Double-Glazed Windows

Double glazed windows are windows that have two panes of glass. These windows are characterized by the inclusion of an inner pane of glass, which is insulated by an intermediate space filled with argon or krypton gas.

The gap in between both panes of glass is sealed to stop leakage in the event of breakage.

Argon gas also has the added benefit of reducing noise transmission, which is why it is often used in double glazed windows.

Double glazed windows are a common sight in the US, UK and other countries.

 They are popular because they help to keep your home cool in summer and warm during winter months, as well as reducing noise pollution from outside.

The name “double-glazing” comes from the fact that there are two panes of glass between you and the outdoors – one on the inside of your window frame, and one on its outside surface.

This double pane helps to reduce heat loss by trapping air near the window’s insulating surfaces.

The average lifespan of double glazing is believed to be between 20 and 35 years, depending on the supplier and fitting.

Double-glazed windows are elegant, methodical, strong, durable, insulated, secure, easy to maintain and are less maintenance turn.

Less maintenance will ultimately save you money over the long term.

Double-glazed windows are a great way to keep your home more comfortable in the winter.

They reduce drafts, help with insulation, and can be an effective noise barrier. However, there are some disadvantages of double-glazed windows that you should consider before installing them.

 Double glazing is expensive because it requires two panes of glass to be installed inside the window frame instead of just one pane like traditional single glazing does.

 It also increases the weight of your window which may cause problems for older homes or those with structural weakness.

Finally, if you have sliding doors on the east side of your house then double-glazed will block out sunlight during morning hours when people typically wake up and get ready for work or school!

Double Glazing Vs Single Glazing Cost

Generally, the cost of double glazing is around 30-40% more than that of single-pane windows. The price difference is due to the fact that double-glazed windows require additional materials.

The cost differences between double glazing and single glazing can be looked at in terms of the energy savings provided by double glazed windows.

Although they are more expensive than single glazed windows, even the most basic double-glazed window may save you up to 20% or more on energy use depending on your climate.

 When you multiply those savings by the 20 or more years your windows will endure, the difference is astounding.

 uPVC windows with double glazing are difficult to match in terms of overall durability and energy efficiency.

Double glazed or two pane windows can cost as little as $200 per square metre or as much as $1,000 per square meter on average.

Benefits of Replacing Single Glazing with Double Glazing

1. Reducing noise pollution:

Double glazing reduces noise significantly, by up to 37 decibels, simply by filling the space between the two panes of glass with gas that is compressed by an inert gas.

2.  Increased insulation:

Double glazing produces a tighter seal around the window. This means that the glass is better at keeping out the undesirable air that is present in your home.

In effect, it acts as an air barrier, which reduces heat loss by up to 30%.

3. Improved aesthetics:

Double glazing has a firmer feel and better design with multi-pane windows, which have insulated glass that comes in various styles to match your home’s decor.

4. Longer window life:

The two pieces of glass in a double-glazed window are designed to be able to withstand the elements much better than a single pane can.

They are also better at keeping out the undesirable moisture and heat that is present in the air.

This is important because exposure to damp and heat can lead to condensation and premature aging of the window.

 Double Glazed Windows Pros

1. Reduced Noise Pollution

Single-glazed windows are known for giving inadequate sound insulation.

Noises from the neighborhood, cars, and children playing may all be heard. Double glazed windows provide additional noise pollution protection. Particularly efficient systems can reduce noise levels by up to 35 decibels.

Single-pane windows also have a distracting rattling on windy days, especially as they age. This problem is solved by the stronger construction of double glazing.

These considerations are especially essential if you are one of the growing number of people who work from home.

 Instead of being continuously distracted by what’s happening on outside, this will help you to concentrate better.

2.  Good thermal insulation:

Double glazing employs two panes of glass, which greatly reduces the amount of heat that enters and exits your home.

They assist you in saving money on your energy cost.

 As a consequence, your house is cooler in the summer and warmer in the winter, which means you don’t have to turn up your air conditioner or heater to attain a comfortable temperature, which saves you money on energy.

3. Saving Energy:

Double-glazed windows provide additional insulation and thermal barriers, which reduces the amount of heat loss, and the use of your heating or cooling system.

Due to their low thermal conductivity (around 0.1 BTU vs 0.5 for single pane windows), double-glazed windows also help you to save money on energy bills as they can reduce your heating costs by up to 30%.

4. Window Frames:

Double-glazed windows should have a stronger window frame as it should be able to hold up to the increased weight of these windows.

Double-glazed windows are heavier because of the extra layer of glass.

Double-glazed window frames should also have a gas filling between the two glazing sheets, which helps to block sound from passing through.

In contrast, single-pane windows have an insulating fill that only works in one direction since it does not fill the space between both panes of glass.

5. Improved Aesthetics

Double-glazed windows have a better appearance as they have a firmer feel and better design.

This includes multi-pane windows, which have insulated glass that comes in various styles to match your home’s decor.

6. Longer Window Life:

The two pieces of glass in a double-glazing window are designed to be able to withstand the elements much better than a single pane can.

They are better at keeping out the undesirable moisture and heat that is present in the air.

This is important because exposure to damp and heat can lead to condensation and premature aging of the window.

7.  Improved security;

Double-glazed windows are more difficult to break and more difficult to force open from the outside.

Due of the difficulty of obtaining entry, having double glazed windows and doors may deter criminals from attempting to break in.

8. Help increase property value:

A house with double glazed windows and doors is much more appealing. Double glazed windows are considered an attractive feature for consumers who are looking to purchase new housing.

What are the main drawbacks of double-glazed windows?

A double-glazing window can be made of two or three panes of glass, with each pane separated by a gas space and an inner and outer layer of pane glass.

This additional insulation is what makes double glazing more energy efficient than single paned windows.

There are very few disadvantages to double-glazed windows, since they are the most efficient form of glass panes that provides thermal insulation for your home.

1. Installation:

Double-glazed windows are usually more expensive to install compared with single-glazed ones, but they are also more durable and will last longer than single pane windows.

 The main drawback is that they take longer to install. You must have at least two days available for you to complete the installation of double glazing.

2. Double Glazed windows cannot be repaired:

Due to their complex structure and the necessity to use special tools during repairs, it is nearly impossible to repair double glazed windows.

It is therefore recommended that you use high-quality windows that will last for a long time and will offer maximum protection and energy efficiency.

3. Double glazed windows are heavier:

Double-glazed windows weigh more than single glazed windows, so they must be mounted firmly in the frame. This could prove difficult as they are heavier, and if the frame is not strong enough, it could shift.

Many frames do not have enough clearance for extra glass, so it can shake or even fall out of the frame and break. If this happens, you will be faced with a problem: 

4. Exterior double glazing:

Double-glazed windows work well for homes with healthy outside environments; however, they may make it more difficult to maintain your exterior because moisture will escape through them easily. This may also cause your window frames to rot if they are not properly sealed.
