3 FAQs About Energy-Efficient Windows

Every high-performing home or building requires quality exterior features such as energy-efficient windows and skylights. While it is easy to determine the style of the window you want, finding the most energy-efficient window that falls within your budget range is not exactly a piece of cake. There are a lot of considerations as well as terminologies you need to learn. To help you, roof maintenance company Advanced Roofing has put together some of the most commonly asked questions about windows and energy efficiency.

1. What Is Insulated Glass?

Insulating glass refers to glass that is made to slow down significant heat transfer into or out of a home or commercial building. The term also means that there are two or more panes of glass, and the space between them is filled with a noble gas, which provides greater thermal efficiency.

2. What Is Low-E Glass?

Low-E stands for low emittance. A window with low-E glass means that the glass is coated with a razor-thin and colorless film material that acts to cut transmission of damaging ultraviolet rays from outside to inside. It is safe and can effectively improve energy efficiency, making low-E glass a standard in modern homes. A professional roofing installation contractor will recommend using low-E windows if you live in a particularly hot, humid area in order to make a remarkable difference in your cooling bill.

3. What Is the Difference Between R-Value and U-Value?

The term R-value is usually cited when discussing the insulation properties of walls and ceilings. It measures resistance to heat gain or loss. But since it does not translate exactly to windows, the industry uses the term U-value as an alternative. It is crucial to understand that these ratings have an inverse relationship. A higher R-value means walls and ceilings have better insulation, while a lower U-value indicates that the window is more effective in keeping out heat and cold.
