Double Glazed vs Triple Glazed Windows

Are double glazed or triple glazed windows best? The answer depends on exactly what you'd like to do with your home. Either way, though, if you have windows that are getting old, or use cheap materials, it could be time to replace them. Older windows lose a lot of heat, as they have thin designs that don't insulate your living space. In some cases, you can even lose up to 10% of your home's energy due to their outdated designs.

However, you may not have to replace the window entirely. If you want to enhance your living space without spending too much, then you can still make a significant difference by replacing the glazing in your home. You'll have multiple options for the new glass, but you'll have two main choices of glazing. Firstly, there's a double glazing option, which has become the standard for modern homes. However, you could also choose triple glazing for your new window.

The difference between the two, on the surface, is simple. Double glazing uses two panes of glass while triple glazing adds a third. That means that you would expect triple glazing to be the better option. It is in some departments, improving your home's insulation, and also protecting you from intruders. But triple glazing does have some drawbacks, such as less natural light and increased weight, potentially putting a strain on the window frame.

Because of this, the choice between double glazed and triple glazed windows isn't as clear-cut as you think. Also, triple glazing costs around 30-40% more to install per window, meaning you'll have to spend a lot more for an extra pane. By using Compare Companies, though, you can reduce the price of installing both, meaning you'll make a truly worthwhile investment.

Double Glazed vs Triple Glazed Windows: Design

So how does the design of the glass affect your home? Double glazing works by putting two panes of glass inside your window frame. Because of this, there's a small space where air can become trapped. That means that you can create a thermal barrier for your home, which will stop cold air from outside entering. Not only that, but it'll also prevent your home's natural warmth from escaping, making your home much more comfortable.

Modern double glazing is also clear and bright, letting in vast amounts of natural sunshine. As a result, it'll lift the look and feel of your whole living space, making it seem more open and more welcoming. Also, double glazing is lightweight in its design, making it ideal for fitting into frames which aren't as durable as advanced options. It won't put as much strain on the existing structure, meaning your old windows could last a little longer.

Triple glazing can save more energy, but it comes at a price. Firstly, you won't let as much natural light through, which means it may not be as ideal for conservatories or sunrooms. Also, the extra weight can put more of a strain on an old frame. Because of this, triple glazing is more beneficial when you fit it into an entirely new window. In any case, however, both double glazed and triple glazed windows have designs that can revitalise your living space.

Double Glazed vs Triple Glazed Windows: Thermal Efficiency

The first way in which both double glazed and triple glazed windows can impact your home is in the way it channels energy. With an old window, you can lose up to 10% of your home's natural warmth. That makes an enormous difference, and it could mean that you have to rely on your central heating to stay comfortable. With double or triple glazing, though, you can generate warmth for your home more naturally.

Double glazing is air and water-tight, and you'll be able to get a made-to-measure option that fits your window perfectly. That means draughts won't be able to develop, and cold air will have a much harder time getting through. However, double glazing can help in the summer too. When your home starts to feel stuffy, you can open the window to ventilate your home. Double glazing is less weighty, meaning you could get a smoother opening for longer.

With triple glazing, though, you'll save much more energy. With three panes of glass, you could almost replace your central heating, let alone reduce your energy usage. When you compare them to double glazed windows, triple glazed windows can save up to 50% more energy. For a 30-40% price premium, that can make them a more worthwhile investment. You'll be able to save more money on your household bills every day, and you'll decrease your carbon footprint as well!

Double Glazed vs Triple Glazed Windows: Security

It's vital to make sure your home keeps you safe. That's why installing both double glazed, and triple glazed windows can be so helpful. In your old windows, you may have a timber frame and single-glazed glass which is beginning to chip and crack. Both of these materials can start to wear down over time, making the whole window more fragile. That could lead to intruders targeting the window, seeing it as an easy way into your home.

You can stop them getting in with ease, however. A new double glazed window will have internal security features that are a nightmare for any burglar. You'll get a multi-point locking system which fastens the glazing to the frame, stopping anybody from separating it. Also, double glazing is much more durable than a single layer of glass. Because of this, you won't have to worry about it breaking, chipping or cracking.

