When it comes to upgrading your windows, you’ve probably heard about double-glazing and triple-glazing. So, what’s the difference? And, more importantly, which one is best for you?
Let’s compare triple glazing vs double glazing in a way that makes sense, so you can feel confident about your decision.
What’s the difference between double-glazing and triple-glazing?
Double-glazing has two panes of glass, ZEN’s also has a filling of insulating argon gas in the void between. Double-glazing technology has been revolutionary in making homes warmer - cutting down on energy bills, and reducing outside noise. It’s still by far the most popular domestic glazing choice in the UK.
Triple-glazing adds an extra pane of glass and another layer of gas. It’s basically like double-glazing with a bonus – offering even better insulation and noise reduction. But, it comes at a significantly larger upfront cost and the gains are much smaller than the huge performance jump from single to double-glazing.
Recent leaps in glass coating technology has meant that double glazing is so thermally efficient, you would normally only need to consider triple glazing if there is a compelling reason or your own special requirements.
Do You Really Need the Extra Pane?
Both options are a huge step up from single glazing, but here’s the deal: triple-glazing takes the insulation a fraction higher. It’s designed to trap even more heat inside, which can be a big plus if your home loses a lot of warmth through the windows.
But here in Bristol, our winters are chilly, not Arctic. For most homes, double-glazing is more than enough to keep you cosy and your energy bills down. Triple-glazing might be worth it if your house gets extremely cold, or you just want to go all-in on energy efficiency.
“Check the U-value on any windows you’re considering. The lower the U-value, the better it’ll keep the heat in. Triple-glazing usually has a small edge there.”
How About Noise Reduction?
Do you live near a busy road or have noisy neighbours? If so, triple-glazing can be a good option, but double glazing with acoustic glass actually has the edge here!
Double glazing with a larger outer pane (typically 6.8mm acoustic laminated glass) and 4mm inner pane, actually disrupts sound waves hitting the glass more than triple glazing which has 3 panes of 4mm glass!
Our standard double-glazed windows do a superb job of reducing everyday noise and for most people, it’s all they’ll ever need. But if you’re craving maximum peace and quiet – or maybe work from home and need a super calm space – triple-glazing or acoustic double glazing is worth considering.

Let’s Talk Costs
We won’t sugar-coat it: triple-glazing and acoustic double-glazing costs more than double-glazing. It’s down to the extra materials and the additional time it takes to make and install them.
Double-glazing will always be the more value-friendly choice and delivers fantastic energy savings and comfort. But if you’re planning to stay in your home long-term and want the ultimate in performance, triple-glazing could pay off over a long time.
“Did you know? All our double-glazed windows are A-rated as standard, meaning they offer a high level of energy efficiency. In fact, the energy performance difference between these and triple glazed options are much smaller because of breakthroughs in material technologies like low emissivity glass coating technology.”
What About Window Frames?
It’s important to remember that Triple-glazed units are heavier than double-glazed ones. That means your window frames need to be up to the job.
uPVC windows and doors can handle double-glazing without a problem. But for triple-glazing, you may need stronger hinges to support the extra weight. Don’t worry – when you work with us at ZEN, we’ll guide you through what’s best for your home. That’s what we’re here for.
Appearance
Good news – both double- and triple-glazed windows come in loads of different styles, so you don’t have to compromise on looks. Whether you’re going for something sleek and modern or a more traditional look, we’ll make sure your windows fit your home perfectly.
What’s the Environmentally Impact?
You’re probably wondering about the eco-side of things. Triple-glazing is super energy-efficient, but it does take more materials to make, so there’s a trade-off. Double-glazing still delivers great energy savings while being lighter on resources.
“Breakthroughs in glazing technology have ushered in a new era of extremely efficient windows which is why there is currently far less talk of triple-glazing. There is also a lower carbon foot print in double-glazing production and the lighter weight of the glass sealed units is easier on moving parts like hinges.”
Triple Glazing or Double Glazing?
Ultimately, the choice between double-glazing and triple-glazing depends on your priorities and budget. Here’s a quick summary:
A rated (double glazing) | A+ rated (double-glazing) | A++ rated (triple-glazing) | |
Energy Efficiency | Excellent for most homes | Excellent for most homes | Superior for extreme efficiency |
Noise Reduction (db) | Noise reduction 31db | Noise reduction 31db | Noise reduction 37db |
uValue | 1.4 | 1.3 | 1.0 |
Glazing Cavity Fill | All glazing units are argon filled and sealed | All glazing units are argon filled and sealed | All glazing units are argon filled and sealed |
Cost | Affordable for many, great investment | +15% extra upfront cost | +40% extra upfront cost (compared to A rated double) |
