As our world shifts to energy savings and energy efficiency, home improvement can get a little confusing. Especially for windows because they look the same so many wonder, how are they any different from other types of window and what advantage is there in replacing windows? Well aside from lowered heating and cooling bills, there is a technology piece that plays a big role in how energy efficient windows work. To help clarify the way window technology works these days, the window pros at Window Nation have a breakdown of some efficiency features to keep you cooler in the summer and warmer in the winter.

Glass coating

For energy efficient windows, a Low-emissivity glass also known as Low-E glass is used to help block the rays of the sun (90% in fact) and keep the heat inside when it’s cold and outside when it’s hot. There are also many glazing options, which include tints, gas fills, and reflective coatings. Again, these are all used to help save you on your heating and cooling costs.

Spacer systems

To help keep your windows thermally-efficient and condensation free, 100% polymer structural foam is used instead of metal as a window insulation. Window Nation uses the Super Spacer® which lowers the U value or the rate of heat loss by .01. The lower the U value, the greater the efficiency of the window.

Window technology

Some of the latest technologies to windows are multiple panes of glass and the use of gas. Double paned and triple paned glass increase the blocking of UV rays. With a triple paned glass window, up to 97% of the UV rays will be blocked and this will keep you more comfortable year round and also prevent fading of fabrics, flooring and other belongings. Another great technology to energy efficient windows is filling the space between the insulated glass with Krypton gas to further reduce heat transfer.

Windows can be like a thermal hole if they are not equipped with the proper glass, coatings, and spacers. Some estimate that one third of the money spent on heating and air conditioning literally go right out the window. But with the many new technologies to energy efficient windows, all you have to do is worry about getting the old windows replaced! You can be sure that you will start saving money and have a more energy efficient home as a whole.
