5 Signs of a Blown Window
If your windows are looking foggy or you’re starting to feel a cold draught, it could be a sign of a blown window. At Totalseal Repairs, we are a leading double glazing repair Glasgow company, and we’ve seen it all when it comes to double glazing problems, and we know how frustrating it can be. But don’t worry, you don’t need to replace the entire window. With our expertise, we can often fix the problem quickly and cost-effectively by simply replacing the sealed unit. Let’s walk you through the key signs of a blown window and how we can help get it sorted.
1. Condensation between the panes
The most obvious sign of a blown window is condensation forming between the two panes of glass. Double-glazed windows are designed to be sealed units, trapping an insulating layer of gas, such as argon, between the panes. This keeps your home warm and improves energy efficiency. However, when the seal is broken, that insulating layer of gas escapes, allowing moisture to enter. This is the answer to the question of “what are blown windows?” and the result is condensation or mist forming between the glass layers. No amount of cleaning the interior or exterior will solve the issue since the moisture is trapped inside.
Once condensation forms, it becomes a clear visual indication that the window is no longer functioning correctly. This moisture can also worsen over time, especially in humid environments, leading to further damage to the window.
2. Misted or cloudy glass
In addition to condensation, you may notice a general misted or cloudy appearance on your window. This occurs as moisture gets trapped between the panes and is often coupled with a foggy view. Misting is not only unsightly, but it also means that the thermal performance of your window is compromised.
The cloudiness can increase in visibility as more moisture collects between the panes, especially after wet weather. This persistent foggy appearance indicates that your window is no longer effectively insulating your home.
3. Draughts around the window
A less visual but equally problematic sign of a blown window is feeling a draught coming through. Double-glazed windows should act as a barrier against external weather, but when the seal breaks, cold air can slip through the gaps. You may feel an uncomfortable breeze near the window even when it’s tightly closed. Draughts not only make your home feel chillier but also force your heating system to work harder, leading to increased energy bills.
If you find that your room feels colder than usual, particularly near windows, it’s a strong indicator that the seal is no longer intact, and you may have a blown window.
4. Increased energy bills
Blown windows can have a significant impact on your home’s energy efficiency. One of the main benefits of double-glazing is its ability to trap heat inside, keeping your home warm in the winter and cool in the summer. When the seal between the panes is compromised, that insulating effect is lost, leading to heat escaping in colder months or more heat entering in the summer.
As a result, you may find that your heating or cooling system has to work harder to maintain a comfortable temperature, leading to an unexpected rise in your energy bills. If you’ve noticed an increase in your energy costs without making any major changes in usage, blown windows could be part of the problem.
5. Visible damage to the seals or frame
Sometimes the problem is visible on the outside of the window. You might notice that the seals around the edges of the glass look cracked, peeling, or damaged. This physical wear and tear are clear signs that the seal has failed, which is allowing air and moisture to pass through. The frames of older windows may also show signs of warping, which can put additional strain on the seals and lead to blowouts.
If you can see visible signs of damage to the seals or frames, it’s essential to have them checked as soon as possible, as leaving blown windows untreated can lead to more significant structural issues.
How to fix blown windows
If you’ve spotted any of these signs, the good news is that blown windows can often be repaired without replacing the entire window. In most cases, the sealed unit (the two panes of glass) can be replaced while keeping the existing window frame intact. This solution is much more cost-effective than a full window replacement and restores the insulation and clarity of your windows.
At Totalseal Repairs, we specialise in repairing blown windows by replacing just the sealed glass unit. After all, it is this which is the key to how double glazing works. Our expert team will assess your windows and recommend the most effective solution to restore both function and appearance. Whether you’re dealing with condensation, draughts, or rising energy costs, we’re here to help.
