When it comes to home improvements, double glazing is one of the most popular upgrades homeowners make to improve energy efficiency, enhance security, and reduce noise.
But how long can you expect your double-glazed windows to last?
Read more below to find out how long double glazing lasts.
What Is Double Glazing?
Double glazing is a type of window that has two panes of glass within a single frame. The panes are separated by a gap filled with gas that has a high insulation ability such as argon. This slows the movement of heat from one side of the window to the other keeping your home warm or cool. It also has other benefits such as reducing external noise and improving the security of your home.
How Long Does Double Glazing Last?
On average, modern double glazing can last between 20 and 35 years and possibly even longer with the right maintenance and care. However, some factors outside your control can affect this lifespan. Keep an eye out for these signs as it could mean your windows may need to be replaced.
Factors Affecting the Lifespan of Double Glazing
There are many factors that can affect the lifespan of double glazing including:
Temperature and the Elements
Scotland’s climate is known for its cold winters, wet summers, and frequent storms, which can put extra strain on double-glazed windows. High humidity and the salt from coastal air can cause wear and tear over time, especially if windows are improperly maintained.
While the location of the house can affect the lifespan, the location of the unit itself can also affect it. So, a north facingunit can last longer than a south facing one due to the south being significantly more exposed to the sun. Therefore, two double glazed units in the same house can have different lifespans depending on their exposure to the sun, heat and rain.
Quality of Manufacture and Installation
Not all double-glazed units are created equal. Higher-quality windows tend to last longer than cheaper alternatives. Investing in quality windows can provide your home with reliable insulation and protection for decades.
Even the best double-glazed windows can fail prematurely if not installed correctly. Professional installation is crucial to ensure the windows are sealed properly and the frame is secure. Poor installation can lead to draughts, condensation between panes, and quicker deterioration.
Maintenance
Regular maintenance can extend the life of your double glazing. This includes checking for signs of condensation between the panes, ensuring the window frames are sealed and intact, and cleaning the windows to prevent the build-up of dirt that could affect their performance.
Signs That Your Double Glazing Needs Replacing
While double glazing is designed to last for several decades, there are certain signs to watch out for that indicate it may be time to replace your windows:
- Condensation between the panes: This is often a sign that the seal has failed, allowing moisture to seep in. Condensation on the pane inside is not a concern.
- Drafts and cold spots: If you feel drafts near your windows or notice cold spots, the insulation may no longer be effective. This means the heat will be escaping your home
- Visible damage: If the frames are cracked, warped, or have visible gaps, your windows may not be performing at their best.
- Increased energy bills: If your energy bills suddenly rise, then this may be a sign that there is an issue with your windows.
Still have single glazed windows?
If your home still has single glazed windows then you should consider upgrading to double glazed windows. These windows are not as energy efficient as modern double glazed windows.
How to Maximise the Lifespan of Your Double Glazing
To get the most out of your double-glazed windows, here are some tips for maintenance:
- Inspect seals regularly: Check the seals around your windows for cracks or gaps, and replace them if necessary.
- Clean the glass and frames: Regular cleaning helps maintain the appearance and function of your windows. Avoid harsh chemicals that can damage the frames.
- Keep window frames clear of debris: Ensure that dirt, leaves, and other debris do not accumulate around the window frames, as this can cause damage or reduce efficiency.
- Address minor issues early: If you notice small problems, such as a draft or condensation, it’s best to get them sorted before they develop into bigger issues.
Why is Double Glazing Worth the Investment in Scotland?
For nearly all homeowners, double glazing will be worth the investment. Here are some of the benefits they can offer:
Energy Efficiency
Home energy efficiency is important to homeowners as it can not only keep your home warm but alsoreduce your energy bills.
Double glazed windows can improve your home’s energy efficiency by slowing heat from escaping the home. According to the UK Government, around 18% of heat loss happens through our windows. Heat is lost twice as quickly through single glazing than standard double glazing, around 7% of households in the UK have no double glazing.
Even old double glazed windows may have lost their efficiency costing you more on your energy bills. By upgrading to modern, efficient windows, you can guarantee to save money on your energy bills.
Warmer Home
Double glazing is a worthwhile investment when keeping your home warm. This is due to their energy efficiency meaning less heat will be escaping so your home will stay warmer for longer.
This will not only benefit your home comfort by keeping your home warmer for longer but again this will mean you will be saving money on your energy bills.
But, while double glazing is known to keep your home warm, it can also keep it cool instead. During the summer, double glazing can also keep your home cool by stopping heat from the sun entering the home. This will reduce the need for air conditioning to cool your home down.
Noise Reduction
If you live next to a busy main road or other noisy areas then double glazing will likely be a worthwhile investment for you.
Double glazing is efficient at reducing outside noise. This is due to their high insulation ability that can dampen outside noise more efficiently than single glazed or old double glazed windows.
So, you can enjoy some peace in the comfort of your own home with double glazing.
Security
Double glazed windows can increase your home’s security by offering an extra layer of protection. If you have single glazed windows or old damaged double glazed windows then your home’s security could be compromised.
This is because double glazing has two panes of glass instead of one in a single frame which makesthem harder to break. Old and damaged windows also make your home an easy target for intruders as they are weaker and therefore easier to break.
So, double glazing can be a worthwhile investment for your home’s security.
Increased Property Value
While installing double glazing in your home can be an expensive investment, it can be worthwhile for your home’s value.
Installing new double glazed windows can increase your home’s value and make it more inviting to potential buyers if you plan on selling.
All in all, double glazing will be a worthwhile investment for a majority of homeowners as it comes with a range of benefits for you are your home.
