When moving home or thinking of upgrading your windows from single glazing, you might wonder whether you should choose double or triple glazing.

It’s not just about the fact that double glazing includes two panes of glass, whereas triple glazing has three.

There are so many more benefits/disadvantages of both that you should consider before you choose either.

You should also think about the cost, how energy efficient they are and how they insulate your house.

In order to help you make your decision, this article will show you what each of them is, how they can benefit your home, how efficient they are, and the cost of each of them.

But first, what are triple glazed windows?

To put it simply, triple glazed windows are modern energy-saving windows.

They are insulated in order to keep heat in and noise out.

The cavity between each of the panes is usually filled with either krypton, xenon or argon.

This creates a seal that reduces the draft and keeps the heat within the house.

So, what are some advantages and disadvantages that come with having triple glazed windows installed?

Firstly, the pros:

• They offer great sound insulation – better than double glazing!
• High durability and lifespan (triple glazing can last around 30 years!)
• More secure against break-ins, due to the added layer of glazing
• Produces a low U-value (More about ‘U-values’)
• They are extremely energy efficient and can help bring down the amount you spend on your energy bill.

Secondly, the cons:

• Installation can be more expensive than double glazing.
• A lot heavier than single or double glazing, due to the added layer.
• It may not be necessary for the UK climate.

Secondly, what is double glazing?

A double-glazed window is made up of two panes of glass. These panes provide a barrier between the house and the outside.

The gap between the panes provides a good level of insulation, a feature that is great for those colder months.

Double glazing is found on most modern houses and is generally, very reasonably priced.

People that upgrade from single glazing to double glazing will start to notice the impact on their electricity bills as soon as they are installed. 

Here are some pros and cons of installing double glazing:

Firstly, the pros:

• It can be cheaper than triple glazing (typical price estimates)
• They can reduce heat loss by up to 100%.
• They are the most popular choice for households across the country.
• Very good at keeping noise out of your home, making them ideal for homes situated in loud, busy, or built-up areas

Secondly, the cons:

• They are less energy-efficient than single or triple glazing.
• Double glazing is not as secure as triple glazing. In which the third pane adds an extra layer of strength.
• Unfortunately they aren’t as long-lasting as triple glazing.

Which Deals Better With Condensation?

This probably won’t come as a surprise, but triple-glazed windows tend to deal with condensation better.

This is due to the fact that it has three panes – therefore will allow for less of a difference between the temperature inside and outside the house.

If you have double-glazed windows and notice a lot of condensation between the panes, it might be a good idea to upgrade to triple glazing.

Condensation can cause problems to the window frames and excessive moisture. Ideally, it is an issue that should be fixed as soon as possible.

If you don’t have any issues with your current double glazing, then it might not be worth changing them all to triple glazed windows.

Are Double Or Triple Glazed Windows More Energy Efficient?

When you are working out which type of window is better in terms of thermal transmittance, it’s important to look for the ‘U-value’ measurement.

This is an industry-standard that is often used to compare a window’s energy performance. If the U-value is low, the window is more energy efficient.

It’s clear that as double glazing has two panes rather than three, it won’t retain as much heat.

Is it really necessary, however, for those living in the UK?

The answer to this is probably no, it isn’t necessary. The difference in your heating bill won’t be a lot, whether you have double or triple glazing.

However, you shouldn’t only consider the amount of energy transfer that you lose (or gain) through your windows!

It is also thinking about the solar gain that comes with both double and triple glazing.

Increasing the temperatures inside the room, if it’s a particularly hot day and you want your house to warm up accordingly, triple glazing will allow for less of this heat to seep through in comparison to double glazing.

This means that you won’t benefit from the same amount of natural warmth with triple glazing as you would with double glazing.

How Much Does Double Glazing Cost?

This, of course, will depend on the style and size of the windows (as well as how many windows you need instead) that you want in your home.

When it comes to windows, there are different options for you to consider. Each option has its benefits, and there are plenty of things to take into account. When choosing which windows you want, think about which are going to be best for your property.

One of these things is the cost of triple glazing. We are going to be looking into the different options, and how they impact triple glazing cost in more detail down below.

If you are interested in finding out the different window options available for you to choose from, and how much they cost, then keep reading!

What Is Triple Glazing

Triple glazing is a type of window that is made up of three panes of glass, instead of one or two. They provide various benefits to the building, such as protection from noise.

Between each pane of glass, there is usually gas such as argon or xenon. This works together with the extra pane to keep out a lot of the outside world.

This is the only real difference between triple glazing and the other options that are available on the market.

Different Window Options

Other than triple glazing, you can look into double glazing or a single pane window. Double glazing, as suggested in the name, uses two panels of glass to create the window.

They were initially designed to exclude heat from the property. Before the invention of triple glazing, they were the best option on the market.

Alternatively, there is a single glazed window option, which only uses one pane of glass. As you can imagine, this is not as effective as the other choices when it comes to keeping heat inside the home and blocking out noise.

