Installing energy-efficient windows should be a significant consideration for every household. After all, heat gain and heat loss through your windows are responsible for around 25 to 30 percent of your residential heating and cooling usage. This is the reason why your choice of replacement windows is important in maximizing your home’s energy efficiency. However, with all the details and choices surrounding these windows, it can be difficult to make a decision.
In this post, Renewal by Andersen® of Seattle shares the answers to some frequently asked questions about energy-efficient windows.
What Is Insulated Glass?
Insulated glass has two panes of glass separated by an argon filling between them. Most homes and buildings use insulated glass on their windows and doors. These glass units provide excellent thermal efficiency.
What’s the Difference Between U-Value and R-Value?
Your window contractors would tell you that the R-value measures how well an insulation unit can resist heat flow. Walls or ceilings with a high R-value give better insulation. However, this doesn’t apply to windows and other fenestration products. This is where U-value comes in. U-value describes the amount of energy transfer that goes through windows and doors. A lower U-value means that the window or door is energy-efficient.
What Gases Are Inside IGUs?
The gas in between the window panes is responsible for preventing heat transfer through them. The gases inside the IGUs depend on their manufacturer. Some companies opt to use argon, krypton, or a mixture of both. Gases are a better insulator than air which increases your window’s thermal value.
What Is Low-E Glass?
Low-emissivity or Low-E glass units are coated with a clear material that reduces UV ray transmission. The coating makes your windows more energy-efficient, while reducing glare, and prevents damage to your furniture and flooring. It also helps improve the overall comfort of your home by keeping temperatures in check while reducing energy costs.
