Understanding Double Glazing
Double glazing, a popular feature in modern homes consists of two panes of glass separated by an insulating layer of air or gas. This construction enhances energy efficiency, reduces noise transmission, and improves overall comfort within your home. However, over time, the performance and durability of double glazing can decline.
Drawbacks of Old Double Glazing
While old double glazing had its advantages, it also had its limitations. Over time, double glazing can lose its effectiveness due to wear and tear. The seals between the glass panes may deteriorate, leading to air leakage and reduced thermal efficiency. The frames of old double glazing may also become worn, allowing drafts to enter your home.
Benefits of New Double Glazed Windows
Over time, advancements in window technology have led to the development of new and improved windows since it was first introduced in the 1970s.
Investing in new windows offers a range of benefits. Firstly, you can enjoy improved energy efficiency, leading to reduced heating and cooling costs. New windows also enhance the overall appearance of your home, adding value and curb appeal. Modern windows also require less maintenance and offer much higher security features, giving you peace of mind.
How Old is My Double Glazing?
If you’ve recently moved into a new property or can’t recall the last time you replaced your double glazing, the easiest way to determine its age is by visiting the FENSA website. Your window installation contractor should have registered the certification if the windows were fitted after April 2002.
FENSA is a national scheme designed to ensure that window companies are installing windows that meet the minimum building regulation requirements and be issued with a certificate to confirm this.
However, if your windows were not fitted by a registered FENSA company, or it was a DIY job, then the windows should have had full local authority Building Control Approval.
Older Double Glazing (Prior 2002)
If your windows don’t show up through the FENSA scheme or Building Control Approval, chances are that they were installed prior to 2002. uPVC windows can last for 20 or even 30 years, depending on a variety of factors.
If you’re unsure whether your windows need replacing, there are signs that can help you determine the age of your double glazing.
9 Signs That It’s Time to Replace Your Windows
The first step is to determine when your windows were initially installed. Newer installations often come with documentation or guarantees that provide an accurate timeline.
However, if this information is unavailable, other signs can still help you estimate the age of your double glazing, and know when it’s time to replace your windows.
Here are some key things to look out for.
1. Increased Energy Bills
If you notice a significant increase in your energy bills, it could be due to the inefficiency of your windows. Old windows often lack proper insulation, leading to heat loss during winter and heat gain during summer.
Replacing them with newer, more efficient models can help you save on heating and cooling costs in the long run.
2. Condensation and Moisture
Condensation and moisture between the glass panes are common problems with older double glazing that has deteriorated over time.
If you notice foggy or misty windows, it’s a strong indication that the seals have failed and replacement is necessary. Excessive condensation on your windows can indicate poor insulation and can lead to mould growth and damage to the surrounding walls.
3. Drafts and Temperature Fluctuations
If you feel drafts around your windows or notice air leakage even when they are closed, it’s a clear indication that your windows are no longer providing an effective seal. Upgrading to new windows can provide better temperature regulation.
4. UV Damage to Furniture and Flooring
Older windows may lack effective UV protection, causing the sun’s rays to damage your furniture, flooring, and other interior elements.
If you notice fading or discolouration, it’s time to consider replacing your windows with UV-resistant glazing to preserve your belongings.
5. Difficulty Opening, Closing, or Locking Windows
Over time, wear and tear can affect the functionality of your windows. If you’re struggling with opening, closing, or locking them, your windows may have faulty mechanisms or damaged frames which pose a potential security risk.
Installing new windows with smoother operation and robust locking mechanisms will enhance both safety and convenience.
6. Visual Wear and Tear
Cracked glass, rotting frames, or peeling paint are signs of significant window damage. These issues not only affect the aesthetics but also compromise the functionality of the windows.
7. Increased Noise Pollution
If you find that outside noise easily enters your home, it’s a sign that your windows are not soundproof. Upgrading to newer windows can significantly reduce noise infiltration.
8. Outdated Appearance
Old, worn-out windows can significantly detract from the overall aesthetic appeal of your home. By replacing them with modern designs, you can elevate the appearance of your property and potentially increase its value.
9. Enhanced Security
Modern windows come with advanced security features that offer greater protection against unwanted intruders. If your current windows lack these essential security enhancements, it’s wise to invest in replacement windows that prioritise the safety of your home.
Conclusion on How to Tell the Age of Double Glazing
Determining the age of double glazing can be done by visiting the FENSA website, where you can find information about the installation date and related details. This is especially useful for windows installed after April 2002 when contractors were required to register window certifications.
By knowing how to tell the age of double glazing, you can better assess its condition, warranty coverage, and when it might be necessary to consider a replacement.
Old double glazing, while beneficial in the past, can lose its effectiveness over time. Upgrading to new windows offers improved insulation, energy efficiency, and overall comfort.
