High-performance, energy-efficient windows have become a standard in modern homes. As a homeowner, it is essential to know the components of a top-quality window, but the wide range of options available can make the selection process a bit overwhelming. To help you, we answer some of the best commonly asked questions about energy-efficient windows.
1. “What is insulated glass?” An insulated glass unit consists of two panes of glass separated by an inert gas. It provides greater thermal efficiency than standard windows. Its main advantage is the prevention of heat loss through the window, retaining heat or cold indoors and therefore saving energy.
2. “What is a gas-filled window?” Modern advances and technologies in window manufacturing have made it possible to seal an inert gas – usually argon or krypton – between panes of glass. Argon, for example, is non-toxic, clear and odorless. This gas is a better insulator than just air and further increases the thermal efficiency of a window replacement.
3. “What is the difference between R-value and U-value?” R-value is the measure of how well an insulating material resists the flow of heat. Since it does not translate directly to windows and other fenestration products, experts utilize the term U-value instead. A lower U-value indicates that the window is better at keeping out cold and heat.
4. “What is a Low-E glass?” A low emissivity (low-E) glass is coated with a clear film that minimizes the amount of infrared and ultraviolet (UV) light that travels through the glass. It cuts the harsh glare of the sun and staves off the damage that harmful rays can inflict on your furnishings.
