Low E-Glass for Windows

Windows let the light in, but they also let the heat out during the winter. A product known as low e-glass for windows is making a dramatic change in this area.

Windows seem like fairly simple things, but they can become very complex when you start looking at them. Most of this is down to the design and shape of the window in question, but all of them have a universal problem. Glass is not a good insulator. It allows for heat exchange. If you have the heat on, it can seep out through glass during the winter. The opposite is true when you have the air conditioner on in the summer. Either situation, of course, starts adding digits to your utility bill.


The 1970s were a revolutionary time in windows. Why? Well, we have to look to history to get the answer. The 1970s were a period with a ton of turmoil. One area that gets less attention than problems with wars and Presidents is the energy market. We had oil embargoes and fuel prices were through the roof. People started really looking at their utility bill and demanding improvements in ways to lower those bills.

The first development was the double pane window. The two glasses were separated a bit and this created a pocket of air. Although it might not seem like it at first, air can be an insulator. In the case of these windows, the air knocked down energy loss by fifty percent or more in certain situations. Ah, but then e-glass came along.



E-glass was another approach to fighting the insulation problem with windows. The air concept improvement was a good one, but not a final answer. E-glass uses a much better approach in that it eliminates the air pocket and replaces it with…metal. The pane of glass has an ultra thin layer of metal in it. The metal repels the heat that is trying to escape through the window. It sounds odd, but it works.

Low e-glass for windows refers to a type of this glass. It is designed to be the top of the line approach [and comes with an appropriate price]. Regardless, it will provide nearly twice as much insulation as a double pane window, which means your utility bill will drop significantly.
