Are all Low E windows considered energy-efficient?

I’m buying windows for my home. What makes a window energy-efficient?

Yes, all Low-E glass is energy-efficient. Low-E glass, or low-emissivity glass, is a type of glass designed to reduce energy consumption and lower utility bills. Low-emissivity (Low-E) glass is crucial for energy-efficient windows as it minimizes heat transfer, helping keep your home warmer in the winter and cooler in the summer.
