Latest figures show that triple glazing is 40 percent more energy efficient than double glazing. In other words, the mere addition of an extra pane and high-performance frames will ensure that your home will stay warmer for longer and therefore use less fuel. It is also worth bearing in mind that your carbon emissions will be reduced as well.
For those of you that only want to know that triple glazing will make your home warmer, safer and quieter as well as adding value to it, then perhaps you ought to check out our introductory guide to triple glazing.
However, if you want to dig deeper into the scientific stuff and cast your eyes over Government figures and ratings, then we urge you to read on.
How Does Triple Glazing Work?
You have probably noticed over recent years that many products now feature a bar graph either on the unit itself or the packaging.
This includes articles like sizeable ‘white goods’ such as a fridge, oven, freezer, dishwasher, tumble dryer and washing machine. Boilers are also included.
At the other end of the scale, you will find small products like a light bulb for example. The simple idea is that the graph gives you an easy to understand, at-a-glance evaluation of how energy efficient a particular product is. Window glazing is no different.
So, let’s delve a bit deeper into the technical data. Here is the bar graph for an average triple glazed window from Scandinavian Windows.
A Rating Scale with A++ Selected
The rating scale is from the green A bar at the top to the red G bar at the bottom. When it comes to windows, this rating takes into account the frames as well as the glass. As you will have guessed, A is good while G is the window equivalent of just having a gaping hole in the wall. These ratings can be sub-divided into plus or even plus-plus.
At Scandinavian Windows, we wanted to be the best of the best. We did not just aim for the A rating. We wanted to beat A+ and ensure that all of our triple glazed windows are worthy of an A ++ rating.
Put it this way; there is no better level of efficiency on the market than A++.
Triple Glazing U-Values?
Windows are also given a U-value rating. This measures how easily heat (or cold) can pass through the panes of glass.
It shows how efficient the window unit is at retaining warmth inside and transmitting solar energy from outside. The perfect balance, of course, is for the heat from sunlight to be beamed into your home – it is free after all – while the heat produced by your radiators and/or fires is reflected back into the room and not conducted to the outside. More warmth from sunlight entering the room and less heat that you have paid to produce leaving the room will mean you reduce your energy bills. Simple!
The lower U-value numbers are best. For example, a window with just a single pane of glass has a U-value of more than 5. The cold temperature outside is easily transmitted inside or, vice versa, the heat you are producing inside your property quickly escapes. Most of you will be familiar with condensation streaming down windows on a cold day. Warm, moist air causes this in your home when it comes into contact with the cold window.
Double glazing, as you would expect, performs better than just a single pane of glass. The sort of units in most houses today will have a U-value of around 3. Okay, it is better than a single pane but, when compared to triple glazing, that sort of figure nowadays is a pretty poor.
So, what about the triple glazed units installed by Scandinavian Windows? All of our units with Argon gas and Soft Coat Xtra glazing, fitted into multiple internal chamber frames, have an amazing U-value of 0.8. The heat stays inside; keeping the cold air outside at bay. Scandinavian Windows can reduce your home heating bills by as much as 40 percent. You keep your money in your pocket!
Is Triple Glazing Worth It?
If you travel to somewhere like Norway or Sweden, you will find that when new homes are built or when the glazing is replaced, triple glazing is now standard. That is also why homeowners who are looking for minimum energy loss to reduce energy costs, as well as staying warm, are turning to triple glazing.
Of course, it all comes down to expense. THAT is where you win with Scandinavian Windows. We supply and fit triple glazing for the same price as double glazing.
If that wasn’t enough, we also have the best product on the market with a 15-year guarantee. Our service has been honed over thirty years meaning we design right, measure right and fit right.
