Argon Gas: Why can it be used in double glazed units?
Argon gas increases the windows ability to insulate. Because argon gas does not conduct heat as readily as air, its thermal conductivity is 30% lower than air. It helps keep heat in during the winter and out in the summer.
No, argon gas is clear, colourless and odourless. Even if installed side by side you cannot see the difference between a window filled with gas and one not just by looking at them.
Numerous studies show that gas typically leaks out less than 1% a year. Over twenty years the window will have 80% of the gas still trapped inside it.
An emphatic no! Argon gas exists naturally in the air you breathe. It is both non toxic and inert.
Whilst energy savings are important, the real comfort benefit of gas filling is the increase in the inner glazing temperature. Raising the inner glass temperature eliminates or substantially reduces condensation on the glass. A warmer surface is also more comfortable to be near.
Unfortunately not, gas filled windows are manufactured using specialist equipment and not all manufacturers have these facilities, so when buying windows make sure your new window supplier can offer you the benefits of argon gas for extra insulation.
Its presence in air was suspected by Cavendish in 1785, discovered by lord Raleigh and Sir William Ramsay in 1894. The gas is prepared by the fractionalisation of liquid air, the atmosphere containing 0.94% argon.
Argon is also used as an inert gas shield for arc welding and cutting, as blanket for the production of titanium and other reactive elements. It is also used in electric light bulbs and in fluorescent tubes.
