Triple Glazing Vs Double Glazing: Which is Better?

Thinking about upgrading to double or triple glazing, but just aren’t sure which ones to go for? Great! Here at MassimoSky, we want to make this clearer so you’re able to establish what the best options are. In this article, we will discuss the pros and cons of both glazing types and what you should be thinking before investing.

Double Glazing vs Triple Glazing

Key Features of Double Glazing

First, let’s start with double glazing. A double-glazed window is simply made up of two panes of glass and is the most common type of glazing in modern houses. Between the two sheets of glass, there is an air gap. This helps to control and insulate both temperatures inside and out. As the air will have minimal circulation, it reduces the speed of air convection and therefore decreases heat transfer.

Pros & Cons of Double Glazing

Before discussing which glazing you should go for. We think it’s important to understand the pros and cons of each type, so you have a full understanding of what you’re getting.

Pros of Double Glazing

Price – Double-glazed windows are found in most modern homes and there’s a reason for this, the price. It’s been said that a double-glazed window can be anywhere between 33 to 55 percent cheaper than triple glazed, making it much more affordable for your everyday homeowner.

Improved Insulation – If you’re upgrading your home from single glazed to double, it can improve your thermal efficiency. This is because a single glazed window doesn’t hold any insulation properties, whereas a double glazed has that “air pocket” that reduces air convection between the inside environment and out.

Return on Investment – Another great benefit when it comes to double glazed windows, is that it adds value to your house and helps you save on your energy bill. It’s been estimated that category B rated double glazing can save you approximately £110 – 140 a year on your heating cost.

Cons of Double Glazing

Better alternatives – Although double glazing can hold some great benefits and are good enough to insulate a house in the UK, there are better solutions. Upgrading to triple glazing is substantially better at holding heat, they just cost a great deal more.

Life tendency – In terms of comparing both double and triple glazed windows. A doubled glazing is more likely to become damaged through natural weathering and use. It has been said that triple glazing will approximately “outlive” double glazing by 10 years.

Strength – Even though double-glazed windows are reasonably strong. Triple glazing adds that extra layer of strength, protecting it better from both the natural environment and burglars.

Key Features of Triple Glazing

As you can probably tell, a triple glazed window has three panes of glass rather than two. As triple glazing will have three panes of glass, there an added layer of insulation. Instead of one “air pocket” there now will be two. So in theory, it will give you double the amount of insulation.

Pros & Cons of Triple Glazing

Triple glazing comes with an array of great benefits. But as with most things we benefit from, there are also negatives behind it. Let’s find out what these are.

Pros of Triple Glazing

Sound Insulation – Adding another layer of glass can massively increase the sound insulation of a window. This is why you’ll commonly see a house with this type of glazing near motorways.

Improved Thermal Energy – As mentioned above, they can add insulation by adding the third windowpane. Doing this can improve your thermal energy and in the long run save you money on your heating bill.

UV protection – This is extremely important for protecting your furniture and flooring. Triple glazing provides excellent protection when it comes to UV rays. This doesn’t just protect your furniture from sun damage but also keeps your home cooler.

Cons of Triple Glazing

Costs – Triple glazing is estimated to be a whopping 33 – 55 percent more than your traditional double-glazed window, making it the most expensive glazing out of the two.

Climate – It can also be considered “overkill” depending on where you live in the UK. For example, if you live in the highlands or near a motorway, you’ll reek more benefits from triple glazing than others.

Weight – If you’re someone that struggles to open windows, triple glazing isn’t for you. Typically a triple glazed window is a lot heavier than a single or double.

Which Glazing Should I Choose?

Now onto the question you’ve all been waiting for. Which glazing should I choose? Unfortunately, it’s not as straight forward as that and I really wish it was. However, it all depends on your situation. Where you live, how much money you want to invest and your contribution to the environment.

Personally, I would take into consideration the following;

  • Energy Efficiency
  • Noise Levels
  • Cost
  • Environmental impact
  • Return on Investment

We all know that energy efficiency is the goal behind upgrading into double or triple glazing. Although I’ve mentioned that triple glazing holds more energy, you’ll have to decide whether the cost of the triple glazing will be reasonable for how much energy you save.

For instance, if your house is already well insulated and doesn’t require a lot of thermal energy to heat it and keep warm. You’ll probably be better off investing in double glazing, as you’ll get a faster return on your investment due to the price being much cheaper.

The same goes for noise levels. If you’re a light sleeper or live close to a motorway, you’ll find more benefits from those who aren’t.

As you can see, it really does depend on your living situation. Take the notes above into consideration and then branch out to see which you can benefit from the best.
