Triple glazing vs double glazing – should you upgrade?

With the hottest temperature record being broken mixed in with some consistent winter lows, it’s safe to say the UK has experienced some dramatic fluctuations in weather in the past few years. Whether or not your single or double glazed windows need to be replaced, is it worth upgrading to triple glazing? Before we investigate any further, what exactly is triple glazing?

What is triple glazing?

Windows

A triple glazed unit features 3 layers of glass, with the gaps between them being filled with a vacuum or argon gas. These spaces contribute to the window’s ability to prevent heat loss and retain the heat in the home.

Triple glazing has solidified its place as “the norm” in Scandinavian countries to protect homes from cold, harsh winter conditions. Its popularity has been on the rise in the UK for the same reason. The extra pane of glass makes the window more difficult to break and keeps noise out of the home.

Double glazing vs. triple glazing: the showdown

Energy efficiency

While the insulated layer in double glazed windows provides good protection from the elements, the extra layer in triple glazing gives it the edge. Upgrading from single to A-rated double glazing can save an average of £160 per year – these savings can increase further with triple glazing.

At DW Windows, we offer triple glazing that boasts an impressive A+ Window Energy Rating (WER). The average U-value (measuring a window’s ability to prevent heat loss) of 1.2 Wm2K and triple glazed is an impressive 0.8Wm2K.

Winner: Triple glazing

Noise

The insulated layer in windows doesn’t only help energy efficiency, it also helps keep noise pollution out of the home. This reduction in noise is perfect for homes near a busy road or neighbourhood. The additional pane of glass, along with an extra insulated layer, sees triple glazing take this round.

Cost

Various factors contribute to the cost of the windows, including which style of window (such as tilt and turn, casement and sliding sash) you decide on. As more materials are required to manufacture triple glazing windows, they often cost more at the outset than a double glazed equivalent. However, savings on heating bills and the fact that triple glazing can add value to your home still makes triple glazing a worthwhile investment.

Winner: Double glazing

Security

Intruders often consider the windows as the home’s primary weakness. It’s difficult to break a double glazed window but the additional pane of glass makes the triple glazing considerably more difficult to penetrate.

Winner: Triple glazing

However, as with the other points, it’s all down to the quality of the window. Make sure that the windows come with a lengthy guarantee and they are sourced from a trusted and well-reviewed glazing company.
