The benefits of Low “E” Double Insulated Windows

Some of us remember growing up with windows in our homes that were a single pane of glass. During the frigid winters, you couldn’t go near the window because it was the coldest place in the house. During the summers, it was the hottest place in the house not to mention having to clean them with the dividers in them which was usually my weekly chore.

Today I still have the weekly chore of cleaning the windows however, technology has brought us a long way and today’s widows aside of being able to view the outside world from the inside has come a long way.

Low E Double Insulated Windows have several functions. Not only are they good for your pocket book, noise reduction is vastly improved and most chromium windows provide a “Tinting” of the glass making it difficult to see inside your home during the daylight hours. It is the property of “Heat” reduction and energy savings that I would like to discuss in this article.

All spectrums of light produce heat. We are most familiar with “Visible” light which actually represents a very small or narrow band width in the spectrum.

As we move up the band width or to the right we come to the UV or Ultra Violet frequency which creates a lot of heat and that is not the only property. UV can fade your carpet, furniture and many other items in a direct line as light enters your home through your windows.

Low “E” (Emissivity) windows are double paned, chromium plated and Argon filled to stave off the effects of UV radiation. This picture should help illustrate how this works.

As you can see, visible light is unimpeded and enters the home with very little being reflected back out while the majority of UV radiation and solar heat are prevented from entering. During the summer months, Low E glass can block as much as 96% of the heat generated from UV light and up to 86% of Ultra Violet light. This assists your HVAC system cooling your home and running much more efficiently resulting in savings to you.

As a demonstration, during the afternoon when I have customers in to view our community I always demonstrate Low E windows and how they work. When the Sun is in the western sky beating down on the glass, simply walk in front of the windows and notice how much hotter it is as it reflects from the windows. It is actually very noticeable. Once inside the home I will open a window slightly and have the customer place the back of their hands on the inside pane and then compare that to the exterior pane. It is incredible the difference in the temperature of both panes.

Bayway homes installs Low E double insulated windows in all the homes that we build. Utilizing this technology along with many other applications used to produce a more energy efficient home is our goal.
