Double glazing has become a popular choice for UK homeowners seeking to improve energy efficiency, reduce noise, and enhance home security. But a common question many people ask is, “How long does double glazing last?” In this guide, we’ll explore the typical lifespan of double glazing, factors that impact its durability, and tips for maintaining it for the long term.
How Long Does Double Glazing Last?
On average, quality double glazing can last anywhere between 20 to 35 years, depending on various factors like the quality of materials, installation, and maintenance. Some high-end double-glazed windows may even last beyond 35 years with proper care. However, there are several elements that influence this lifespan, and it’s essential to be aware of them.
Factors That Affect the Longevity of Double Glazing
1. Quality of Materials
The type of materials used in your double glazing will significantly affect how long it lasts. For example, uPVC frames tend to last around 20-25 years, while aluminium frames might offer greater durability. The quality of the glass, seals, and gas used between the panes (commonly argon) will also play a role in how long your windows remain effective.
2. Installation Quality
Even the best materials won’t perform as expected if they aren’t installed properly. Poor installation can lead to draughts, condensation, and even early deterioration of the window seals. To ensure the best results, it’s vital to hire a trusted professional, such as Cove Glass, who specialises in expert double glazing installation.
3. Maintenance
Routine maintenance can greatly extend the life of your double glazing. Regularly checking the seals, cleaning the frames, and ensuring there’s no water ingress can help prevent damage. Additionally, any small issues, such as broken seals, should be addressed immediately to avoid costly repairs down the line.
Signs Your Double Glazing May Need Replacing
Even with proper care, there will come a time when double glazing reaches the end of its life. Here are some signs to look out for that indicate it may be time for a replacement:
- Condensation Between the Panes: This suggests the seal has failed, allowing moisture to seep between the glass layers.
- Draughts: If you feel cold air coming through, it’s likely that the windows are no longer sealing properly.
- Fading or Discolouration: Over time, UV light can cause some window frames to discolour, particularly uPVC frames.
- Difficulty Opening or Closing: Warping of the frame or damage to the locking mechanisms can indicate that the window is past its prime.
If you notice any of these issues, it may be worth consulting a professional to assess the state of your double glazing.
How to Maximise the Lifespan of Double Glazing
While double glazing is built to last, taking care of your windows can help them reach or even exceed their expected lifespan. Here are some maintenance tips:
- Clean the frames and glass regularly: Dust and grime can damage seals over time.
- Inspect the seals: Ensure they are intact and not showing signs of wear.
- Lubricate the hinges and locks: Keeping the hardware in good condition can prevent mechanical failures.
- Avoid harsh chemicals: Use mild detergents or specialist cleaners designed for uPVC or aluminium.
By following these steps, you can help ensure that your double-glazed windows remain in top condition for many years to come.
