Thermal Insulated Windows, Why do the Manufacturers use Argon Gas between the glass window panes ?

Answer 1

it conducts less heat than plain air.

Answer 2

NO IT DOES NOT LEAK! See below.

It is used for extra R value ("R" ,insulating value=measurement of heat flow through a surface) it helps with noise level as well. It, combined with Low-E glass will give you the same R-value as triple pane glass without the added weight of a 3rd pane of glass. If, by chance it is allowed to leak it is because the seal of the 2 panes of glass has been broken down. (It is an inert gas) The seal can be broken down due to the way the glass is put together and 'sealed' at the factory. Many types of sealants are used to do this, it depends on the manufacturer. There's also silica gel in the spacer to help prevent moisture from collecting on the inside of the panes when sealed, once you start seeing the moisture between the panes, the seal has failed therefore it would have to be re-glazed. Most glass shops do not have the ability to replace the "gas", some do, so generally when you have a seal failure you will need to have it replaced by ordering it from the local building supply house which carries your specific brand of window. 30+ years in the window business.

Answer 3

It insulates a little better than air and also helps reduce noise. With the improved sealing materials available today the Argon does not leak out as bad as the windows made years ago and many manufactures will give a life time warranty on the sealed glass.

Answer 4

Argon is a very heavy gas and thus the molecules are closer together to prevent any penetration of air. and inhibit any leakage of the gas through minute holes or leaks within the window.

Answer 5

This is a selling point. The energy you save is not worth the extra money and it will leak out in a couple of years.

Answer 6

Probably so you don't get any condensate between the panes of glass.

Answer 7

supposed to stop fog on windows
