If you are renovating your home, there are many things to think about. When you set aside time, money, and energy to renovate your house, you want to do it right. The moment it comes to replacing the windows, you will probably start asking which type of window is best to choose to replace your single glazed windows.

One thing you should know is that both double and triple glazed windows have their pros and cons. Depending on your needs, budget, and preferences, you will find one of them a better fit for you. Here are some more details about the advantages and disadvantages of double and triple glazed windows.

  1. Insulating properties

A vital property of a window is how well it insulates the home. When you’re renovating your house, you want to make sure the windows are not allowing the heat to leave the house. Both double and triple glazed windows have good insulating properties, but triple-glazed ones are on a bit higher level.

When windows are triple-glazed, that means they have three panes of glass built into the frame. In between those panes is a gas denser than air (usually argon), which provides excellent insulation. Double-glazed windows have only two panes and therefore lack a layer of gas.

That is why you should choose windows with triple glazing if you live in a colder area, so insulating properties are crucial for you. Also, if you’re taking care of energy efficiency and want to reduce energy costs, you should consider windows that provide better insulation. In recent years, the emphasis has been on energy conservation, with good reason. A lot is happening with the Earth, so we should all try to make our contribution to make it a better place to live. Even small things like choosing the windows with an extra layer are significant enough. Of course, if these criteria aren’t that significant to you, then double-glazed windows will do the work, too. It is all about your preferences.

At, you can find many different double-glazed windows you might like. You can always to their professionals and ask them to help you pick the best one for you. They will also measure your windows and install them as quickly as possible. With them, you get the full service and a great, easy experience with window replacement.

  1. Costs

When it comes to costs, there are two sides. The initial costs are much lower in the case of double-glazed windows. But in the long run, you will save more money by purchasing triple-glazed ones. As we mentioned, windows with triple glazing have better heat-insulating properties.

Over time, your gas bill won’t be as large as it would be with double-glazed windows. But keep in mind that not everything is black and white. Good insulating properties won’t be crucial if your house is old and loses the heat in some other ways. Then it won’t matter that you installed triple-glazed windows, your energy bills won’t be significantly lower and it doesn’t make sense to spend more money on them. Another thing about triple-glazed windows is their amazing lifespan.

They have great durability and can last up to thirty years, which is not the case with double-glazed ones. So yes, you’ll be paying less in the beginning if you choose double-glazed windows, but you’ll have to replace them much sooner, which means you’ll pay more for them in the long run. The final choice will depend on your budget. If you have a good starting point, we recommend going with triple-glazed windows, but if you can’t afford them right now, then double-glazed ones will be good enough. You’ll be giving more money over time, but if that suits you better, then why not.

  1. Noise reduction

For everyone living in a city, surrounded by a lot of traffic, noise reduction can be more than helpful. Also, you may live in a small suburb, but you have loud neighbors who wake you up every morning or there are constructions near your house. On the other side, if you play an instrument or you have many loud family members, getting windows that have good sound insulation is a good choice.

Triple-glazed windows have better noise reduction properties, compared to double-glazed ones. We already said they have more panes in the frame and more layers of gas. All of that ensures excellent sound insulation. However, keep in your mind that various factors can affect the quality and level of noise reduction. The thickness of the glass is vital for sound insulation and choosing a window that has various thickness panes allow you to remove sounds of different frequencies.

The best noise reduction is achieved when the difference between panes thickness is 33% or more. It does not matter the order in which the panes are arranged. The distance between the panes in the frame is also significant for sound insulation. The last thing you should keep in mind is that you should avoid trickle ventilators on your windows.

Otherwise, they will suppress the sound reduction you want to achieve. If you’re not sure what type of window you should choose, consider consulting with a professional and discussing the main reasons why you need good sound insulation. They can help you understand your options and get to the conclusion you’ll be satisfied with.


When renovating a house, you need to take care of plenty of things. Purchasing good windows is one of them. At one point, you will probably start to wonder whether double or triple glazed windows are a better option for you. There is no right or wrong answer to this question.

Depending on your budget and overall needs, you will probably find that one of those two types work better for you. In general, triple-glazed windows are thicker and provide better heat insulation and noise reduction. Double-glazed ones are initially cheaper, so if you’re on a budget, you could find them a better choice. Be sure to do your research and figure out what windows are more suitable for you and your home.
