There is certainly a case to be produced insulating your house along with possible. However is it beneficial to upgrade to Triple glazing?
Here we take a peek at the Pros & Cons of Double Glazing Vs Triple Glazed Windows?
Double Glazed Windows– the essentials
Double Glazing Vs Triple GlazingFor those of you who do not know, the principle involved in double glazing is to produce an area in between the outer and the inner surfaces of the window. The gap, often filled with a gas, reduces convection of cold and heat whilst also functioning as a sound buffer.
The size of the space, in modern double glazed windows, is rather important. Too small and it becomes less effective, too big and the air in the space will flow. and reduce the effectiveness.
Space sizes range from 4mm to 20mm. If you include the density of the glass (2 x 4 mm panes) then the actual density of a double glazed unit runs from 12mm to 28mm.
If you think of a double glazed window as a sandwich, then the glass is the bread and the gap is the filling. The panes are held apart from each other by spacer bars around the edge.
The space is normally filled with dehydrated air, but that can be replaced with a gas (such as Argon) to more improve insulation. Argon gas systems cost about 5% more per window, however can enhance the effectiveness by as much as 30%.
More insulation can be gained by using metal oxide finishings on the glass– frequently described as “Low-e” glass.
Triple Glazed Windows– the basics.
What you get with triple glazed windows is all of the above, however with a 3rd pane of glass. The 3rd pane noticeably improves sound insulation and thermal insulation, since now you have 2 air gaps. If you integrate that with Low-e glass, Argon gas and warm edge spacers, you have a very energy efficient window.
To use somebody else’s figures, when a test was worked on the within a window in a space that was heated up to 21 degrees, and it was suitably cold outside. A single glazed window offered a reading of 1 degree.
It’s quickly demonstrating a big difference from single to double glazing, however not such a huge gain with double glazing Vs Triple Glazed Windows.
Benefits of Triple Glazing
The obvious thing to state is that triple glazing is much better than double glazing for heat performance.
- Triple glazing offers improved noise decrease.
- Triple glazing is much better at removing hot & cold areas in the house.
- Triple Glazing has better condensation control.
- Triple panes of glass make the window more safe
Advantages of Double Glazing
- Double glazed windows are cheaper to purchase.
- The frames are thinner and less bulky.
- Double Glazed window systems weigh less and don’t put a lot strain on the hinges & corner joints.
- if a repair is required, then the cost of that repair can be greater (replacing all the window seals).
- Triple glazed windows with the middle pane made from float glass can have an issue with the middle pane breaking due to temperature differences from the outdoors & within– you should use toughened glass which is more expensive.
Summary– So which is better for your home, Double Glazing or Triple Glazing?
If you seek the most energy effective window that you can get, and you have the budget plan readily available then Triple glazing is for you.
However, if you are budget mindful but still want good performance, a good quality A++ ranked double glazed window will be more than approximately the task.
In the UK climate, the included performance of a tripe glazed window is not truly that required to have. We do not actually suffer from extremes of cold, like Scandinavia for example.
The additional expense of triple glazing Vs double glazing, is not always going to be recovered by savings on your family bills, when compared to what you obtain from a good quality double glazed window.
Having stated that, if your regional installer is offering a good deal on rates, then I ‘d take the triple glazing if I were you.
You never ever know, the ever increasing expense of gas and electrical power, and the UK federal governments’ constant push towards ever more energy effectiveness, could make triple glazing the very best choice for the future.
