Window technology has come a long way since the highly-inefficient windows of yesteryear. Today’s windows are able to provide homes and offices with much better energy efficiency, which not only keeps a space at much more desirable temperatures but also helps owners save on monthly heating and cooling bills. So why are you still dealing with those old, single-paned windows? Don’t you think you deserve better?
Of course, there are many things that you need to take into account when choosing replacement windows. Although choosing windows with exceptional aesthetic appeal and finding the right Indianapolis window repair specialist to install them are both important considerations, choosing those that offer superb reliability and energy efficiency should take higher priority. It is essential that these items retain heat or cold effectively in your house to keep your utility bills– as well as your carbon footprint– at a minimum.
Choosing the right type of glass
It is important to consider the type of glass used in the replacement windows you will have installed. Traditional glass is known to be a poor insulator. Meanwhile, newer glass types like Low-E glass offer better insulation. A Low-E glass is coated with an ultra-thin layer of metal— called Low-E coating— that can either reflect or absorb heat energy.
What exactly is a Low-E coating and how does it work?
Eco Evaluator provides this definition for Low-E coating:
A Low-Emissivity coating, otherwise known as Low-E, is a thin film that is virtually invisible. […] Many of these products come with a ten to fifteen year warranty against fading, peeling and other signs of aging.
These coatings are designed to be spectrally selective and can allow for different levels of solar gain depending on your climate zone and design specifications. They are optically designed to reflect infrared light while allowing visible light to pass through virtually unobstructed. This allows the benefit of naturally lighting a space without the extra heat collected by the windows.
How is Low-E coating different from tinting?
Low-E coating is typically applied during the manufacture of the glass. Since it’s practically invisible, you can barely see it regardless of the thickness of the coating. Window film tinting is typically applied once the glass is already installed. Tinted or colored glass can be ordered from the manufacturer, and the thickness of the glass will determine the darkness of the glass.
