Double Glazing Or Triple Glazing - Which Of The Two Should You Buy?


When buying new windows from Amber Home Improvements and discussing your requirements with one of our window consultants, you will be asked a series of questions. One of them will be “would you like double or triple glazed windows?”.

Flush Casement Windows External Detail

You may have never given it a second thought and have no idea which will be the best option out of the two. 

Though we wouldn’t push you into buying one over the other, we will happily give you some background information into what double and triple glazing windows each offer to help inform your buying decision. 

Energy efficiency

To uncover what standard of thermal efficiency a double or triple glazed window provides, just find out what it’s U-value is – the lower the U-value, the greater the level of thermal efficiency. 

With a standard UPVC triple glazed window, the U-value will typically be around 1.0 W/m²k. In this example, it will be 40% more thermal efficient than a standard A-rated window. 

Choose a design from our EXTREME range and you will get A+ energy rated windows as standard. 

Soundproofing

Often, triple glazed windows are promoted as being good for soundproofing and keeping external noise out of a house. That is true, to an extent. It all depends on how a set of triple glazed windows are specified. If they’re not specified right, they’ll do very little to curb outdoor noise.

They must have glass panes of different sizes, rather than them all having the same thickness, and the cavities must vary in size too. 

Security

The predominant role of a window is to keep your home well-protected, or at least it should do. No worries on that score with the very latest double and triple windows as they have a multi-point locking mechanism, and robust window frames, making them very difficult to shift when locked.

They are internally glazed too, which prevents the removal of any of the panes from outside of a house. Because a triple glazed window has an extra pane of glass, it provides an extra layer of security.

Price

There is a price difference between double glazed windows and triple glazed windows, with the latter costing a bit more. The big energy savings you will make with triple glazing justifies the extra cost though.

We hope this clarifies things for you, but if you need to know anything more about double or triple glazed windows, contact our team for further advice.
