What is Triple Glazing
Triple Glazing is exactly what the description says , triple glazing is 3 panes of glass instead of 1 (single glazing) or 2 (double glazing). In this article we will look at Triple Glazing Costs and if Triple Glazing offers further value. It is widely understood that having that one extra pane, you will increase energy efficiency and reduce noise.
We already know that double glazing makes a significant improvement over single glazing, we also know that double glazing units are deeper then single units and can take up more room, in the same way Triple Glazing will add extra depth to a window frame and it is rarely retro fitted to existing frames.
So Why Are Triple Glazing Costs Important
We all understand that in general glazing technology has moved forward leaps and bounds over recent years, with a real focus on delivering real returns on investments, glazing is not cheap and energy prices have been falling. Even so upgrading from single to double glazing can take a long time to recoup expenses when looking at energy efficiency, or reduced energy bills alone. So would making the jump to triple glazing make that much of a difference?
U-Value Energy Efficiency
The common method of measuring energy efficiency of windows is a U-Value, the lower the U-Value the more energy efficient the double glazing. Typically, single glazing has a U-value of around 5, older double glazing units have a U-value of about 3 and the newer more modern double glazing units will have a typical U-value of around 1.5 to 1.6. Triple Glazed units are deemed to be more energy efficient with a U-Value typically between 0.8 &0.65
These efficiency ratings reflect the changes in double glazing technology in recent years and the industries drive improve glazing performance. The Double glazing improvements have been made through a range of optimisation throughout the window cavity, introducing the use of low emissivity coatings, using inert gas to fill the gap between pains, and using aluminium spacers or ‘cold bridges’.
Independent Research conducted by the PassivHausInstitute in Germany looked at the Physics involved and has indicated what happens to surface temperatures on various forms of glazing when it gets really cold outside, and the internal air temperature is designed to be at 21°C:
- Next to a single glazed window, the internal surface temperature is around 1°C.
- Next to a double glazed window (2000 vintage), the surface temperature is around 11°C.
- Next to a modern, energy-efficient double glazed window, the surface temperature is 16°C.
- Next to a triple glazed window, with a centre-pane U value of just 0.65, the temperature is 18°C.
So you can see that whilst a double glazed window is perfectly adequate, a triple glazed one is just that much more comfortable, because it hangs onto heat just that little bit better. So whilst triple glazing may make little difference to your heating bills, you will notice the difference inside the house.
These movements in glazing technology has brought down the U-value of modern double glazed windows significantly, so if the question is “does that make triple glazing worth it”, if the U-value of double glazing is now so much more improved? Well, walls have a u value of around 0.3, so it is clear that windows have a long way to go before they are no longer a weak point in the efficiency of the building.
Does installing triple glazing pay?
In colder weather then triple glazing will add extra comfort in the home, that’s why In Scandinavia, triple glazing is now pretty much the standard, with modern triple glazing taking the U-value of the windows down to around 0.8. This is a considerable improvement on even modern double glazing. Lots of new homes are now being built with triple glazing and it is generally acknowledged as being better. Each home is now measured for its energy efficiency and the buyer’s information pack will contain details of energy efficiency ratings when you come to buy a new home, that’s one reason why new home builders are adding triple glazing, to ensure their homes reach maximum value at the time of selling.
Triple Glazing Costs – Is it worth it
Triple Glazing is the Warmest
Triple Glazing is the warmest with A+ rated energy efficiency, the the extra glazed pane, insulated frame and manufactured quality of our windows will help to maintain heat and maximise energy efficiency.
Triple Glazing is the Safest
Every triple glazed window supplied by Carrington Windows comes with an extensive guarantee. Our Triple glazed units exceed the recommendations of the National Police Project “Secured by design” The extra pane makes these windows a lot harder to break, giving you and your family extra peace of mind.
Triple Glazing is the Quietest
Tiered of being woken by outside noise, or do you want to keep your noise inside? the extra glass pane in the Carrington Windows Triple Glazing serves to block out even more noise than our double glazed windows and will give you or your neighbours that un interrupted sleep that we all hold so valuable.
Triple Glazing is the most Secure
Carrington Windows triple glazed windows feature a multi-point locking system as standard, our triple glazing windows come with a unique 10-point locking system with deadbolt security and a £1,000 anti-intrusion cover guarantee. This is an improvement on the Duraflex 8-point locking system that is standard on our double glazing windows, which will make your home even more secure than ever before.
Triple Glazing Costs – Summery
Triple glazing windows have an improved thermal energy rating of A+9 as opposed to our double glazing, which has a thermal energy rating of A+2.
Not sure what that means? Here’s the jargon-free version: Triple glazing is 40% more efficient than standard A-rated double glazing, and can save you up to £755 a year on heating.
