Cleaning Low E Windows

Cleaning low e windows ?


I just bought an older house with new double pane windows that the previous owners had installed and due to the remodel they are very dusty and in need of a good window cleaning.

I noticed that on the windows they say that they are low e windows. I know that the low e means that they are some type of energy saving windows that help to reduce the different heat exchanges.

These are vinyl windows and the brand name is Jeld-Wen. My questions have to do mostly with cleaning. Just because they are low e windows, should they be cleaned in a special way? Should I be using a special window cleaning solution as well?

Cleaning Low E Windows

You are right about the low e windows, they are energy saving windows. As technology progresses we will continue to find more and more advanced energy saving double pane windows on the market.

Low e stands for low emissivity. Low e windows are designed to reduce the harmful UV and infrared spectrums while allowing most of the good visible light to pass through helping your house stay cooler in the summer and warmer in the winter thus reducing energy costs.

Low-E energy saving windows comprise of several microscopic layers of silver nitrate that are molecularly adhered to the surface of the glass during the manufacturing process. The glass maybe somewhat darker than non low e glass but it’s hardly even noticeable.

I have had no personal problems to this day cleaning low e windows or any other energy saving windows while using standard professional window cleaning techniques although, I always continue to remain cautious.

As far as I know from my own research, the actual coatings are located on the inside surfaces of the window and are not exposed to the elements. Therfore, the coatings should not be damaged or effected in any way by standard window cleaning methods.

Because you had mentioned having Jeld-Wen brand windows, I have listed below a video from home improvement expert Danny Lipford. He is talking about the Jeld-Wen brand which seems to confirm my understanding of this type of window. (Keep in mind that this video is for the Jeld-Wen brand and that other brands of windows may be different.)

Because I have read about different situations and comments that raise concern when it comes to cleaning low e windows, I will always use great caution. If there is anything that seems unfamiliar or out of the ordinary that causes any doubt, always do extra research and by all means call the manufacturing company to find out what precautions you should use while cleaning their brand of windows.
