Replacing Double Glazed Windows

There are a variety of alternatives to choose from, whether you want uPVC cases or sash made of aluminium. They can be customized to your aesthetic needs and energy efficiency requirements. Modern double glazing offers a variety of benefits such as noise reduction, UV protection and property security thanks to multipoint locking mechanisms.

What can you do if your double-glazed is showing signs of wear?

1. Excessive Condensation

In the winter, when windows and doors are closed, condensation may form inside the glass panes if the air temperature is warmer than the window's surface. This is a natural occurrence that can be prevented by opening windows, improving ventilation more generally, running a dehumidifier and keeping moisture levels low with extractor fans. However, if condensation forms regularly on the interior of your windows this is a sign that the double glazing has failed and it needs replacing as soon as possible.

In contrast, condensation on the outside of your windows is a common event and indicates that the double glazing unit is operating as it should. Condensation on the outside of your windows in the morning is because of the cold glass temperature falling below the dew point of the air surrounding it, causing water vapour to be drawn from the air and into the cold glass, where it condenses. This is aggravated by the presence of plants in your home that produce excessive moisture as well as high humidity.

If you notice condensation appearing within your double glazing, this is a more serious problem and it is a sign that the seal between the two glass panes is broken, allowing warm air from your home to get in while the gas that is used to insulate it is lost. This can cause significant damage to the double glazing and, if left untreated, will significantly impact on the cost of energy.

Having replacement double glazing installed when you first detect this kind of condensation can drastically decrease the likelihood that the problem gets worse, saving your money in the end. It is also a great opportunity to upgrade your double glazing to energy-efficient A-rated windows. This will make your home more comfortable and will lower your utility bills.

2. Wear and tear

Double glazing has many benefits, such as reducing energy bills and reducing noise. However, just like any other item, double glazed windows have a lifespan and it is important to be aware of the indicators that they're reaching the limit of their utility.

One of the most obvious signs is visible condensation. This is due to the difference in temperatures between the two panes. If you notice it, it could be an indication that the window seals have failed.

If the window seal fails, then cold air will be able to enter your home which does more than just waste energy but can also lead to damp and mould, both of which are expensive to fix. Additionally, both damp as well as mould can be harmful to health since they can cause allergens and irritants which can affect the health of your family.

Draughts around your windows are another sign that sealants have begun to wear. This allows external noise to enter your home which can be a major distraction, especially if you live close to a busy road or noisy neighbours. This can affect your ability to work from home, or how peaceful your home feels.

If the windows are not opening and closing smoothly, it's also a sign they need to be replaced. This can be a safety issue if windows do not open when required in an emergency such as a fire and should not be ignored. A professional window installer will be able to evaluate the condition of the windows you have and make recommendations regarding the best option.

3. Draughts

If you've noticed drafts coming through your windows, this is typically a sign that the seals within your double glazing have failed. Sealants are used to keep the glass panes together and help with insulation, but it can be damaged by changes in weather or by simply ageing. This can cause cold air to enter your home, and warm air to escape, leading to the draughts to increase and decrease energy efficiency.

A window frame that is shaped incorrectly and not sealing properly could cause draughts. In the result, moisture could get trapped inside the frame, which could also result in rotting and draughts over time. This is a serious issue and it is essential to have your double glazing replaced as soon as possible to avoid any further problems.

A double-glazed window that has a misty appearance is a sign that the sealed unit has let out or the gas has escaped between the panes. This is a serious problem and needs to be repaired immediately to prevent water entering your property, stopping heat from escaping and reducing the effectiveness of your insulation. If your windows are covered by warranty, you can ask the company to replace them.

Double glazing cracks and chips aren't always a signal of needing to be replaced however they can have an impact on the overall performance. They also decrease the amount of light that goes through, causing drafts. Additionally, if there are deep cracks or chips in your windows, it's unlikely that they will be able to withstand the weight of a replacement upvc window handles unit which will require an entirely new window frame.

4. Higher Utility Bills

It's important to keep energy costs as low as you can. Energy bills that are high not only take a chunk out of your budget, they also put unnecessary pressure on the environment - something we all want to reduce our impact of. One of the most significant reasons for rising energy costs is leaking windows, which not only allow heat to escape your home, but can also cause draughts that require you to make use of more energy to heat your property. Energy efficient windows can help you save money and cut down on your energy bills.

If you see condensation appearing between the panes of your double glazing it's a clear indication that they need to be replaced. It's a sign the seal has broken and air is entering and out of your house and that the insulation is not working as it should be.

If your double glazing is getting misty then it's time to replace the glass. This is a clear indication that the seal is broken and water is trapped between the glass panes. The replacement of your double glazing will stop water from entering your home, prevent heat from leaving and help keep your house warm.

You can cut down on energy consumption and enhance the appearance of your home, and conserve heat by replacing your double-glazed windows with energy efficient windows. This will also increase the value of your home and make it more attractive to potential buyers in the event that you decide to sell. With Category B-rated double glazing, you can expect to save as much as PS115 per year on heating costs, which can quickly pay for misted the cost of the windows you have purchased.

5. Faulty Windows

If you have a double glazed window that has become foggy, misty or hazy, this is an early sign that the seal has failed. It's also a sign that the glass has lost its insulation value and could lead to draughts and condensation. In addition, the gap around the edges of your windows can allow water to enter and damage your wall or plaster. This can also be a serious fire risk.

If the glass in your double glazing is becoming cloudy, you must fix it as quickly as you can, as it's a safety concern. In addition, it may be costing you more money in energy bills than is necessary due to the loss of insulation.

Moisture in the air between your IGU's (insulated glass units) can cause misted windows. The gas inside the glass - usually argon or krypton - assists with insulation, and when the seal fails this gas leaks out, which causes the window to fog up.

Examine your warranty to see if it covers premature seal failure. Certain manufacturers offer a prorated warranty, based on the time of the window. This is something to consider.
