6 Major Signs You Need To Replace Your Double-Glazed Windows
Double-glazed windows are popular in areas with colder climates as they provide an extra layer of insulation that can help reduce energy bills. Not only that but they are also known for providing better sound proofing and reducing outside noise. However, double-glazed windows are not designed to last forever, and over time they can start to show signs that they need replacing.
If you are one of these people who are not sure whether it's time to replace your double-glazed windows, then this blog is for you. Here, we will discuss what double-glazed windows are, the 6 major signs that indicate you need to get them replaced, as well as the key things that you should remember when replacing them.
Through this blog, we will help you make an informed decision on whether it's time to replace your double-glazed windows. This way, you can promptly begin your search for the best glazier services in Canberra.
What is a double-glazed window?
Double-glazed windows, also referred to as double-glazing, comprise of two separate glass panes, which are separated by a gap containing an inert gas such as Argon. This arrangement provides insulation that is designed to minimise heat loss through the window as well as reduce noise from the outside.
Significantly, double glazing provides several benefits that single-glazing does not, such as improved insulation, temperature control, and soundproofing. Unlike single-glazed windows that do not provide enough insulation, double-glazed windows are designed to provide high thermal efficiency, keeping the inside temperature more stable during hot and cold weather. Hence with double glazing, heat loss can potentially be cut by half under ideal conditions.
How do I know if my double-glazed windows need replacing?
In some households, window replacement is typically determined by the age of the existing windows. Typically, when double-glazed windows reach 15-20 years old, they may require replacement. However, this may not always be the case as sometimes, they may already need replacement even after a few years of installation. While determining the lifespan of your existing setup could pose a challenge, there are also other factors aside from age that can affect the condition of your windows.
Here are 6 major signs you should look out for if you think your double-glazed windows may be in need of replacement:
1. Condensation
One of the primary indicators that it may be time to consider window replacement is the presence of condensation forming between the panes of your double glazing. When the temperature of your glass windows drops below its dew point, the water vapor in the air will condense and form water droplets on the surface of your windows.
Therefore, as soon as you notice that moisture accumulates between the two window panes, it can then suggest that the edge seal of your window might have deteriorated. Another sign that you should also check is when it has when it seems cloudy whenever you look through your windows.
Furthermore, high condensation levels can lead to cold and muggy rooms in your property, indicating that the window panes may have developed a leak. If you observe condensation between the panes of your windows, it's crucial to consider a double-glazing window replacement as soon as possible.
2. Draughty Windows and Doors
Window hinges basically allow windows to open and close properly. However, once they fail or wear out, draughts will start to enter through the gaps in the window frame.
Draughts in double glazing windows and doors are often caused by faulty hinges. While draughts from the windows indicate that the seals have worn away, draughts from the gap between your property's windows suggest the sealants may have deteriorated. Whatever the cause is, draughty double glazing windows can be a major source of discomfort and energy loss in your home.
Some common things that you may notice from your draughty windows include amplified outside noise, colder air during winter, and increased heat during summer.
3. Water Leak
Aside from insulation and noise reduction, double-glazed windows are designed to protect your home from weather conditions like rain and snow. So if you start to notice water leaks in or around your windows, then it could indicate that something is wrong with your double glazing.
Water leaks commonly occur when the seal of your window frames has been damaged or has worn away. However, if the problem is not in the window seals, then it can be a blockage in your window's drainage. If water leaks have started to occur, you might want to replace your double-glazed windows quickly to prevent flooding and further damage to your home.
4. Chips and Cracks
The presence of a chip or crack in the window panes is a clear indication that your double-glazing window may already need replacement. As you know, chips and cracks may not only weaken your windows but they can also affect your cooling systems.
A crack in the window pane basically allows outside air to come inside your house, which can cause your cooling systems to work harder than they should. As a result, your power bills can get too high and make the problem even worse. The best solution is to replace windows as soon as possible to prevent further problems from arising.
5. High Energy Bills
Energy efficiency is one of the primary advantages offered by double glazing windows. However, due to various factors, your windows may start to become less energy efficient. If you find yourself paying more on your usual energy bills or certain areas of your home are noticeably colder than others, then it clearly indicates that your property is losing heat through its windows.
Replacing windows is one of the most effective ways to improve your energy efficiency. Considering the importance of minimising your expenses, choosing to invest in new double-glazed windows becomes a valuable decision, particularly if you aim for long-term benefits.
6. Amplified Exterior Noise
Double-glazed windows consist of two panes of glass that are designed to absorb sound vibrations and reduce noise from the outside. Unlike single-glazed windows that only offer limited noise reduction, double-glazed windows have the ability to reduce sound by 20 to 65%, which is equivalent to 35 decibels.
So if you find that noise from outside is already getting louder and louder, then it could be a sign that your double glazing is not working properly anymore and need to be replaced.
Can you just replace the glass in double glazing?
While most people believe that replacing glass involves replacing the whole windows and doors, it is actually the opposite. In reality, you can actually replace the glass alone without having to buy an entirely new window frame. This applies to both double-glazed windows and double-glazed doors.
Can you replace a double-glazed window from inside?
If you are installing double-glazed windows and your window frames are already in place, the glass panes should be fitted from the same side as the original beading was, regardless. Glass frames usually have a glazing rebate, which is a notch created to provide a space for fixing the glass from the outside.
The presence of a glazing rebate in frames necessitates careful matching of the glazing panes against this area. As a result, externally beaded frames must be fitted from outside, while internally beaded frames require fitting from inside the home.
How often do double-glazed windows need to be replaced?
Double-glazed windows are generally stronger and more durable than other types of windows. Having an average lifespan of 25 to 30 years or more, double glazing generally last longer than single-glazed windows and regular windows.
As long as your double-glazed windows do not show any of the signs stated above, replacement is not necessary. However, it is important to carry out regular maintenance every few years in order to keep them working as designed for a longer life span. This involves checking the window frames and seals for any damage, making sure they are still secured in place and that all parts are working properly.
Is it worth replacing old double-glazed windows?
Replacing your double-glazed windows with a new glass can surely be a worthwhile investment. By switching out old double glazing with newer glass panels, you can significantly cut down on heat loss an enhance your energy efficiency by as much as 25%.
This contributes greatly in lowering your energy bills while maintaining your home's warmth in the winter and coolness during summer. Moreover, new double glazing windows will also protect your home from external noise.
Takeaway
Double-glazed windows and other double glazing products such as door systems are generally designed to help improve the energy efficiency of a home. Compared to single-glazed windows that only offer basic insulation, double glazing provides an improved level of thermal insulation while blocking out external noise.
If you find that your double-glazed windows are no longer working as effectively as they used to, replacing them may be a worthwhile investment. Some of the major signs to look out for include visible condensation, draughts, water leak, chips and cracks through the windows as well as high energy costs and increased outside noise.
If you are experiencing one of these signs, consider replacing your double glazing windows as soon as possible. With improved insulation and durability, new double glazing will not only help reduce your energy bills but you can also increase the comfort level of your home.
