Double Glazed Sealed Units

What is Double Glazing?

Double glazing is often used in many glass installations, especially in windows. It consists of two panes of glass within the same frame, with a thin layer of air (filled with argon gas). This gap is what makes double glazing so effective.

Double-glazed units keep your home warm. They trap heat inside and block the cold from coming in and also cuts down on drafts. This is a big step up from single glazing, which has just one glass pane 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

Homeowners often ask how well double glazing cuts heating costs and saves money. Upgrading to double glazing usually aims to cut energy costs. But it also boosts security and sound insulation. These benefits, however, are tougher to measure.

Some studies show that double glazing can cut noise by 35 decibels or more. That's about the volume of a normal conversation. This can be very helpful if outside noise bothers you. When it comes to reducing heat loss, there are clearer figures to consider. Savings and energy conservation depend on your property's size and typical energy use.

Research from Confusedaboutenergy.co.uk shows how effective double glazing can be. A 3-bedroom gas-heated home uses about 15,000 kWh of energy each year. With double glazing, it could save around 10% on energy costs. This would equate to a saving of around £70 per year.

A bigger home that heats with electricity uses around 20,000 kWh yearly. It can pay back the cost of double glazing in over 16 years. Double glazing functions in a unique way in each home. It depends on how much energy the house uses. Still, it can be a good long-term investment.
