Double Glazed Sealed Units

What is Double Glazing?

In simple terms, double glazing is commonly used in various glass installations, especially windows. It consists of two panes of glass within the same frame, with a thin layer of air (or sometimes an inert gas like argon) between them. This gap is what makes double glazing so effective.

Double glazing helps to keep your home warm by trapping heat inside and blocking the cold from entering. It also reduces drafts, offering a major improvement over single glazing, which only has one glass pane acting as a barrier. If you've ever had single-glazed windows, you know how chilly they can make your home in winter. Double glazing provides better insulation, making your home more comfortable year-round.

What are the Benefits of Double & Triple Glazing?

✅ Energy Efficiency – Helps regulate indoor temperatures, reducing heating and cooling costs.
✅ Noise Reduction – Ideal for busy areas, significantly lowering external noise levels.
✅ Enhanced Security – Additional layers of glass make windows more resistant to break-ins.
✅ Condensation Prevention – Sealed units help minimise moisture build-up on windows.
✅ UV Protection – Reduces harmful UV rays that can fade furniture and flooring.

The Efficiency of Double Glazing

For many homeowners looking to reduce their heating bills, the main question about double glazing is how effective it really is and how much money it can save. While the primary motivation for upgrading is often to lower energy costs, double glazing also offers benefits like improved security and sound insulation—though these advantages are harder to quantify. Some studies suggest double glazing can reduce noise by anywhere from a small amount to as much as 35 decibels—about the level of a normal conversation, which is especially helpful if you're bothered by noise outside your home.

When it comes to reducing heat loss, there are clearer figures to consider. The amount of money you can save and the energy you can conserve depends on factors like the size of your property and your typical energy usage.

Research from Confusedaboutenergy.co.uk gives a good indication of how effective double glazing can be. For example, a 3-bedroom gas-heated home that uses around 15,000 kWh of energy annually could save about 10% on energy costs with double glazing. This would equate to a saving of around £70 per year.

On the other hand, a larger home that uses electricity for heating and consumes an average of 20,000 kWh per year could expect to recoup the cost of double glazing in just over 16 years. This makes it clear that the effectiveness of double glazing varies based on your home and energy usage, but it can still be a valuable long-term investment.
