If you’re planning a window replacement this season, make sure to take into account the energy performance of your new units. After all, windows aren’t just lovely design elements that increase your home’s curb appeal–they are also great contributors to its comfort and efficiency. To guide you in choosing the best options for your home, Renewal by Andersen® of San Diego, premier windows and doors company, answers three of the most frequently asked questions about energy-saving windows.
1. What are double-pane windows? They are exactly that–windows that come with two panes of glass, plus an insulated space between. Double-pane windows are known for their thermal resistance, especially when that same insulated space is filled with insert gas. One of the better gas fills available today is argon, which is odorless, colorless, and non-toxic. It creates a greater insulating barrier between outdoor temperatures and your home, ensuring a more consistent indoor environment for your living space. The replacement windows offered by Renewal by Andersen® of San Diego all come with argon gas fill to ensure improved efficiency and overall performance.
2. What is the difference between U-Value and R-Value? When choosing replacement windows or French doors, check their U-value and R-value. The former measures how well your windows can keep out heat or cold–the lower the number, the better insulating performance your windows can provide. The latter, on the other hand, rates your windows’ ability to trap heating or cooling inside your home–the higher the number, the greater they are in preventing energy loss.
3. What exactly is Low-E glass? This refers to window glass with low-emissivity (Low-E) coatings that reduce the transmission of ultraviolet rays into your home. At Renewal by Andersen® of San Diego, we use something better than standard Low-E glass. Our replacement windows come with exclusive High-Performance™ Low-E4® SmartSun™ glass, which reduces the amount of solar heat entering your home, keeping it cooler and more comfortable–minus the high air conditioning bills. It also cuts glare and prevents extensive sun damage to your interior furnishings.
