Difference between double pane and low e windows.

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. Double pane windows also known as dual pane windows come with two panes of glass. The term double pane refers to a window that has two pieces of glass while low e is a coating technique. This is a short term solution that can provide an extra layer of insulation on any window.

The biggest drawback of low e windows is primarily cosmetic. The windows are usually single pane but can be installed double pane at a higher cost per window. No longer do we simply choose a single pane wood window and call it a day. However low e coating is not a standalone material.

You can have glass with or without a low e coating. 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. 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. Double pane windows can be clear tinted or have a low e coating.

The world of windows has come a long way from what it once was.
