Is Triple Glazing Better than Double Glazing

Today, triple glazing is not as common in the UK as it appears to be in some European countries, but the popularity of this home-improvement solution is increasing. More homeowners than ever before are beginning to recognise the inherent benefits that triple glazing has over standard single, or double-glazing solutions.

In simple terms, triple glazing refers to the process of using three panes of glass instead of just one or two. The idea is that having an extra pane of glass in place leads to reduced noise and increased energy efficiency. Since we already know that double glazing can offer a significant improvement over single glazing, it only makes sense that jumping further into triple glazing could make an even greater difference.

Understanding Modern Glazing Solutions

As you may already know, the energy efficiency of a standard window in the UK is measured using a “U-value”. The lower that the U-Value is, the more efficient your window becomes. Single glazing generally has a U-value of 5, while modern double glazing has a value of around 1.6, thanks to improved methods of window cavity installation and low-emission coatings.

However, although a rating of 1.6 is obviously a huge improvement over single-glazed windows, a high-quality triple-glazed window can offer a rating of around 0.7 – making them more than twice as efficient as standard double-glazing.

The Unique Benefits of Triple Glazing

Though double glazing can be an exceptional solution for a range of household problems, triple glazing takes home comfort and efficiency to the next level. While double glazing can sometimes be responsible for cold patches within a home as a result of the higher U-value of the windows when compared to doors and walls, triple sealing eradicates this problem. Because the U-value of triple glazing is so low (0.7 compared to the wall U-rating of around 0.3), it minimises problems with heat circulation around the building. This not only eliminates cold spots, but can also reduce the risk of condensation.

Triple glazing can also:

  • Allow you to maintain the same aesthetics as you would achieve with standard single-glazing or double-glazing solutions.
  • Reduce your costly energy bills by improving thermal performance and limiting the amount you need to spend on regular heating and cooling solutions.
  • Minimise noise pollution by providing an effective sound barrier against the outside world – ideal for those who live on busy streets
  • Allow for added security – because triple-glazed windows are more difficult to break, they can offer additional peace of mind to homeowners.

Upgrading your Modern Windows

Although some people still remain unsure about whether triple glazing is better than double glazing, the evidence suggests that it has plenty of unique benefits to offer property owners.

Throughout many countries, triple glazing has already been accepted as the standard for energy efficiency and performance. As home owners around the UK become more conscious about the need to make their properties eco-friendly and efficient, triple glazing could be the best step towards a more sustainable future.
