Top Factors to Consider when Choosing Triple Glazed Windows

Triple glazed windows are said to be better than single- or even double-glazed windows. And they are, up to a point. If you live in an area that is prone to harsh winters, then triple glazed windows may definitely be a good choice for you. And if you are concerned about lowering your heating bills, then triple glazed windows may be a viable option as well. But before you run out and choose the next supplier and installer for your triple glazed windows, below are a few factors to consider first.

The right material for the frame

Whilst triple glazed windows offer an intrinsic value due to their spacers and other features, the material for the window frame contributes greatly to their efficiency as well. In this regard, selecting the right frame for your triple glazed windows is important. When it comes to triple glazed windows, you can opt for fibreglass frames which are known for their long lifespan, energy efficiency, and durability.

But the important point to consider is that you need a strong frame for your triple glazed windows, because triple glazed windows are heavier than single-or double-glazed windows. Other than fibreglass, you can choose to have uPVC frames which can also be augmented with steel reinforcements to add to the strength of the window frame.

The sealant strength

Every triple glazed window makes use of sealants in order to seal the unit throughout its perimeter, which then connects or joins it to the spacer’s back. Therefore, it is also essential for you to consider the strength of the sealant to be used for your triple glazed window, as it contributes greatly to the tightness of your window units, preventing air from coming in or escaping. In recent years, innovators have come up with special sealants making use of argon gas, which is said to be better than other regular sealants. But if you would really like to be sure of the sealant to be used for your triple glazed windows, one of your best options is to speak with your window supplier so they can give you the best advice and recommendations based on exactly what you are looking for.

The window’s gas filling

What makes triple glazed windows extra efficient is their gas filling as well. Gas is injected in-between the window’s glass panes, which adds to their insulating properties. There are two basic types of gases which are being used nowadays: argon and krypton. It would be in your best interest to learn more about the difference between the two. To begin with, argon gas is more commonly used, as it is less expensive than krypton gas. Argon gas is also a popular choice because it has a heavier density compared to air, which allows it to provide better thermal insulation and efficiency.

Krypton gas, on the other hand, is more expensive than argon, but it is also known for its better insulating properties. Krypton gas is also more suited to smaller gaps between window panes. However, your ultimate choice in gas filling will depend on your budget, thermal efficiency requirement, and the size of the space between your window panes.

The energy rating of the windows

Energy rating plays a big role in your triple glazed windows as well. Remember that a rating which is closer to zero is better – so if you can get triple glazed windows with a 0.8 rating (such as those offered by Ireland-based window specialists like, then you have made a good choice indeed.
