Yes if you compare it with a double pane sealed window.
Double pane low e argon windows.
The biggest drawback of low e windows is primarily cosmetic.
Low e windows are covered in a film like coating that traps warmth prevents drafts and reflects sunlight in the summer to aid in cooling the home.
Is the thermal resistance factor better.
Double pane windows are the solution for old inefficient windows.
Double glazed low solar gain low e glass.
To keep in the infrared light.
Insulated glass windows also called double pane glass typically have an r value of around 2 0 to 3 0.
When combined together low e and argon gas make a formidable team to combat both cold and warm weather.
Combining low e and argon.
Replacement windows these days are often sold as double pane versions that not only feature two panes of glass compared to one on single pane windows but also are filled with argon gas in between the panes.
Regardless of the season low e argon gas windows ensure the climate is stable in your home.
Being cheaper argon is usually used to fill the wider 1 2 inch spaces between panes in double pane windows while krypton with its better insulating quality is often used for the thinner 1 4 or 3 8 inch spaces between panes on triple pane windows.
It requires a sheet of glass as a base material for its application.
Double panes of glass in addition to a layer of a gas is the best way to insulate a window.
When first invented in the 80s low e windows only came in one variety for one purpose.
W 2500 series primed wood double hung window w natural interior and low e glass model z40049.
Low e or low emissivity coating is a unique microscopic glaze that helps minimize the amount of ultraviolet infrared and visible light from penetrating the glass keeping you cooler in the summer and warmer in the winter.
Energy efficient low e argon thermopane windows are thus a product that effectively controls temperature variations.
The higher the number the more efficient.
This figure illustrates the characteristics of a typical double glazed window with a low solar gain low e glass with argon gas fill.
You can have glass with or without a low e coating.
However low e coating is not a standalone material.

How does it heat the home.
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.
R value is the measurement of thermal resistance.
As with moderate solar gain low e glass these windows are often referred to as spectrally selective low e glass due to their ability to reduce solar heat gain while retaining high visible transmittance.
The windows are usually single pane but can be installed double pane at a higher cost per window.
Argon typically represents a better value overall especially with double pane windows.
