Triple Glazing vs. Double Glazing

The advantages of Triple Glazing

Triple Glazing Technology

What is Triple Glazing?
As you might already have guessed, Triple Glazing is basically the use of three panes of glass instead of one pane (very early home construction) or two panes (double glazing). Having a third sheet of glass will essentially retain more heat and reduce on external noise.

 

It’s all about Physics…

Infra Red Heat Loss

When it comes to energy efficiency in glazing, we tend to see measurements in ‘U value’ – the lower the better.

One pane of glass will give a U-Value of around 5. Less modern Double Glazing perhaps 2-3, and newer more modern double glazing will have a U-Value of around 1.3-1.6. These recent improvements are down to newer construction techniques, low emission coatings, inert gases being used in the space between the panes, and the use of aluminium dividers.

The Baytree Glass range offers double glazing with a centre pane value of 1.1 to achive WER A rated status. Laminated panes are also an option if noise or safety is a concern.

But lets take a look at Triple Glazing, with U-Values of less than 1.0!

 

How does Triple Glazing stack-up?

So… Double Glazing vs. Triple Glazing – are the improvements worthwhile?

Well, the latest in triple glazing technology have typical U-values of around 0.8 – a massive improvement upon even the best that double glazing has to offer! These new technologies are also getting closer to the magical U-Value of 0.3, which is the level of performance a typical cavity or insulated brick wall can offer.

Is it all about the glass?
In short, no. Having three sheets of glass is only part of the magic when getting U-Values down. Just as important is a modern, well designed frame… as without this, you will experience a large amount of heat loss directly through the surround.

So, it’s all about heat retention?
Again, no. There are some other really great bonuses to having Triple Glazing installed;

Keeping the damp down…
Not only will you get much better heat retention, but you’ll also benefit from a massive improvement when it comes to condensation. In Single and even Double Glazed homes, the difference in temperature between the glass and the rest of the building can lead to condensation forming. Triple Glazing however, reduces the difference in U-Value between the windows and the rest of your home, meaning less moisture condensing on the inner pane.

Chilly spots?
Even with Double Glazing, you can still get cold spots in your home, due to the difference in temperature between the inner pane of glass and the rest of the building. With Triple Glazing, the difference is minimised, thus improving on this.

Noisy neighbours?
You’ll love the fact that Triple Glazing cuts down yet again on outside noise – even when compared with other modern glazing solutions. Typically, you’ll benefit from less noise than with Double Glazing, but at Baytree we can offer the sound and secure glass range that is avaliable in a double glazed unit also.
