Certainly, it is not only possible but also a common practice to install double glazing in wooden windows. The same double-glazing techniques used in plastic or aluminium windows apply to wooden ones as well.
Wooden windows have been equipped with both double and triple glazing for many years. In this blog post, we will provide more detailed information about the process of double-glazing windows.
As a seasoned joinery firm, we were surprised when a client asked, “Can I have double-glazed wooden windows?” However, if one client had this question, it’s likely that others have also wondered about the feasibility and may have overlooked wooden windows altogether.
It’s essential to debunk the misconception that double glazing is exclusive to plastic windows, as wooden windows can also be upgraded with this technology.

What Types of double glazing do we use?
Sash Window Refurbish commonly utilize a double-glazed unit that is 24mm thick, just slightly less than an inch, in the windows displayed above. This specific type of double glazing includes a warm edge spacer bar, argon gas filling the void within the unit, and an energy-saving coating.
The warm edge spacer represents an advancement from the older double glazing, which used metal spacers. Identifying the older and less efficient double glazing is easy as it has a shiny metallic appearance, whereas the modern version boasts a matte finish and effectively minimizes heat loss around the edges.
In addition to the standard units, we also offer slim double-glazed units, as depicted in the image below. These units are specially designed for wooden windows and feature a much smaller spacer bar compared to the regular units we provide.
Typically, these units are only 12mm thick. Similar to the standard units, these slim versions come with a warm edge spacer bar, gas filling the void (usually krypton), and an energy-saving coating. They find their application in heritage settings where slim solid glazing bars are necessary.
Furthermore, there is an innovative product, suitable for situations akin to the slim units. These unique units serve a significant role, especially in wooden windows. We have a sample unit available at our workshop, and we invite potential clients to arrange a visit to personally observe and discuss the promising features these units offer.
Can double-glazed units be replaced?
Double-glazed units have the potential to be replaced without requiring the entire window or joinery item to be changed.
When a double-glazed unit becomes faulty, it does not necessarily mean the entire window structure needs replacement. Historical evidence indicates that wooden windows can endure for a century or even longer. Therefore, there’s no need to panic if a double-glazed unit becomes foggy.
The process of replacing a faulty unit is relatively straightforward. One side of the frame that supports the glass features beading, which can be removed to take out the defective unit and install a new one. While this can be a do-it-yourself task, it is advisable to hire a professional glazing contractor for the job.
What is the Lifespan of Wooden Double-Glazed Windows?
With proper maintenance, the wooden frames of a window can endure for a lifetime. On average, double glazing usually remains effective for about 20 years. We are transitioning to a new glazing method that maximizes the lifespan of double-glazed units.

Tips:
- Assess Your Existing Windows: Before considering double-glazing, evaluate the condition of your existing windows. Don’t invest in double-glazing for windows that are already poor quality or draughty.
- Address Draughts First: Even good windows can have draughts, so fix these issues before adding double-glazing. Draughty windows can significantly reduce the benefits of double-glazing.
- Consider Ventilation: Ensure that the installation won’t hinder your ability to open windows for ventilation in the summer. Some retrofit solutions might restrict window openings, so be cautious.
- Explore Alternatives: Evaluate whether spending on double-glazing is the most cost-effective solution. There might be other home improvement options that provide similar benefits without the hefty price tag.
- Check Window Suitability: Verify if your existing windows are structurally suitable for double-glazing. Older windows may not be strong enough to support the added weight, requiring reinforcements or replacements.
- Properly Adjust Double-Hung Windows: If you have double-hung windows, ensure that the counterweights and balances are adjusted correctly. Use heavy-duty pulleys and reinforced ropes or appropriate spiral balances designed for the weight of double-glazed units.
In essence, before investing in double-glazing, assess your windows’ condition, fix any draught issues, consider ventilation, explore cost-effective alternatives, check window suitability, and ensure proper adjustments for double-hung windows.
