When it comes to replacing your old windows, it’s recommended that you choose a product that offers a good balance between energy efficiency and quality performance. It can be difficult to choose sometimes, so to help make a good decision, our window and roof replacement experts have answered some of the most frequently asked questions when looking for replacement windows.
1. “I’ve Heard of ‘Low-E Glass’ Before, But What Does It Mean?”
Low-E stands for low emittance. This means the glass is coated with a virtually clear material that cuts UV rays from outside to inside. A window that has a good Low-E glass can help improve the thermal efficiency of the window, reduce glare, and prevent damage that UV rays can cause to your furniture.
2. “How is R-Value Different From U-Value?”
R-value and U-value can be seen as two sides of the same coin. The term “R-value” is often cited when discussing matters such as wall and ceiling insulation value, but it doesn’t translate well to windows and other fenestration products. This is why the industry would often use the term “U-value” instead.
While R-value is usually cited in insulation literature and U-value appears in published material on windows, professional window and siding replacement contractors are also aware of how inversely related these ratings are to each other. Simply put, a higher R-value means better insulated walls and ceilings while a lower U-value means the window does a better job of keeping out the external heat and cold.
3. “Can You Help Me Understand How Gas-Filled Windows Work?”
Insulated glass consists of two or more panes of glass separated by insulation at the edges and air is filled in the center. This provides greater thermal efficiency for windows. You can also get insulated glass sealed with an inert gas (usually argon) in-between. Gas generally has much better insulating properties than just air, as it helps increase the window’s thermal value.
