The Workings behind Energy Efficient Windows

The world has focused on the technological trend of energy savings and energy efficiency. At home, employing this technological trend can be a little confusing. This is especially true for windows because they look the same, of which many people ask the question, “how different or effective are they from other types of windows or what advantage is there in replacing your transparent window with an energy efficient one?” To understand the importance of energy efficient windows, here is a breakdown of some efficiency features that energy efficient replacement windows have to keep the house cooler in summer and warmer in winter (not forgetting the lighting factor).

Replacement Windows

Glass Coating

An energy efficient window features Low-E glass – a low emissivity glass – to help block 90% of the sun’s rays and keep the heat inside when it’s cold and outside when it’s hot. It comes with many glazing options, including tints, reflective coatings, and gas fills. This feature is meant to help you save on your heating and cooling costs in the house or office premise.

Spacer Systems

By employing 100% polymer structure foam instead of a metal as a window insulation, the window is kept thermally-efficient and condensation free, thereby blocking the heat’s escape path, which provides one of the best thermal performances.

Window Technology

Other means employed to achieve energy efficient windows include multiple panes of glass and the use of gas. Double paned and triple paned glass increases the blocking of ultra-violet rays from the sun. A triple paned window blocks up to 97% of UV rays from the sun, thus keeping you more comfortable year round and also prevents fading of fabrics, flooring, and other home belongings.

Filling the space between the insulated glass with Krypton further reduces heat transfer. Windows must be equipped with the appropriate glass, coatings, and spacers, otherwise they will be like a thermal hole. It is estimated that one-third of money spent in heating and air conditioning could be saved if energy efficient replacement windows were used.