Each option does come with a price difference. This is something that we will be looking into a little further down in the article. We aim to help you find out the cost of triple glazing.

Benefits Of Triple Glazing

As there are more panes of glass used in triple glazing. It is more effective at certain things. One of these is keeping noise out of the property, all hours of the day.

The thickness of triple glazing is a huge selling point, especially to those who live in noisy areas. By having a third pane of window glass, there is an added layer in place. This gives an extra blanket of protection against the outside noise.

Another benefit is that it provides the property with more security as triple glazing is a lot stronger than single and double glazing.

This means that if anyone does try to break into the property through the window. They are going to have a much more difficult time. If you have invested in getting triple glazed windows rather than one of the other options.

Or, you might be interested in the fact that it will make the property warmer as it stops heat loss more effectively than the other two.

This will, in turn, help to lower your gas or electric bill as there will be less heat escaping throughout the day which means that you are not going to need your heating on as often.

The trapped heat will also help to make the property cosier which is going to be something important if you are trying to create a homely environment.

Cons Of Triple Glazing

However, it is not all sunny days, and we mean this literally because triple glazing can impact the amount of light that enters your home.

The thickness of the glass panes makes it harder for the sun rays to reach inside your property. Therefore, the natural light is significantly less than with double or single glazing.

This is the only con of triple glazing other than the price, so make sure that you need the upgrade or it is something that you think is going to be useful for your home. Don’t forget to consider this as if natural light is essential to you. It could be a deal-breaker.

Average Cost Of Triple Glazing

This, yet again depends on how many you want to be installed and the quality of them.

Something that you do need to be aware of is that triple glazing cost is quite a bit more expensive than single and double glazing, but this is for a good reason. With the bonuses that come with the extra pane, you would expect to pay a little more for this.

Triple glazed windows also require more materials to make and need a specialised manufacturing process – that many window glaziers might not offer.

It is hard to give you an accurate idea of how much triple glazing is going to cost you precisely because you are going to need a quote from a Double Glazing Installer.

But this doesn’t mean that we can’t give you a rough idea. It is all going to depend on what kind of property you are in, how many windows there are and a few other factors to how much you can expect to pay for this service.

When you compare them in terms of their energy efficiency, the difference in the money you save with heating is minimal.

Therefore, you need to consider whether triple glazing is truly worth it.

So, if you are looking to replace around four windows in your two-bedroom flat, you are going to be looking at roughly £2000.

What to do Next

Now, as we said above, please do not take the figures that we are providing you with as gospel because some companies may charge more or less depending on what they have set their rate at.

If you live in a two-bedroom terrace which will usually have roughly five or six windows, you are going to be looking at between £2500-£3000. Do you see the pattern here?

Typically, you are going to be looking at paying around £500 per window that you want triple glazing on, so you should time this by the number of windows in the home for a rough estimate.

Do be careful, though when you are trying to work this out because the price per window usually decreases if you have more windows. So, if you have twelve windows in your three-bedroom house, you can expect to pay around £6,000.

If you decide to replace all your windows at the same time, it could end up costing you a lot less than it would replace them in small clusters.

The Difference In Price

But, what is the difference in price when it comes to single, double, and triple glazed windows? Well, as we said above, you can expect to pay around £500 per triple glazed window in your home, depending on the number of windows that need replacing.

If we look at double-glazed windows, you can expect to pay around £350 per window or maybe just under. So, it is quite a big difference, but this is no surprise when you think about the benefits and how just how much of a difference you will see when you upgrade from single or double-glazed to triple.

Finally, Is Triple Glazing Really Worth It?

As mentioned throughout this article, triple glazing is significantly more than double glazing – so is it really worth the hefty investment?

You can easily get all the benefits from triple glazing with double glazing if you update them.

There are double glazing windows options on the market that are modern, have A+ energy efficient ratings and offer excellent U-values.

Yes, they might not hold just as much heat as triple glazing does, but does that extra pane of glass really make all the difference?

This, of course, is a decision that has to be made by you.

If you don’t want to spend more for a little less heat loss, it probably isn’t worth it.

You should also consider the fact that triple glazed windows will add an extra level of security to your home, making it harder for vandals to break into.

This is sure to give you a bit more peace of mind when you are leaving your property to either go to work, out to the shops or away on holiday.

It will also depend on what windows you want to upgrade throughout your home. If it’s all of them, the cost will be more substantial.

But, if you only want to upgrade the windows downstairs in your property, it might be worth it in the long run.


Before making the decision whether you will choose double vs triple glazing.

It’s important that you do thorough research, get quotes for each and think about what you want to get out of them.

By deciding which type is more appropriate for your needs, you can discover the types of glass that is available.

As well as the styles and what impact they will have on your home.

It’s a big investment – no matter which one you choose, so it’s important to think carefully first before taking the plunge.

Windows are a big part of your home and could be the difference between a large electricity bill and a small one – as well as making it more appealing to potential buyers when you go to sell your house in the future.
