If you’re upgrading your windows or building from scratch, one of the biggest questions you’ll face is whether to choose double glazing or triple glazing. It’s not always an easy decision, especially with energy prices on the rise. Many UK homeowners are wondering if that extra pane is worth it. Here is a breakdown of triple glazing and double glazing in Stevenage.
What’s the difference?
At its core, double glazing consists of two panes of glass separated by a gap. It is usually filled with argon gas to improve insulation. Triple glazing adds an extra pane (so three in total) and another gas-filled gap.
This extra layer ensures better insulation, less heat loss and improved noise reduction. However, as you’d expect, it also comes with a higher price tag.
Energy efficiency
Triple glazing does offer better thermal performance. However, the amount of energy saved may depend on your property.
If you live in a modern, well-insulated home in a colder part of the UK, then triple glazing could make a noticeable difference in keeping warmth in and reducing heating bills.
However, in a typical UK home with standard insulation, the jump in energy efficiency from double to triple glazing may be modest. High-quality double glazing can still perform exceptionally well, especially when paired with low-emissivity (low-E) coatings.
Noise reduction
Triple glazing can help reduce outside noise. However, it may not make a dramatic change. What matters most here is the thickness of the glass and the spacing between panes.
If noise is a significant concern due to living near a busy road or under a flight path, you can ask your door installer about acoustic glass options. It can be more effective than simply adding another pane.
Cost consideration
Here’s where many homeowners pause, as triple glazing can cost around 30-50% more than double glazing.
If you’re replacing every window in your home, that cost adds up quickly. For most people, double glazing offers the best balance between performance and price. It’s energy-efficient, cost-effective, and proven to work well in UK weather conditions. Quality double-glazed windows can provide you with almost the same benefits as triple-glazed windows.
Which one should you choose?
It depends on your goals:
- If you want to reduce your heating bills, both options can help. However, triple may save a bit more in the long run, especially in colder climates.
- With a budget, high-spec double glazing is still a great investment.
- When noise is bothering you, consider acoustic glass.
