Energy Saving Windows

Installing Low-E Storm Windows

High energy costs are a problem that plagues homes across the entire globe. Whether it is energy wasted trying to heat a house during the winter, or energy lost trying to cool it off during the summer; a lot of energy is spent trying to maintain a comfortable temperature in your home. There are a lot of factors that play a part in determining how much it costs for a home to maintain a steady temperature. One such factor is the windows in the home.

Retrofitting Existing Windows To Preserve Heat

If you are experiencing the crushing burden of high energy costs or just want to gain some extra savings, then improving your windows is a great option. The number of windows you have, their size, type of glass, and their location all impacts their effectiveness. Replacing or installing new windows entirely can be pretty costly, but there are other options.

For example, if you were to install new R5 windows in your home, you would see a noticeable decrease in energy costs. However, the expense of the installation and the cost of the windows would mean it could take up to 20 years for the window to pay for itself. Windows of this nature may take $5,000 or more to install in an average home.

Low-E Storm Windows – An Affordable Solution

A more practical solution is adding a new low-E storm window to your existing window. These are windows designed with a low budget and big performance in mind. They cost less than half the price of an average window replacement and can have nearly the same impact on energy performance. In the case of a low-E window, it typically takes between 5 and 7 years for the window to pay for itself.

What exactly is a low-E storm window? Simply put, a normal storm window is a glass casing that is attached outside of your existing window. This extra casing creates a pocket of air between the storm window and the interior window.

This air pocket, thus increases insulation for the home and can reduce energy loss by as much as fifty percent. Furthermore, adding a storm window to an existing window doesn’t cost even half as much as installing a new window.

The low-E glass takes this a step further. Low-E stands for low emissivity or low thermal emissivity. These windows are created by a very thin metal coating that reflects heat. It reflects internal heat back into the home and reflects external heat back outside of the home. This metal coating creates an additional layer of insulation that benefits energy usage even more so than your standard storm window.

Are storm windows worth The Investment?

In general, storm windows are already a great investment for any home. They can have a substantial impact on energy consumption, especially during the peak energy usage times. Peak energy usage times are hot afternoons during the summer and cold nights during the winter. These are also the times when electricity costs the most.

An average storm window is going to earn a return on your investment within 12 years at the most, but usually closer to 8, depending on where you live. As for a low-E storm window, the return could take as long as 7 years, but for many homeowners they see a return after only 4 years.
