Difference Between Double Pane And Low E Windows

You can have glass with or without a low e coating.

Difference between double pane and low e windows.

While low e glass is generally cheaper than double glazing it will also reduce you winter heat gain leading to a need for either a bigger windows b more mechanical heating. However low e coating is not a standalone material. Now we have double and triple paned windows high efficiency windows and a wide variety of frame materials to choose from. The world of windows has come a long way from what it once was.

Double pane windows also known as dual pane windows come with two panes of glass. 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. The biggest drawback of low e windows is primarily cosmetic. If the inside glass temperature of an insulated unit is significantly lower than the room temperature it can give the occupants the feeling that the room is colder than it actually is.

A single pane window with window film won t match the insulation of a double pane window but it s better than a naked single pane window. The term double pane refers to a window that has two pieces of glass while low e is a coating technique. At 0 f outside the inside surface of double pane glass can be as much as 30 warmer than single pane glass but still 25 lower than low e coated glass. This is a short term solution that can provide an extra layer of insulation on any window.

The windows are usually single pane but can be installed double pane at a higher cost per window.
