What Is The Reason? Replacement Double Glazed Units Is Fast Becoming The Trendiest Thing Of 2023?
The Benefits of Replacement Double Glazed Units

Double glazing comes with numerous benefits for homeowners, like:

If you have a drafty window that's leaking, it can be cheaper and easier to replace the double glazed unit than to replace the frame. Additionally, repair timber windows could save you money on your energy bills. You can pick from a variety of styles and colours.

Improved Energy Efficiency

Double glazing can help you save money by reducing the amount of heat and draughts that escape from your home. It also helps you save energy, which is beneficial for the environment and your household expenses. Double glazing can enhance the value of a home, as estate agents claim that houses with double-glazed windows that is in good condition will be more attractive to prospective buyers.

There are many ways to boost the energy efficiency of double-glazed units. The frame could be made of wood or composite material instead of metal which is a great insulator. A thermal break can be constructed between the glass panes and the frame. This is typically used with argon and can add an R-value of around R-3 to the IG unit. Finally, tinted or coloured glass can increase the insulation of windows because it prevents heat from transferring across the glass.

Single pane windows allow a large percentage of heat to be transferred from the inside of your home to the cold outside air however double glazing reduces this by at least 50%. This lets you keep warmth inside your home throughout winter and cool in the summer without having to crank up the heating or air conditioning too high.

Another benefit of replacing a failed sealed double-glazed unit is the possibility of upgrading to a higher 'A' rating to make it more energy efficient. This will reduce the carbon footprint of your home and save you money by reducing energy bills.

Condensation occurs when water vapour condenses on the glass's surface because of moisture in the air. This is a natural occurrence caused by double glazing, which allows for a small amount of air to move between two panes. When the double-glazed unit has been replaced, your windows will perform normally and be free of condensation.

Reduced Condensation

If your windows show signs of condensation, it is an indication that the insulation properties of double glazing aren't functioning as they should. In this instance windows will have to be sealed. It's an easy task that'll be well worth the investment. Double-glazed windows that are energy efficient can offer better insulation, lower costs as well as less noise and higher property value.

Condensation occurs when water vapour in the air comes into contact with a cool surface, like a windowpane. The moisture clings to the surface and forms droplets of water that could cause mould damp and decay. It may also affect the paintwork and wallpaper on the walls of your home. It can also indicate poor ventilation in your house.

It's no surprise that condensation forms in your home, since we continuously emit water vapour. This is particularly the case when we shower or cook. It's a normal part of our lives and is generally harmless, but can cause problems for some homes.

As a rule double-glazed windows are more effective in eliminating condensation than single-glazed windows. However, the problem can be recurrent due to factors like a change in the temperature of your house, lack of ventilation, and a variety of environmental factors, like high humidity.

If you notice condensation on your double-glazed windows, the seal between the two panes of glass has likely broken and let water be able to get into the air gap. This could be due to a number of factors, such as age, and the quality of construction of your double glazed windows.

Condensation may also show up on your windows if the temperature fluctuates too rapidly in your home. The difference in temperatures between outside and inside when you switch on your cooling or heating results in a sudden increase in humidity. This increases the amount of water vapour that is in the air. This can then adhere to cold surfaces like your window.

The insulating properties of replacement double-glazed units, like low-e or argon filled glass, will help reduce the appearance of condensation in your home since it allows warmth to remain inside. It is also a good idea to ventilate your home every day, especially when the weather is cold.

Reduced Noise

Noise pollution can be caused by your windows. The vibrations generated by traffic or a neighbor's leaf blower may enter your home and cause an unpleasant environment to live in. Double-glazed units can reduce the noise and provide a quieter living space.

The air cavity between the two panes and the argon gas layer inside your double-glazed window slows down the frequency of sound waves, making it much harder for them to enter your home. Double glazed windows can be a great solution to reduce noise, particularly in areas with noisy roads or neighbors.

Furthermore, you can choose from a wide range of glass options to choose from, including different tints and low e choices and also different thicknesses. You can choose a thicker glass for better absorption of sound, or a laminated option which is stronger and more secure.

The type of insulation used will also affect the acoustic and performance of your windows. Some materials are better at reducing noise, while others have higher energy ratings. Your FENSA Approved Installer will be able suggest the best double glazing for you and your home.


The frame and installation affect the quantity of noise that goes through your windows. If the frame isn't properly insulated or if the seals are failing, it will be easier for sound to pass through.

The frames and the installation must be professionally done and at a high quality. This will ensure that the highest amount of noise is blocked from entering your home.

Increased Security

As we all know, burglars often break into homes through windows. Double glazed units, especially ones made of toughened glass, are very difficult to break. Therefore, your home is more secure. This is especially true when you select the FENSA accredited double glazing contractor to install your replacement windows. FENSA certified installers must utilize glass that is resistant to impact which means it's more difficult to break and will break into smaller pieces instead of leaving sharp shards of glass left behind. This helps keep your family safe from potential injuries from broken glass.

There are many indications that your double-glazing is likely to fail. There could be draughts and condensation forming in the window frames, or you might be spending a lot more on heating and electricity as your house is not as well-insulated as it could be. It is important that you book a repair as soon as you spot any problems to avoid further damage or expensive repairs.

When your double glazed unit fails it is often called a 'blown' unit. This happens when the air seal between the two glass panes is broken which allows the gas inert, such as Argon to escape.

This could be caused by a range of reasons, including the aging process and the lack of maintenance. It can also be caused by extreme weather conditions such as strong winds or the sun shining too brightly.

As time passes, this could result in the edges of the insulating units to be damaged. This can cause the seal to become weaker, allowing water between the two panes to seep through, leading to fogging and condensation.

You can replace the sealed unit with a brand new one to solve this problem. Make sure that the new sealed unit is the correct size for the window frame by measuring it. To do this you will need to take the beads from the frame (which are typically held in place by wedge gaskets) and determine the width, the height and the thickness of the sealed unit. To accomplish this, you'll require a pair of calipers that are able to grip the beads tightly to obtain an accurate measurement.
