A window sash is a component of the sash window –  a popular type of window that has been used for centuries in homes and buildings all over the world. Sash windows are characterised by their sliding design, which allows them to be opened and closed quickly, providing a source of natural light and fresh air. 

They are known for their aesthetic appeal, historical significance, and versatility, making them a popular choice for many homeowners. However, many older sash windows may not have proper insulation, leading to drafts and energy loss in the home. In order to address this issue, many homeowners are now exploring the possibility of double-glazing sash windows.

If you’re considering your options when upgrading your windows and doors and are interested in sash windows and glazing options, here’s all you need to know to make a more informed decision.

What Exactly is a Window Sash?

A window sash is the moving part of a window that holds the glass or other glazing material in place. It is a frame that slides vertically or horizontally within a larger window frame, allowing the window to open and close. The sash is typically made up of several components, including the stiles, rails, and mullions.

The stiles are the vertical sections of the sash that run from the top to the bottom of the window. The rails are the horizontal sections that run between the stiles, and the mullions are the dividing bars that separate multiple panes of glass within the sash.

In a traditional sash window, there are two sashes, one above the other, that move in opposite directions. When opened, the lower sash slides up, while the upper sash slides down, providing ample ventilation and natural light. At Wideline Windows, we carry sashless windows, too.

Can Window Sashes Be Double Glazed?

The simple answer is yes, sash windows can absolutely be double-glazed. This can be done by removing the original single-paned sash windows and replacing them with double-glazed units – or by adding a secondary glazing unit to the existing sash window.

There are several benefits to double glazing sash windows, including:

  • Increased Energy Efficiency: By reducing heat loss, double glazing can help to improve the energy efficiency of your home. This can result in lower energy bills, as well as a more comfortable living environment.
  • Improved Acoustic Performance: Double glazing can also help to reduce the amount of noise that enters your home, making it ideal for homeowners who live in noisy areas.
  • Enhanced Aesthetic Appeal: Double-glazed sash windows can also add to the aesthetic appeal of your home, as the additional layer of glass can help to enhance the look of the windows.
  • Improved Security: Double glazing also adds an extra layer of security to your home, as it makes it more difficult for intruders to gain access.

When it comes to double-glazing sash windows, there are several options available, including

  • Replacement Units: If you want to completely replace your original sash windows, you can opt for replacement units that are specifically designed for sash windows. These units will fit into your existing window frames and can be customised to match the style and colour of your home.
  • Secondary Glazing: If you want to retain your original sash windows, but still improve their energy efficiency, you can opt for secondary glazing. This involves adding a second layer of glass to the existing windows, which is fitted inside the existing frame.
  • Hybrid Systems: Another option is a hybrid system, which combines the best features of both replacement units and secondary glazing. This system removes the original single-paned sash windows and replaces them with double-glazed units, but retains the original frame.

Regardless of the type of double glazing you choose, it is important to choose a reputable and experienced installer and the right type of windows. This will ensure that your sash windows and window sash are installed properly, and will provide you with maximum energy efficiency and comfort.

How To Maintain Sash Windows

Maintaining sash windows is important to ensure they remain in good condition and operate smoothly for many years. Here are some steps to follow to maintain your sash windows:

  1. Cleaning: Regular cleaning of your sash windows is crucial to remove dirt, grime, and debris that can accumulate over time. Use a soft cloth and mild soap and water to clean the glass and frame of the windows. Avoid using harsh chemicals, which can damage the finish or paint.
  2. Lubrication: Lubricate the moving parts of your sash windows, such as the sash cords, window sash, pulleys, and hinges, to ensure they move smoothly and reduce friction. Use a silicone-based lubricant or a special window-track lubricant, which can be found at most hardware stores.
  3. Painting and Staining: If your sash windows are made of wood, it is important to keep them painted or stained to protect the wood and prevent weather damage. Repaint or restain your windows every few years, as needed.
  4. Repairing Damaged Parts: Check your sash windows regularly for any signs of damage, such as broken glass or cracks in the frame. Repair any damaged parts promptly to prevent further damage and ensure your windows continue to function properly.
  5. Sealing Gaps: If you notice any gaps around your sash windows, you may need to apply a sealant to prevent drafts and improve energy efficiency. Make sure to use a high-quality sealant that is suitable for your windows.

By following these steps, you can keep your sash windows in good condition and enjoy their beauty and functionality for many years. If you encounter any problems or are unsure about how to maintain your sash windows, it is always a good idea to seek the advice of a professional.
