According to the U.S. Department of Energy, low-E windows can reduce energy loss by 30% to 50%. But the actual effect of low-E windows in your home will depend on many factors, like climate, number of windows, window treatments, and more. In terms of aesthetics, you may or may not notice a difference in how your windows look or how much natural light shines through. But overall, low-E windows look very similar to traditional windows.

In short, it depends. After 20 years, the glass in your windows is less energy efficient, which can cause increased electricity bills. You might also see signs of water damage or natural wear and tear over the years. However, with proper maintenance, some window frames can last up to 50 years, so you may only need to replace the glass to save on energy. 

At the same time, window replacement is a major investment, so replacing the glass in rooms most impacted by outdoor temperatures is one way to avoid going all-in to replace your windows.

Glass block windows are energy-efficient because they are much thicker than traditional glass panes, making them better insulators. They are sealed airtight, which prevents drafts and stops warm or cool air from escaping, helping to save money on heating and cooling bills. Unlike traditional windows that can be opened and closed, sealed glass block windows eliminate the potential for air leaks. For proven efficiency, look for options that are Energy Star rated. The cost for energy-efficient glass block windows is typically around $400 per window, which may be higher than standard windows.
