As glass manufacturing enhanced, larger panes became possible, and "horns" were added to the sashes to support the weight of the much heavier glass.Edwardian (1901-- 1910): Often utilized a "multi-light" upper sash over a single large pane in the lower sash, permitting an abundance of natural light.Table 2: Custom Design Features by EraFeatureGeorgian StyleVictorian StyleEdwardian StylePane Layout6 over 6 or 8 over 82 over 2 or 2 over 1Multi-pane top over 1 pane bottomGlazing BarsThin and fragileThicker and more robustDiffered, typically decorativeSash HornsUnusualTypical (Functional)Common (Decorative)Common WoodOak or High-grade PinePitch Pine or MahoganyTimber with painted finishesThe Mechanics of Custom Sash Windows

They enable for slimmer "non-box" frames, making them perfect for modern-day openings where a traditional deep box frame won't fit.Performance and Energy Efficiency
A typical mistaken belief is that sash windows are naturally drafty. Customized sash windows negate this through accuracy engineering. Modern bespoke systems include:
Slimline Double Glazing: Designed specifically for heritage windows, this supplies the thermal benefits of contemporary glass while keeping the profile thin sufficient to appear like single glazing.Weatherstripping: Integrated brush seals and rubber gaskets are hidden within the custom-made profiles to avoid air leak and rattling.Acoustic Glass: For homes on busy streets, custom windows can be fitted with laminated acoustic glass to substantially decrease sound pollution.Factors To Consider for Conservation Areas and Listed Buildings
