What are the Best Replacement Windows?


When talking about what constitutes the best replacement windows, companies often toss around the terms “green,” “eco-friendly,” and “energy efficient.” What exactly do these terms even mean? Are these “eco-friendly” products backed by any sort of certification? And if yes, what does that mean for you?

There is a huge difference between energy efficient windows and non-energy efficient windows when considering the best replacement windows. Energy efficient windows help prevent air infiltration and can manage the amount of passing sunlight. These modifications and more help create energy efficient windows that can drastically decrease monthly energy bills and in the process help decrease environmental carbon dioxide levels.

A great way to determine if a window is energy efficient is if it is ENERGY STAR® qualified. The U.S. ENERGY STAR Windows Program is a joint program of the U.S. Environmental Protection Agency (EPA) and the Department of Energy (DOE) that identifies and promotes energy efficient products in order to reduce carbon dioxide emissions. So when you chose an ENERGY STAR qualified window you can feel confident knowing you’re not only helping the environment by reducing your carbon footprint, you’re also saving up to 15% on your monthly energy bill.*
