Question 1

Is it worth having Triple Glazed Windows in my home?

Accepted Answer

A question we are often asked when consulting with our clients is, “Is Triple Glazed worth it?”.  In short, Yes! 

Triple glazed is 2 panes of glass as opposed to 1 or 2. The science behind this is that by having the extra pane, you should increase efficiency, a warmer home thanks to less heat loss and also reduce outside noise. Triple glazed windows have a’ U-Value’ of 0.8. The U-value is the term used to measure the energy efficiency of a window, with old double glazing measuring a U-Value of 3, and more modern Double Glazing having a score of 1.6. So, as you can see, triple glazing is a vast improvement.

Question 2

What is the Difference between Double and Triple Glazed Windows?

Accepted Answer

When weighing up the options when it comes to updating your windows, it is important to understand the main differences between double glazed windows and triple glazed windows. When we fully understand this, we know the full pros and cons of both. 

The only real physical difference in both is that triple glazed windows have an extra pane of glass. So can one pane of glass really make that much of a difference?

Double glazing is less expensive and lighter so easier to install as opposed to Triple glazing that may require structural support around the window frame to with-stand the weight. 

One of the most important areas to consider that we have mentioned in our site is the U-Value (measurement the energy efficiency). The lower the U-value the better, and signifies that the material works better as a insulator and helps keep your home nice and warm. The U-value of Double Glazing is 2.8 where the U-value of Triple Glazing is 0.8.

Question 3

Do you get condensation with Triple Glazing?

Accepted Answer

Triple Glazed windows have a very low U-Value (the importance of which we mention here) due to the use of a low emissivity coating and Argon gas. On a still night, the temperature of the outer glass surface can easily fall below the exterior air temperature or even its dew point temperature. Condensation occurs when the glass temperature falls below the dew point temperature but rest assured this is perfectly normal and a sign that your window is doing its job. This condensation will not evaporate until the glass is heated by wind, sunlight or heat transfer from inside your house. Our triple glazed windows will suffer external condensation, as they are very thermally efficient.
