Not all windows are created equal! Homeowners often get lost in other decisions such as wall color and carpeting, but there are a variety of window glass types to choose from as well, and choosing the right one can be a big decision. With varying costs and different energy rankings, it is easy to get lost when it comes time to choose a window type. Last time, we looked at the difference between single and double pane window glass. Today we’ll look at a newer, more-advanced glass — low-e4.
Low-e4 glass was pioneered by Renewal by Andersen and sets a new standard in glass technology. The glass is easier to clean and goes a long way in cutting energy costs.
What exactly is low-e4 glass? The secret is the coating. Low-e4 glass has a special titanium dioxide coating on the exterior side that is activated by sunlight. The titanium dioxide reduces water spots and helps stop dirt buildup.
While the process behind low-e4 glass is complex, the results aren’t. It reduces up to 99 percent of water spots and can cut energy bills up to 25 percent.
Low e-4 glass is a newer technology, but is still widely used by Renewal by Andersen dealers. In fact, the glass is standard on all RBA windows.
Choosing a protective, energy saving glass like low-e4 can pay big dividends for homeowners.
