Not sure if triple glazing is the right option for you? A relatively new style of window, triple glazing is becoming increasingly popular. The majority of our windows are available with triple glazing as an option over double glazing, but what exactly is the difference between the two?
To help you understand more about why triple glazing could be right for you and how it could benefit your property, here are the answers to the most common questions we get about this glazing type.
Which is best, double or triple glazing?
A better question to ask than which type of glazing is best is which option is best for your property? Both double and triple glazing have a range of benefits so it is worth doing a full comparison to assess which will work with your home.
One of the main things to note is that triple glazing can be up to 40% more thermally efficient than high-quality double glazing. This means you can save a lot of money heating your home and that triple glazing is a great option for large windows that typically lose a lot of heat. Ultimately, this means that you could save a large amount of energy throughout the life of your windows.
However, because triple glazing contains an extra pane of glass compared to double glazing, windows tend to be heavier and thicker. This can mean that transportation and installation are more expensive, as well as the windows costing more upfront.
Does triple glazing soundproof?
Triple glazing can help to limit the amount of outside sound that can be heard in your house, making it a great choice for noisier areas or if you simply want to enjoy a bit of peace and quiet.
Sound waves travel through the air and cause vibrations in what they hit, which can cause the sound to travel through some materials. Glass is a material that sound can travel through, however, the more glass there is, the harder it is for sound to travel from one side to the other.
The extra pane of glass in triple glazing means that sound waves are weakened, which causes the sound to be quieter – if it actually manages to get through the glass at all. This means that triple glazing is ideal for those looking for a more soundproofed option.
Do you get condensation with triple glazing?
Because the thermal performance of triple glazing is so good, you can sometimes get condensation on the outside of your windows. This is because the outer pane of glass is not being warmed by wasted heat so it gets cold, which can lead to condensation forming on the outside of your window. This actually shows you that your windows are working well at keeping the heat in.
With double or triple glazing, you shouldn’t get condensation between panes of glass. If you do experience this, it is due to the seal breaking down. This allows water vapour to enter the cavity, which results in condensation. Luckily, this can be dealt with by having a replacement seal fitted.
Sometimes people experience internal condensation on the room side of their windows. This has nothing to do with how good the glazing is as it is caused by high humidity in a property. Rather than looking at your windows as the problem, you need to consider how ventilation throughout your property could be improved, as this will help to reduce humidity. Even simple steps like using a fan in your cooker hood when cooking can make a big difference.
Does triple glazing add value to your home?
Triple glazing can help to add value to your property in a couple of ways. To start with, the fact that it helps with soundproofing can make your home much more desirable to buyers, especially if the property is located in a busy area, near a road or close to a regular flight path. Having triple glazing already installed allows you to demonstrate how quiet your home is even with the outside noises.
On top of this, the energy savings that come with triple glazing also help to increase the value of your property. Triple glazing will have an impact on your energy performance certificate (EPC) rating, which will be a big plus to buyers.
While the added value may not be huge, it can have a big impact when you combine triple glazing with other energy-saving features to demonstrate that it costs less to run your house compared to other properties in the area.
How many years should triple glazing last?
There’s no exact answer to how long triple glazing will last as it can depend on several factors, including the manufacturer and how your windows are cared for. Maintaining your windows will help to ensure they last as long as possible.
On average, triple glazed windows can last anywhere from 10 to 35 years, with higher quality windows that are looked after being at the top end of the scale. You’ll find that, as with any windows, the appearance of triple glazing can last longer, although they may lose some of their energy efficiency after a couple of decades due to gas escaping from the panels. However, this happens slowly over time so triple glazing is still a great investment.
