How to fix blown double glazing
If you have noticed condensation or misting inside the glass of your double glazed windows, it is likely that your windows have “blown”. Blown double glazing occurs when the seal between the glass panes deteriorates, allowing moisture to enter and compromise the insulating properties of the windows. However, don’t worry! Fixing blown double glazing can be a relatively straightforward process.
Firstly, it is important to identify which of your windows are affected by blown double glazing. Look out for signs of condensation, fogging, or a cloudy appearance between the glass panes. Once you have located the affected windows, you can proceed with the repair process.
Sometimes, a blown double glazed unit can be fixed by simply replacing the glass panes while keeping the existing frames. This process involves removing the faulty glass unit and replacing it with a new one. It is essential to use a professional glazing company for this task, as they will have the necessary expertise and tools to ensure a high-quality replacement.
In some cases, it may be more cost-effective to replace the entire double glazed window instead of just the glass unit. This option can be particularly beneficial if your windows are older or in poor condition overall. Replacing the entire window unit ensures that you have a new, fully sealed system that will provide better energy efficiency and insulation for your home.
Remember, prevention is better than cure! To avoid blown double glazing in the future, it is important to regularly inspect and maintain your windows. Keep an eye out for any signs of deterioration or damage to the window frames, such as cracks or gaps. Additionally, ensure that the weatherstripping and seals around the windows are in good condition. By taking these preventive measures, you can prolong the lifespan of your double glazed windows and avoid the hassle of dealing with blown double glazing.
In conclusion, if you have blown double glazing, don’t panic! Identifying the affected windows and contacting a professional glazing company will help you find the most suitable solution. Whether it’s replacing the glass unit or the entire window, fixing blown double glazing will restore the insulation properties of your windows and contribute to the overall comfort and energy efficiency of your home.
What Causes Double Glazing to Blow
Double glazing refers to windows that are made with two panes of glass, with a layer of air or gas between them. It is a popular choice for windows due to its thermal insulation properties and ability to reduce noise. However, over time, double glazing can “blow,” which means that condensation or moisture can build up between the glass panes, causing them to appear misty or cloudy.
There are several factors that can lead to double glazing blowing:
- Poor installation: If the double glazing units were not sealed properly during installation, it can allow moisture to enter and cause the windows to blow over time.
- Aging and wear: Over time, the seals around the double glazing units can degrade or become damaged, allowing moisture to penetrate between the panes.
- Extreme temperatures: Rapid changes in temperature, such as cold weather outside and warm heating inside, can cause the sealant and glass to expand and contract, leading to gaps that allow moisture to enter.
- Physical damage: Accidental knocks or impacts to the windows can cause the seals to break or the glass to crack, which can allow moisture to seep in.
It is important to address blown double glazing as soon as possible to prevent further damage and maintain the energy efficiency of your windows. Seeking professional help can ensure that the issue is correctly identified and resolved.
Understanding the Factors Behind Blown Double Glazing
Double glazing is an energy-efficient and cost-effective solution for insulating your home against noise and extreme weather conditions. However, over time, double glazing can become “blown” or “misted,” reducing its efficiency and compromising the comfort levels in your home.
Blown double glazing occurs when the seal between the two layers of glass becomes defective, allowing moisture to enter and condense inside the unit. This results in a cloudy appearance and reduces the insulating properties of the glazing.
Several factors contribute to the occurrence of blown double glazing:
| Factor | Description |
|---|---|
| Moisture | Excess moisture in the atmosphere can penetrate through the seal and cause condensation, especially in homes located in areas with high humidity levels. |
| Age | Double glazing units that have been in place for a long time are more prone to becoming blown as the seals naturally deteriorate over time. |
| Poor Installation | Improper installation techniques or the use of substandard materials can compromise the integrity of the seal, increasing the risk of blown double glazing. |
If you notice signs of blown double glazing, such as condensation or a misty appearance between the glass panes, it is essential to take prompt action to rectify the issue. Ignoring the problem can lead to further damage and higher energy bills.
In many cases, it is possible to repair the blown double glazing without the need for a costly replacement. However, it is recommended to consult a professional glazier who can assess the extent of the damage and provide the most suitable solution.
