Low e has the ability to keep the temperature of the surface of the glass facing the interior very near that of the room itself regardless of outside temperatures.
Low e windows are a good investment in the midwest or east coast but in the southwest the best cost for the money is a good dual pane with at least a 1 2 air space install a high quality solar control film with a high total solar rejection and it is possible to reject as much as 80 of the heat gain it also helps keep the heat in in the winter.
When first invented in the 80s low e windows only came in one variety for one purpose.
To keep in the infrared light.
However low e coating is not a standalone material.

The windows are usually single pane but can be installed double pane at a higher cost per window.
The term double pane refers to a window that has two pieces of glass while low e is a coating technique.
Choose to add optional argon gas between the panes to act like an insulating blanket and reduce heat transfer.
This triple pane glass is filled with two layers of argon or krypton gas as well as two layers of soft coat low e.
Energy efficient windows use two or three panes of glass to slow conduction and maintain comfort.
In many cases windows in northern colder climates will have low e applied to surface 3 to prevent the heat on the inside from escaping out in the winter.
Soft coat windows have much better u value than hard coat surfaces and allow less uv transmittance by almost 75 over clear glass.
In other words this sheet can effectively turn a double pane into a triple pane and this insulation can be further supplemented with the addition of inert argon gas for even more r value.
