Greater Efficiency - Greater Cost
Not as common in the UK as some of our European neighbours is triple glazing that's quite prevalent in places like Scandinavia due to the inherent benefits it has over double glazing.
As the name suggests rather than just two panes of glass a third is introduced to further its ability to insulate the home in extremes of cold and reduce solar gain in summer.
As can be seen in the heatmap comparison the benefits are clearly visible and no one can dispute that triple glazing will always outperform double glazed units.
But Is It Worth It?
The question raised is it really worth the additional cost, which can be anything from 30 - 50% higher than conventional double glazed sealed units, and does the UK weather really warrant it? probably not.
It all comes down to the motivation behind it. In a conventional home you couldn't justify the cost based on energy saving alone as the difference between double and triple would be relatively minor.
However, it is known that significant reductions in noise can be had from the third pane. Installing these units into properties near major roads can increase the value of the home and provide a far nicer and quieter environment for the residents.
Alternatively you could specify conventional double glazing with Argon filled sealed units, Argon is heavier than air which will increase energy efficiency and reduce sound transmission through the sealed unit.
If however you're after a Grand Designs style home with large expanses of glass then triple glazing may be a sensible choice over a large surface area.
Triple glazed window suppliers are pretty thin on the ground compared to double glazing and are more often than not fitters of imported units. Here are a few we've found on our travels:
Rawington, specialise in wood/aluminium windows.
Green Steps, supplier of TanumsFonster triple glazed timber framed windows from Sweden.
Velfac - Supply contemporary windows and patio doors with advanced features such as solar control, integral blinds, opaque and noise reducing glass.
