What is a good U-factor rating for windows?
between 0.17 and 0.39
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.
What does a 2.5 star energy rating mean?
More stars on the Energy Rating Label means the fridge or freezer is more energy efficient and cheaper to run – compared to models of a similar capacity. Whereas, a 2 star equivalent costs $43 more to run per year – which works out to be an extra $430 on energy bills over the life of the product.
What does a 6 star energy rating mean?

Do you want a higher or lower U-factor?
The lower the U-Factor, the better the window insulates. The SHGC measures how much of the sun’s heat comes through the window. It can range in value from 0 to 1.
What’s the difference between A+ and A ++ energy rating?
An A+ model uses as much as 20% less energy than the equivalent A-rated models, and their range of super- efficient models with A++ ratings use up to 40% less energy than an equivalent A-rated model.
What kind of light fixtures are Energy Star?
ENERGY STAR certified lighting offers energy-saving options for both in and outside the home, such as recessed lighting and outdoor porch lights. An ENERGY STAR fixture is built to last for many years.
