Difference Between Double Pane And Low E Windows
With that said we highly recommend double pane windows over single pane windows if you live in a colder climate.
Difference between double pane and low e windows. The biggest drawback of low e windows is primarily cosmetic. You can have glass with or without a low e coating. The panes are typically separated by a gap that measures from inch to inch. The windows are usually single pane but can be installed double pane at a higher cost per window.
So it not only acts as a reflective low e window but also as a form of thermal insulation against drafts and heat loss. However the most common application area is in between the two panels of a double pane window. Double pane windows increase the energy efficiency of homes because the panels set up a barrier to reduce heat loss in winter and heat gain in the summer. When you upgrade your current windows to double pane windows you re going to notice the difference.
The thing is triple pane windows with their three panes of glass do a better job than double pane windows on preserving energy within your home. A double pane window has two sheets of glass and a gap of air in between the panes. 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. A standard double pane window with argon gas is going to reflect 90 of the energy and only let 10 through.
The term double pane refers to a window that has two pieces of glass while low e is a coating technique. It requires a sheet of glass as a base material for its application. This is but a small sampling of how specific the new generation low e coatings can get. 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.
It s not actually a coating so much as a thin sheet suspended in the middle of the panes. Low e squared glass can keep the inside glass temperature within 1 f of a room with no windows. However low e coating is not a standalone material.
