The Importance of Custom Glazing
Modern custom-made sash windows often make use of "Slimline" double glazing. This innovation enables for a vacuum or gas-filled area between 2 thin sheets of glass, supplying the thermal benefits of modern windows while keeping the thin profile of initial single-glazed panes.

Georgian (Six-over-Six): Characterized by lots of small panes separated by thick glazing bars, reflecting the duration's inability to manufacture large sheets of glass.Victorian (Two-over-Two): As glass manufacturing enhanced, panes ended up being larger. Ornamental sash horns were presented throughout this era for structural stability.Edwardian (Six-over-One): Often included a multi-paned leading sash and a single-pane bottom sash, enabling more natural light.Custom Features and Hardware
