What Are Sash Windows?
Sash windows were, traditionally, single-pane systems. These windows work, traditionally, by sliding one sash over another to open and close. Sash window systems are evident in many traditional and classic buildings; however, it is a style that has translated well into the modern age.
However, one of the significant differences nowadays is that sash windows use more than one sheet of glass. It is common for you to see double-glazed windows in London and elsewhere. Double and triple glazing are modern window standards we feel all homes can benefit from. While traditional sash used by UK homes in the past may have served a practical use, they may not have offered the most comfort and warmth.
Therefore, as a leading specialist in London, we blend the best of the old and the new. We take traditional sash window design’s simple, space-saving practicality and introduce modern comforts and standards. This way, homes can benefit from the stunning, customisable looks of a sash window while getting all the warmth and comfort benefits of the modern era. Our window innovations lead the way in terms of flexible, practical design. Let’s take a closer look at some of our available options.
Two Systems for Sash Window Operation
We offer two traditional methods for operating timber sash windows, ensuring that you can select the best option for your building’s requirements while preserving its historic integrity:
- Spiral Balance System
The spiral balance system is a modern alternative to the traditional sash cord and weights system, often used in new buildings or where there isn’t enough space to fit large boxes that house sash weights.
-
- Space-efficient: Ideal for buildings where space constraints make the traditional cord and weight system impractical.
- Economical: The spiral balance system was introduced in the 1980s as a more affordable, yet still highly functional, solution.
- Operation: The sashes are fixed to a spring tension spiral, operating on friction for smooth and efficient movement. Despite its modern mechanics, the spiral balance system retains the traditional charm and character of a classic timber sash window.
- Sash Cord and Weights System
The sash cord and weights system is the classic design, featuring traditional pulley wheels and steel or lead weights to help the sashes open and close smoothly.- Traditional Appeal: This system remains a popular choice for period properties, preserving the original aesthetic and operation of historic buildings.
- Smooth Operation: The system uses nylon cords on self-lubricating ball-bearing pulley wheels to ensure effortless sliding of the top and bottom sashes.
- Classic Look: This method is particularly suited to stone or brick new-built mansions and prestigious refurbishments, where maintaining the period charm is essential.
