Article first time published onWhat's a good U value for windows?
In a cold climate a good U-factor for a window is between 0.17 and 0.39. (That’s between R-6 and R-2.5). Lower is better with U-factor–the opposite of R-value, when higher is better. The low end of that range is only achievable with higher-quality triple-glazed windows–windows with three layers of glass.
Is Tempered glass more energy efficient?
Tempered glass is no less energy efficient than regular glass, especially when you go with a C5 Window from Conservation Construction. That’s because we still use all the same extraordinary coating on the glass that makes it energy efficient.
Which glass is better for windows?
