A Brief Guide To Argon-filled Double Glazing & Energy Efficiency

Energy efficiency is a hot topic and homeowners are keen to do all they can to use less energy and therefore lower their utility bills. There are all sorts of things that people do to boost their energy efficiency, but one of the best and the easiest ways is to install new double glazing. Quality double glazed windows that are filled with argon gas help to keep heat in, allowing homeowners to turn the radiators down or even off, therefore lowering their energy consumption and reducing bills.

How are double glazed windows rated for energy efficiency?

The British Fenestration Ratings Council (BFRC) has set up a simple system to demonstrate how efficient double glazed windows are. A window with an A grade is excellent, while a G rated window is the least efficient. Under building regulations house windows must be rated C or above.

Why are argon-filled windows preferable?

The space between the two panes of glass in double glazed windows can be filled simply with air, or a gas can be injected in to it. Air-filled windows are the cheaper option, and do provide a certain level of energy efficiency and noise reduction. But argon-filled double glazing is a better investment for long-term energy efficiency and performance.

Argon is an inert gas and is quite nonreactive, which ensures the windows will stay effective for longer. In air, the oxygen can cause rust and corrosion in metal parts, meaning the windows become less efficient over the years.

Additionally, argon is more viscous than air. This means that molecular movement is inhibited, so heat transfer and heat loss are reduced. Furthermore, argon is denser and heavier than air, which helps to prevent against condensation.

All this means that argon is perfect for high quality double glazed windows and so homeowners should look for argon-filled units over air-filled ones where possible. This will give them better heat retention in their home, and therefore can help to lower energy bills. It will also mean that their new windows will last longer, making the investment better value over the years.

If you are considering replacing or fitting new double glazed windows in your home then take time to consider the different options and be sure to pick quality products that you know will last and add value to your home. You will not be disappointed with the benefits and could get a lot more enjoyment from your property.
