Difference Between Double Pane And Low E Windows

The biggest drawback of low e windows is primarily cosmetic.

Difference between double pane and low e windows.

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. 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. Double pane windows can be clear tinted or have a low e coating. The windows are usually single pane but can be installed double pane at a higher cost per window.

The world of windows has come a long way from what it once was. However low e coating is not a standalone material. 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. The term double pane refers to a window that has two pieces of glass while low e is a coating technique.

The bigger windows solution can then create additional heat loss issues leading to a downward spiral in performance coupled with an increase in costs. 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. 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. This is a short term solution that can provide an extra layer of insulation on any window.

No longer do we simply choose a single pane wood window and call it a day.
