Advantages and Disadvantages of Double Glazing

Double Glazing

Are you tired of your boring old single glazed windows throughout your house?

Have you noticed that your rooms are feeling hotter during the summer months and colder during the winter?

Can you hear the neighbors or the cars from the busy road outside your home constantly?

These are some of the reasons why more people are opting to install double glazing in their windows and doors.

But is it really beneficial? We have come up with some pros and cons to help you decide.


1. They help you save on energy bill.

Double glazing uses two panes of glass which helps to significantly reduce the amount of heat that enters or exits your home. As a result your house is cooler during the summer and warmer during the winter, which means you don have to crank up your air conditioner and heater to reach a comfortable temperature resulting in using less electricity.

 2. Double glazing boosts the soundproofing of your home

When double glazing is installed it will result in your windows being thicker which is more effective in reducing the noise that can enter your home. This is a a great for those that might live near a busy freeway, airport, noisy neighbors or neighborhood pets.

3. They Improve your security

Double glazed windows are tougher to break and are difficult for someone to be able to forcefully open from the outside.Having double glazed windows and doors may discourage burglars from trying to break in due to the degree of difficulty of gaining access.

4. Double Glazing can reduce interior fading

Is your expensive leather couch right next to the window that gets the most sun exposure per day? When furniture and decor are exposed to too much heat they can have a tendency to wear and damage more easily. With less heat making its way into your home your furnishings are better protected.

5. Double glazing can help increase property value

Due to all the benefits listed above if you plan to sell a property having double glazing can look more enticing to a buyer if they were originally worried about the properties location or it being in a noisy location.


1. Double glazed windows and doors can trap heat

Although this may be an advantage during winter, but during the summer it can be a problem. A way to combat this is to tint your windows.

2. Double Glazed windows cannot be repaired.

If the seal of your double glazed windows are not air tight then condensation can appear between the panes. And since the windows are already sealed you can’t pull them apart to fix the problem. Instead you have to replace the whole window and end up paying more.

4. They might not be a good match for homes with older architectural styles.

Homes with an older architecture style  may have a mismatched look if you choose to install your typical modern style double glazed windows. There are some specialized double glazing companies that specialize in making double glazed units for older homes or can retro fit into existing windows.

4. Double glazing can cost more initially.

The reason for this is simply because there are two panes of glass instead of just one but if you consider the amount of savings you may get in the long run they may just be a worthwhile investment.