But, for absolute peace of mind, triple glazed windows are a step up. Triple glazing is far more robust, improving the overall strength of your window. Not only that but if you fit triple glazing with a brand-new frame as well, you can choose from even more advanced materials. An aluminium frame, for example, is almost bulletproof, and it'll protect the hardware inside from rust. That means you'll always be able to rely on triple glazed windows to protect what matters most.

Double Glazed vs Triple Glazed Windows: Weather Protection

Another issue with old windows is that they struggle to deal with poor weather conditions. Single glazed glass, over time, can start to weaken in adverse weather. As a result, water can begin to seep through, and wind will be able to enter your living space more quickly. Your window frame is arguably even more susceptible to these issues, as well. If you have a wooden window, then water can expand cracks in the timber and turn your home damp and cold.

With double glazing, you can make your windows air and water-tight. Also, the glazing will be made-to-measure, reducing gaps that water and wind could enter your home through. You'll feel a more significant impact installing new glazing with a brand-new frame, however. Both uPVC and aluminium are weatherproof designs that won't lose their performance even in the worst conditions, and you won't have to clean them as often either.

Triple glazing will offer more protection for your home, but not a massive amount. The main benefit is that you won't feel as much of the weather outside, making your home a more comfortable place throughout the year. That means that it isn't necessary to get triple glazing to make your home weatherproof, although it will provide more performance in other areas. Both double glazed and triple glazed windows can make the rain go away.

Double Glazed vs Triple Glazed Windows: Maintenance

One of the main benefits of replacing your windows is that you'll invest in your home's future. Right now, you may be worried about having to repair your old windows. Over time, this will only become more common, as the whole design becomes weaker and more fragile. The cost of repairing these windows can accumulate quickly, and it can take up a lot of your precious free time too. So, why keep maintaining your old window when you could get a new one?

Double glazed and triple glazed windows are much easier to look after. The glass is less prone to cracking, but also condensation as well. That's because there's less difference between the temperatures on either side, meaning the conditions aren't as conducive for condensation to develop. As a result, the windows won't mist up, saving you time on cleaning them and improving the lighting in your home.

Both of these windows also don't need repainting. If you have a wooden window, then you'll know how time-consuming it can be to keep revarnishing your windows. Instead, you can get new glazing along with a frame that retains its colour. You can even style it with bold RAL colours or authentic finishes that won't fade for decades. New double glazed and triple glazed windows can perform for that long without needing repairs, too, making them a long-lasting option for your home.

Double Glazed vs Triple Glazed Windows: Lifespan

So, how long do both double glazed and triple glazed windows last? There is a difference, but it depends on the precise window you choose. In most cases, triple glazing can outlast double glazing on its own though. As it has an extra pane of glass in its design, it should take longer for conditions to affect the glazing, and it'll be less likely to mist up, break, or scratch. That means that you can save more money, and for more time than you could with double glazing too.

But that doesn't mean double glazing isn't a long-lasting option as well. Thanks to its weatherproof design, multi-point locking systems, and a range of protective foils, you can make double glazing last for decades. Not only that, but you can improve its lifespan when you fit it alongside a new aluminium frame. Aluminium is a precious metal with outstanding strength, and the material can perform at its peak for close to half a century.

Getting a brand-new frame can make all the difference to the lifespan of your windows. Modern designs are just so much more durable than their predecessors, meaning there's no need to put up with your old windows. Instead, you can enhance your home with a stunning new design that incorporates either double or triple glazing. You can also choose from options that have wide apertures and unique opening systems to transform your living space yet further.

Double Glazed vs Triple Glazed Windows: Cost

Double glazed windows can cost as little as £150 to add into your home. Not only that, but that comes with a brand-new frame and a full fitting from a superb local installer. If you only want to replace the glass in a window, though, you could spend even less. New double glazing could only cost around £50 to add in each window, depending on the size and style of the design. Triple glazing, in both cases, can add around a third to the cost.

However, the price can rise quickly depending on the design you choose. If you want a new window entirely, for example, then you could find that you can pay around £500 or more for each one. That's if you choose a bold opening, such as the tilt and turn or sliding sash options, with either double or triple glazing. Although replacing the glass alone can cost a lot less, you won't feel as significant of an effect, and a brand-new window can save you more money on household bills as well.
