Why You Should Consider Triple-glazed Windows

Large modern windowsInstalling triple glazing not only helps to make your house as energy-efficient as possible but it also comes with additional benefits, including improved security.

These days, not many people would install single glazing. In fact, it is not allowed by today’s Building Regulations, except for listed properties.

However, will there come a time when triple glazing is the norm and double glazing is considered to be insufficient?

For many homeowners, energy efficiency is high on their priority lists so they visit a supplier like Bill Butters Windows. There are also some other persuasive arguments that can be made for triple glazing. So it is worth it to invest in this high-performance option?

What Are the Differences Between Triple and Double Glazing, and Why Is It Necessary?

New builds frequently feature large amounts of glazing – roof lights, sliding doors, picture windows. However, all of this glass has energy efficiency implications, since heat can pass through glazing much easier than through insulated walls.

With stricter Building Regulations being put into place, glazing companies have needed to rise to this challenge to create products that perform better. Triple glazing is one of the solutions that come from with improved insulation, where there are two air pockets rather than just one.

A Low-energy House

In the colder climates of northern Europe, triple glazing has become the standard. Also, it is considered to be essential in ultralow-energy, modern, new build homes where a combination of features is used to make it as efficient as possible, ranging from getting rid of micro-gaps in fabric to high insulation levels to ensure that the home is airtight.

Triple-glazed Window Panes

Triple glazing is an efficient option that provides greater insulation levels.

Triple glazing is well above the standards of Building Regulations for energy efficiency as long as the products are properly installed. There isn’t any point in installing super-insulated windows if there are any gaps surrounding them where air can leak out.


The three glass panes are not the only thing that improves the efficiency of a unit. Other features (which are available in both triple- and double-glazed products) that help to give the performance a boost include argon or another type of inert gas between the panes of gas that is less conductive than air (which makes it more insulating).

Insulation can also be improved by low E glass. One of the inward-facing panes of the product has an invisible metal oxide coating that reflects heat back into that room.

Also, look for a product that has “warm edge” spacer bars that sit in between the panes of glass. They are made out of plastic composite and conduct less heat compared to aluminum which has been used traditionally for that component.

Noise and security benefits

Since triple glazing is very hard to break, it can also work as a break-in or vandalism deterrent.

In terms of noise reduction, there is a minor benefit. However, if your top priority is acoustics, then other options are a lot more efficient, like units with a bigger gap between the laminated glass and panes or secondary glazing.

Is It Worth the Investment?

In certain circumstances the answer is definitely yes. Triple glazing is much more likely to benefit those living in cold climates. It can make a big difference to your comfort compared to living in an area with milder weather.

One of the more energy-intense manufacturing methods is used to produce glass. So you need to weigh whether it is worth it to have an extra pane of glass for the added comfort it will provide, instead of just thinking about it strictly from the standpoint of lowering your bills and saving the planet.
