One of the most important considerations for every homeowner when purchasing new windows is their energy efficiency. After all, your windows keep your home comfortable while reducing your energy bills day-in and day-out. In fact, heat gain and loss through your windows are the culprit for around 25 to 30 percent of your residential HVAC usage. This goes to show how important it is to choose quality, energy-efficient windows from the very beginning.
In today’s post, the leading double hung windows expert, Renewal by Andersen® of Atlanta, answers some frequently asked questions about energy-efficient windows.
What Is Insulated Glass?
Some homeowners think that “insulated glass” is just a single pane with insulating properties. While this isn’t the case, it’s actually two panes of glass separated by an argon filling in the gaps. Argon is used to prevent heat loss to keep your home energy-efficient and comfortable at the same time. These glasses are commonly used in both residential and commercial applications due to the savings that they provide.
U-Value vs R-Value?
Your windows installation expert will tell you that the R-Value measures how well a product can resist heat flow from your home’s exterior. This only applies to walls or ceilings, and a higher R-value means better insulation. U-value is used to measure the energy transfer for your windows and other fenestration products installed. Conversely, a lower U-value means that your product is more energy-efficient.
What Is Low-E Glass?
Low-E, or Low-emissivity, glass are panes that are coated with a material that reduces heat or UV transmission. In turn, this makes your windows more energy-efficient while reducing glare. This means that you no longer have to squint or experience uncomfortable temperatures when you’re using windows with Low-E glass.
