For many, Accoya wood is the gold standard for customized sash windows. It is a chemically customized softwood that uses stability and resilience going beyond that of the majority of hardwoods, guaranteeing the sashes do not warp or swell-- a common problem with older timber windows.
The Importance of Custom Glazing
Modern custom sash windows frequently use "Slimline" double glazing. This technology permits a vacuum or gas-filled area between two thin sheets of glass, supplying the thermal advantages of modern-day windows while maintaining the thin profile of original single-glazed panes.

Decorative sash horns were introduced during this period for structural stability.Edwardian (Six-over-One): Often featured a multi-paned top sash and a single-pane bottom sash, enabling more natural light.Custom Features and Hardware
Beyond the frame, modification extends to the furniture (hardware). Top quality custom-made sashes usually feature:
Fitch Fasteners: The locking mechanism at the meeting rail.Sash Lifts and D-Handles: Used to pull the bottom sash up.Vent Locks: These enable the window to be locked in a slightly open position for ventilation without jeopardizing security.Surfaces: Options consist of polished brass, antique bronze, satin chrome, or brushed nickel.The Benefits of Professional Installation
