use unbelievable resilience however come at a premium cost.Slow-grown Softwood: Often utilized in initial windows, though contemporary fast-grown pine is less resilient.Accoya: A modified wood that is ending up being the gold requirement for period remediations. It is CO2 neutral and resists rot and warping for decades.Metal (The Industrial Choice)
During the late 19th and early 20th centuries, steel-framed windows-- most especially Crittall-- became popular. These provide a slim, industrial profile that is extremely searched for in Art Deco and mid-century homes.
uPVC (The Modern Substitute)
While traditional uPVC is typically prevented in duration properties due to its "flat" appearance and large frames, "Timber Sash Windows-alternative" uPVC is now manufactured.

Restoration vs. Replacement: The Preservation Dilemma
When dealing with original windows that are draughty or rotting, the first instinct might be to replace them. However, in the context of duration properties, restoration is often the chosen-- and often legally needed-- path.

Nevertheless, innovation has evolved. Vacuum Glazing (such as Fineo or LandVac) offers the thermal performance of triple glazing however is just 6mm to 10mm thick, enabling it to suit conventional thin frames.
Upkeep Checklist for Period Windows
