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.
Difference between double pane and low e windows.
Double pane windows can be clear tinted or have a low e coating.
However low e coating is not a standalone material.
The world of windows has come a long way from what it once was.
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.
No longer do we simply choose a single pane wood window and call it a day.
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.
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.
Now we have double and triple paned windows high efficiency windows and a wide variety of frame materials to choose from.
This is a short term solution that can provide an extra layer of insulation on any window.
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.
The biggest drawback of low e windows is primarily cosmetic.
