What Are RunThru Horn Windows?

Historical Function of Window Horns

In the past, sash horns were an essential part of timber sash windows. They were designed to:

1. Strengthen the Window Frame: The horns helped to reinforce the joints and prevent the frame from twisting or warping under the weight of the window panes.
2. Support the Sash Mechanism: They provided additional support for the sliding sashes, ensuring smooth operation and durability.

Modern Window Horns With advancements in window manufacturing, the structural necessity of sash horns has diminished, particularly with the use of modern materials like uPVC and aluminium. However, they remain a popular design feature for those looking to maintain or replicate the classic appearance of traditional sash windows.

uPVC RunThru Sash Horns: In contemporary uPVC windows, like those offered by ABS, sash horns are often integrated into the window profile through a process called milling. This means they are moulded as part of the window frame rather than being attached separately. This method:

• Ensures a Seamless Look: The horns appear as a natural extension of the frame, maintaining the aesthetic integrity of traditional sash windows.
• Enhances Durability: With fewer joints and attachments, the risk of parts loosening over time is reduced.

Decorative Appeal

The main appeal of window horns today is decorative. They provide:

• Authentic Period Charm: Ideal for homeowners who wish to retain or restore the traditional look of their property, especially in conservation areas.
• Architectural Interest: The addition of sash horns can add a touch of elegance and detail to both period and contemporary homes.

About ABS uPVC RunThru Sash Horn Windows

ABS uPVC RunThru Sash Horn Windows are designed to replicate the elegant look of traditional sash windows without the maintenance hassles of timber. Unlike traditional vertical sliding windows, the top-hung RunThru sash horns are crafted by milling the profile into shape rather than attaching the horns with screws. This innovative design ensures a seamless appearance, further enhanced by colour-coordinated caps that enclose the exposed ends.

Your Options

ABS offers three distinct configurations for their RunThru Sash Horn Windows, catering to various aesthetic preferences and regulatory requirements:

Option 1

RunThru Horn Top Hung Over a Fixed Pane

This configuration features a top-hung window over a fixed pane, providing a slim and cost-effective alternative to vertical sliding windows. However, it does not comply with Part B of Building Regulations, which pertains to emergency escape and rescue openings. Homeowners should consider Options 2 or 3 if regulatory compliance is required.

 

 

Option 2

RunThru Horn Over Tilt and Turn Inwards Opening Window

This versatile option combines a top-hung casement with a tilt and turn lower sash. The top-hung casement offers ventilation and can be locked in a night ventilation position. The tilt and turn lower sash can be tilted for ventilation or turned 90° inwards for easy cleaning. Additionally, depending on size and position, it can serve as an emergency escape window, meeting Part B of Building Regulations.

 

 

Option 3

Full Tilt and Turn with Dummy Sash and RunThru Horns

Designed for homeowners who prefer the top-hung over fixed pane style but need to meet regulatory requirements, this configuration features a full tilt and turn sash paired with a fixed dummy sash with RunThru horns.
