Sash window horns, also known as sash horns or sash ears, are decorative extensions located at the bottom corners of double-hung sash windows. These features have a rich history dating back to the 17th century, originating in England during the Georgian and Victorian eras.
In the 17th century, the classic double-hung sash window design emerged in England, allowing for better ventilation and natural light in buildings. The sash horns were added to the bottom corners of the window frames to provide additional support and stability to the sashes. These horns prevented the lower sash from being opened too wide, ensuring that the window remained structurally sound.
As architectural styles evolved, sash windows with decorative horns became popular in Georgian and Victorian buildings. During the Georgian era (1714-1837), windows were often characterized by symmetrical designs and proportioned layouts. Sash horns, with their elegant and ornate appearance, complemented the overall aesthetic of Georgian architecture.
In the Victorian era (1837-1901), sash horns continued to be a prominent feature in windows. Victorian architecture embraced elaborate and decorative elements, and sash horns were no exception. These horns were often intricately carved and embellished, reflecting the elaborate style of the time.
With advancements in window manufacturing and architectural styles changing in the 20th century, the use of sash horns became less common. However, they remain a distinctive feature in historical buildings and period-style architecture, showcasing the craftsmanship and attention to detail of past eras.
Today, sash window horns are still appreciated for their historical significance and aesthetic appeal. They serve as a reminder of traditional architectural styles and continue to be replicated in restoration projects, preserving the charm of historical buildings for generations to come.

The Necessity of Sash Horns in Traditional Windows
Sash Window Horns were initially employed in timber sash windows to reinforce the window’s structure by supporting the mortice and tenon joints. They prevented the sashes from opening too wide and getting stuck. During the Victorian era, architects desired larger glass panes and eliminating glazing bars necessitated a new support method, leading to the creation of sash horns.
Careful observation of Victorian-period properties reveals these distinctive features on sash windows. They were crafted in various shapes to align with architectural trends, ranging from simple curves to intricate designs such as ‘s’ shapes, inverted slopes, or combinations of insets and protrusions. Today, these sash horns serve as representative symbols of the Victorian style and are essential elements in the restoration of heritage properties.
