You will notice a considerable difference. It is far more insulative than single or double glazed windows. A brick wall has a U-value of 2.0  W/m²K, a double glazed window has 1.2  W/m²K, and a triple glazed equivalent trumps them all at 0.6  W/m²K. 

You can look forward to great savings on your heating bills, as the interior of your home will retain heat more effectively. 

Bear in mind that triple glazing is more expensive. It’s commonly found in colder areas like Scandinavia where winters are harsher than those in Warminster and the surrounding area.

Switching is worthwhile if your double glazed units are old and underperforming, or if you live in a rural area where temperatures drop sharply during winter nights. However, if you live in a built-up area and your double glazing is new, you won’t see as big a return on your investment.

A specific response to this question is tricky without some data. The area you live in, local weather conditions, and how well maintained your windows are will all contribute to the answer.

For your reassurance, our triple glazed windows carry a 10-year manufacturer’s guarantee. In fact, your units will last decades longer if you regularly clear dirt and debris from the frames. Expect yours to work effectively for 20 years, and even up to 35.

Double glazing keeps heat in using two layers of glass that are filled with argon gas. This gas works to prevent cold transfer from pane to pane. 

The same principle applies with triple glazing, but with a third pane of glass. This extra layer provides more insulation because the units are much thicker.
