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.
Difference between double pane and low e windows.
You can have glass with or without a low e coating.
This is a short term solution that can provide an extra layer of insulation on any window.
The bigger windows solution can then create additional heat loss issues leading to a downward spiral in performance coupled with an increase in costs.
However low e coating is not a standalone material.
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.
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.
Double pane windows can be clear tinted or have a low e coating.
No longer do we simply choose a single pane wood window and call it a day.
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.
The windows are usually single pane but can be installed double pane at a higher cost per window.
Now we have double and triple paned windows high efficiency windows and a wide variety of frame materials to choose from.
Double pane windows also known as dual pane windows come with two panes of glass.
The biggest drawback of low e windows is primarily cosmetic.
