Everyone wants windows that are more energy-efficient, but there’s so much information out there that it can be hard to know what to do. At Progressive Insulation & Windows we are always happy to answer your questions. You can also keep reading to get answers to some of the most commonly asked questions about energy-efficient windows.
What is Insulated Glass?
Insulated glass has at least two layers of glass. Between those layers there is either air or gas. The particular type of substance between these layers can have a big impact on how energy efficient the window is.
What is Low E?
As you are looking for new windows, you are likely to see the term Low E used regularly. This refers to a metallic coating that is added to the interior of the glass surface. It works by reflecting or absorbing the warmth of the sun. Subsequently, it also reduces UV rays. Low E provides better U factor and solar heat gain coefficient.
What is Argon Gas?
It is odorless, non-toxic, and colorless. It is an inert gas that is used between panes of glass in place of air. Why? Because it helps to increase insulation, which then boosts energy efficiency as well.
What is U-Value?
The measure of heat loss is measured via U value. It also refers to how well a product has been insulated. The lower the number of the U value, the better the product works to insulate a building. The U factor is most important in cold, winter months but it can be very important in the scorching hot months of summer too.
What is Solar Heat Gain?
When you see the term “solar heat gain” used, it is showing you how successfully a product blocks heat that comes from the sun. A lower solar heat gain is better than a higher solar heat gain.
What is an R-Value
The R-value refers to the resistance to heat loss. This term is often more widely known than some of the other terms on this list because it is used in home insulation. It is also used for windows and doors. That said, U factor and solar heat gain coefficients are better measures of how insulated a home is.
What Exactly is Energy Star?
You have likely heard of Energy Star but you may not know exactly what it is. It is actually a joint program between the U.S. Department of Energy and the U.S. Environmental Protection Agency. There are several goals they have, including protecting the environment by helping people find more energy-efficient products, and helping consumers save money on energy.
