The Benefits of Replacement Double Glazed Units

Double glazing comes with a range of advantages for homeowners, including:

It's cheaper to replace a double-glazed sealed unit instead of the frame of a window with drafty issues. It can also save money on your energy bill. You can also select from a range of colours and styles.

Improved Energy Efficiency

Double glazing can help you save money by reducing the amount warmth and draughts which escape from your home. It also helps you conserve energy, which is beneficial for the environment and your household expenses. It can also improve the value of your home because estate agents claim that houses with double glazing are more appealing to buyers.

In terms of the energy efficiency of a double glazed unit there are a variety of things that can be done to increase its 'R' or insulation value. One option is the use of a different material to construct the frame, like wood or composite rather than metal since it is an effective insulator. A thermal break could be incorporated between the frame and glass panes. This is typically used with argon and can give an R-value of about R-3 to the IG unit. In addition, tinted or colored glass can enhance the insulation of windows as it helps to prevent heat transferring through the surface.

Double glazing can reduce the transfer of heat from your house to the cold outside by at least half. This allows you to keep your home warm during winter and cool in summer without having to increase the temperature.

A double-glazed sealed unit that fails can be upgraded to an "A" rating which makes it more energy-efficient. This will decrease your carbon footprint as well as reduce your the cost of energy.

Condensation is caused by moisture in the air and the resulting water vapour gathers on the surfaces of the glass. glass repair is a natural phenomenon caused by double glazing, which allows a tiny amount of air to circulate between two panes. Once the double-glazed unit is replaced, your windows will perform normal and will not have condensation.

Reduced Condensation

If you notice condensation on your windows, it's a sign that your double glazing is not performing as well as it ought to. In this situation windows need to be resealed. This is a simple task that is well worth the expense. Double-glazed windows that are energy efficient can provide improved insulation, lower costs in addition to a lower level of noise and better value for property.

Condensation occurs when airborne water vapour comes into contact with a cool surface like windowspanes. The moisture adheres to the surface and forms droplets of water which can lead to mould or damp, and even decay. It can also impact the paintwork and wallpaper on the walls of your house. It could also be a sign of poor ventilation.

It's not surprising that condensation can be found in your home because we constantly release water vapour, particularly when we cook and shower. It's a normal part of everyday life and is usually harmless however it can cause problems in some homes.

Double-glazed windows are known to be more effective in getting rid of condensation than single-glazed windows. However, the issue can occur due to factors like changes in the temperature of your home, lack of ventilation, and a variety of environmental factors, such as high humidity.

If you see condensation in the windows you have just installed It's likely that the seal between the glass panes has failed and is permitting water to enter the air gap. This can be due to a variety of reasons, including the age of your double-glazed windows and their construction quality.

Condensation may also show up on your windows if the temperature fluctuates too fast in your home. When you switch on the cooling or heating, the difference in outside and inside temperatures creates a sudden rise in humidity. This increases the amount of water vapour in the air, which can then stick to cold surfaces such as your window.

With the insulation properties of replacement double glazed units, such as low-e or argon-filled glass, can help to reduce the appearance of condensation inside your home since it will allow heat to remain within. You should also ensure that your home is ventilated regularly particularly in cold temperatures.

Reduced Noise

When it is a matter of noise pollution, your windows could be among the most significant culprits. Vibrations from neighbours or traffic leaf blowers can penetrate your home, creating an unwelcoming space. Double glazed units help reduce the noise and provide an environment that is quieter.

The air cavity between the 2 panes and the layer of argon gas within your double glazed window slows down the frequency of sound waves, making it more difficult for them to get into your home. This is why double-glazed windows are a great noise reduction solution, especially in homes close to busy roads or noisy neighbours.

You can select from a variety of options for glass, with a variety of tints, low-e options and various thicknesses. You can choose a thicker glass for better acoustic absorption or a laminated option that is stronger and more secure.

The type of insulation used can also influence the performance and acoustic rating of your windows. Some materials are more effective in reducing noise and others have higher energy ratings. Your FENSA Approved Installer will be able suggest the best double glazing for your home.

The amount of noise that can pass through your windows will depend on the frame and its installation. If the frame is poorly constructed or the seals aren't working, then it can be easier for noise to leak through.

As such frames and installations must be professionally done and of the highest quality. This will ensure the maximum amount noise is prevented from entering your home.

Increased Security

As we know, burglars typically enter homes through windows. Double glazing units, particularly those made from toughened glass are extremely difficult to break. This means that your home is safer. This is especially true if choose a FENSA certified installer to install your replacement double glazing. FENSA certified installers are required to use glass that is impact-resistant, which means it's much harder to break and can shatter into smaller pieces instead of leaving sharp pieces of glass behind. This will safeguard your family from possible injuries caused by broken glass.

There are many signs that your double-glazed windows could be on the verge of failure. You might notice draughts and condensation appear within the window frames or you could be spending a lot more on heating and electricity as your house is not as well-insulated as it could be. If you find any of these problems it is important to book repairs with an FENSA approved installer as soon as you can, to avoid further damage and costly repairs.

When your double glazed unit fails it is often described as a "blown" unit. This occurs when the airtight seal that connects the two panes fails and allows gases that are inert, like Argon to leak out.


It can be caused by various causes, such as ageing or lack of maintenance. Extreme weather conditions, like strong winds or the sun shining brightly could also trigger it.

This can damage the edges of the insulation unit over time. This could cause the seal to weaken, which allows the moisture between the two panes to pass through, leading to condensation and fogging.

To remedy this issue, you can have the sealed unit replaced by a new unit. Ensure that the new sealed unit is the right size for the window frame by measuring it. To do this, you'll have to remove the beads from the frame (which are typically fixed by wedge gaskets) and determine the width, the height and the thickness of the unit that has been sealed. You will require a high-quality pair of calipers to do this as they need to be able to grip the beads with a firm grip for a precise measurement.
