Triple Glazing

To your new windows or can be fitted to your existing PVC-u windows

What is triple glazing?

If you’re familiar with double glazing, then you’ll be pretty comfortable with its not-so-distant cousin, triple glazing. Triple glazing takes double glazing that extra step further, by simply adding another pane of glass to the window. This third pane of glass acts as an extra layer of insulation to your house, keeping you cosy during those bitter winter months.

How does it work?

Triple glazing is a bit like layering up before you brave the winter chill – except the insulation isn’t just coming from the extra layers. There is also a small gap between each of the three panes of glass, which is either filled with air or an insulating gas, such as argon. Argon is much heavier than air, which means it acts as a stronger barrier against any escaping heat.

This extra third layer also comes with other benefits, such as blocking out any outside noise, providing greater security, and adding value to your home.

So, is triple glazing worth it?

The image below shows a thermographic survey, comparing old double glazing (left) to new triple glazing (right). The red spots on this image show you where the heat is leaving the house, which should tell you everything you need to know about whether triple glazing is really worth it.

We offer Triple Glazing to your new windows or to your existing PVC-u windows.

Thermal performance

When it comes to thermal performance, triple glazing wins hands down.

The energy efficiency of a window is measured by its U-value – the lower the number, the better. Double glazed windows are typically given a U-value of 1.6 for new ones or  whereas triple glazed is rated an impressive 0.8 in new frames or 0.98 to existing frames.