Regular maintenance and inspections can help prevent blown double glazing by detecting any early signs of deterioration in the seals. This allows for timely repairs or replacement before the issue worsens.
By understanding the factors that contribute to blown double glazing, you can take proactive measures to minimize the risk and ensure the longevity of your window units. Maintaining a well-sealed and properly installed double glazing system will not only enhance your home’s energy efficiency but also enhance its overall comfort and value.
When to Consider Repairing Blown Double Glazing
If you have noticed foggy condensation or visible moisture buildup between the panes of your double-glazed windows, it is likely that your windows have become blown. Blown double glazing occurs when the seals between the glass panes fail, allowing air and moisture to enter the space between them. While blown double glazing may not seem like a major issue, it can cause several problems that may necessitate repair.
Decreased energy efficiency: Blown double glazing can lead to a significant decrease in energy efficiency. The presence of moisture and air between the glass panes disrupts the insulating properties of the window, resulting in heat loss during colder months and reduced cooling efficiency in warmer months. This can cause your energy bills to increase as your HVAC systems have to work harder to maintain a comfortable temperature.
Aesthetic impact: Blown double glazing can also affect the overall appearance of your windows. The condensation and moisture buildup creates an unsightly fog or haze that obstructs your view, making your windows appear dull and unattractive. This can detract from the curb appeal of your home and potentially lower its value.
Internal damage: In addition to the aesthetic impact, the moisture trapped between the glass panes can also lead to further damage. Over time, the moisture can seep into the frames or cause the wooden components to rot, potentially compromising the structural integrity of the windows. This can be particularly problematic if you live in an area with high levels of humidity or frequent rainfall.
Depending on the severity of the blown double glazing and the extent of the damage, it may be worth considering repairs. Professional glass technicians can assess the condition of your windows and advise on the best course of action. In some cases, the failed seals can be replaced, restoring the integrity and functionality of the double glazing. However, if the damage is extensive, it may be more cost-effective to replace the entire window unit.
It is important to address blown double glazing promptly to prevent further damage and maintain the energy efficiency and aesthetic appeal of your windows.
Signs It’s Time to Fix Your Blown Double Glazing
Double glazing is a popular choice for windows and doors due to its energy efficiency and sound insulation properties. However, over time, the seals between the two glass panes can fail, causing the glazing to “blow” or become foggy and filled with condensation. It’s important to fix blown double glazing promptly to prevent further damage and maintain the benefits of your windows or doors.
1. Foggy or Condensation-Filled Windows
If you notice foggy or condensation-filled windows, it’s a clear sign that your double glazing has blown. This occurs when the seals fail, allowing moisture to penetrate between the glass panes. The presence of condensation can reduce the visibility through the window, making it difficult to enjoy a clear view of the outside world.
2. Drafts and Cold Spots
Blown double glazing can lead to drafts and cold spots in your home. As the seals deteriorate, air can seep through the gaps, compromising the insulation properties of the windows or doors. This can result in uncomfortable drafts and cooler areas near the affected double glazing. Not only does this decrease the comfort of the living space, but it also increases energy consumption as heating systems work harder to compensate for the heat loss.
If you notice any of these signs, it’s important to consult a professional to fix your blown double glazing. They can assess the extent of the damage and recommend the best course of action, which may involve repair or replacement of the faulty units. Delaying the necessary repairs can lead to further damage and higher energy costs, so addressing the issue promptly is essential for preserving the efficiency and effectiveness of your double glazed windows or doors.
DIY Solutions for Fixing Blown Double Glazing
If you have noticed condensation between the panes of your double glazed windows, it may be a sign that the window seals have failed and the window has become ‘blown’. While professional repairs may be necessary in some cases, there are also a few DIY solutions that you can try to fix blown double glazing. Here are some tips to get started:
1. Replace the Silicone Sealant
One common cause of blown double glazing is the deterioration of the silicone sealant that holds the window panes together.

If the problem persists or worsens, it is recommended to consult with a professional glazing specialist. They will be able to assess the situation and advise you on the best course of action to restore the functionality and appearance of your windows. Remember to consider your safety and experience level when attempting DIY repairs, and always prioritize professional help if needed.
By taking the necessary steps to address blown double glazing, you can improve the efficiency and longevity of your windows while also enhancing the overall comfort and aesthetics of your home.
