Are three panes of glass better than two? Read Double Glazing on The Webs guide to Triple Glazing to find out whether this glazing is the right solution for your property.
Double glazing is already seen to be far more energy efficient than single glazing so upgrading your windows from two panes to three makes sense right? Not necessarily.
Is Triple Glazing Worth It?
Triple glazing is made from 3 panes of glass instead of 1 (single) or 2 (double glazing.) The extra pane is supposed to increase efficiency whilst reducing noise.
However, double glazing will allow you to see a significant improvement in your homes efficiency but it can take a lot of time to see the benefits.
So would it really make that much of a difference?
Double glazing Or Triple Glazing?
Both have their own benefits but the real ‘trade-off’ is between initial costs and ongoing savings that can be achieved in the long run.
The main difference is in their different levels of thermal insulation. Triple glazing windows will mean your home is marginally more energy efficient. However, as we mentioned before, you aren’t likely to see the effects of this straight away.
Triple glazing is probably sold more on the idea of comfort in the home. It will certainly improve all round comfort in terms of warmth, and noise reduction. Cold spots and draughts? Eliminated with triple glazing.
What is A U-Value?
A U-value in physics is used to represent internal energy. All building materials are measured using U-values and the lower the U-value, the less heat is lost.
Triple glazing is known to have a lower U-value than secondary glazing and double glazing but although a U-value may sound impressive, the additional energy you will be saving will be little in terms of the payback time.
In Scandinavia, triple glazing is installed as standard. This modern glazing takes the U-value of windows down to around 0.8 – a considerable improvement on standard windows.
Of course, in the UK our weather conditions aren’t as extreme so changing from double glazing to triple glazing may be a waste of money.
If you already have efficient double glazing then there is no need to replace it with triple glazing.
Cost of Triple Glazing
This type of glazing is more expensive. This is down to the additional glass, weight and frame. You may also be limited in terms of windows style as not all window designs are manufactured with this glazing in mind.
Also, don’t forget that more panes of glass means less daylight. This is certainly a factor to consider-triple glazing may make your home darker. Light transmittance will only be diminished slightly but this can be a problem if you are looking to enhance natural light within your home.
- It is higher in cost
- Can reduce light penetration
- Carries a greater weight
Benefits of Triple Glazing
- Noise Reduction: Provides superior noise reduction compared to other glazing, with additional upgrades available
- Low U Values: Low U-Values so is recommended for house projects focused on energy efficiency
- Greater Thermal Insulation: for a more comfortable home.
Where Can it Be Installed?
Triple glazing can be used for windows, doors and even walls of glass. Although triple glazing weighs more than standard glazing, adjustments to the frame can be made by your supplier. In vertical glazing such as windows or doors, the walls can easily carry the extra weight.
If you are looking to replace a traditional set of windows then double glazing will provide you with a better match. Double glazed frames are slimmer so will provide you with a more authentic look.
